This example illustrates an approach of including a GaugeControl image into a document generated via SimpleLink (DXPrinting).
In the example, a gauge's image is obtained via the RenderTargetBitmap.Render method. Before rendering, special code is executed to resize the control based on the target documents requirements.
This example illustrates how to dynamically create a custom report based on PivotGridControl content.
It also implements the following suggestions:
S130430: Support word wrap when printing and exporting
S91257: Utilize a Line color when printing
AS9011: Print row headers on every page on export/printing
and the S18650: Add an event that allows to provide custom size for field values (MeasureFieldValue, or so) suggestion for printing facilities.
Hello,
We are trying to implement this in our pivotgrid... we are getting an error under method FillDatasetColumns. We are getting an object reference not set to an instance of an object at line "tempColumnText +=pcea.GetFieldvalue(field).ToString()+ " | " Do not know what would be causing this??

I have the same problem, however, my report should contain three PivogridControl. According to this example does not work, have any suggestions?

Added By: John (DevExpress Support) at: 9/12/2014 4:41:16 AM Hi Ana,This example shows how a PDF document with the AcroForm data (interactive forms) can be exported either to the XML or FDF format.
This demo is based on the sample provided in example E1362. It uses custom callbacks to implement cascading comboboxes in a detail GridView. Two comboboxes edit two database fields. The value list in a depended control is filtered based on the value selected in master control.
I cannot get this example to work properly. I have followed it exactly using my own data. In the display grid (not in edit mode) the GridViewDataComboBoxColumn for Category2ID is displaying the ID value instead of the Textfield value even though the TextField and ValueField is set properly and both fields are returned by the data source. Also, when editing, the Category1ID Combobox never allows selection to occur and Category2ID is not updated.

To process your recent post more efficiently, I created a separate ticket on your behalf: T274803: E2156 example - GridViewDataComboBoxColumn shows thу value instead of the text. This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.
Scenario
In this example, we create a CloneIXPSimpleObjectHelper class that will be used to clone the provided persistent object.
Steps to implement
1. Implement the CloneIXPSimpleObjectHelper class as shown in the CloneIXPSimpleObjectHelper.xx file. This class uses persistent object metadata to create a copy of the provided persistent object.
The Clone method has several constructors that allow you to specify the target Session and determine whether object synchronization is required or not. If the synchronize parameter is set to true, reference properties are only cloned if the reference object does not exist in the target Session. Otherwise, the existing object will be reused and synchronized with the source. Set this property to false if the target Session does not contain an object of the source.
2. Create a Form that will use the ListBox control to display the result of creating and cloning persistent objects. See the code of the Form class in the Form1.xx file.
As a result, the following output will be shown:

Should I use XPO to transfer data between databases?
There's a little catch with this code. Primary Keys are changed, so it doesn't make a real clone, but a copy. You have to change the code a bit so the primary key gets synced too if needed.

Dear,
I face a real problem with your clonehelper. After implementing we recoginized that this helper will not only clone my recordset, it will also clone/create my relations.
So, for example i have a order management where i want to clone one order. But what happened is that the order will be cloned, but the underlying addresses (relation via keys) will be cloned, too. So, after cloning 10 orders, i have 10 times the same address in my address-masterdata ?
Any idea ?
Added By: Chris D at: 8/4/2015 10:50:22 AMTo avoid creating the underlying record, i changed
If m.ReferenceType IsNot Nothing And NONEW=1 Then....
where NONEW=0.
Could you please have a short look if this is the right solution ?
Added By: Alexey (DevExpress Support) at: 8/4/2015 11:14:43 PM Hello Chris,This example demonstrates how to display a popup window with the filter editor before showing report preview, and filtering the report using the filter specified in this window. For this purpose, a custom report parameters class - CriteriaReportParametersObject - is created. This class has the Criteria property decorated with the CriteriaOptionsAttribute. XAF automatically uses CriteriaPropertyEditor for properties decorated with this attribute. So, the CriteriaPropertyEditor will be displayed in the CriteriaReportParametersObject DetailView. To convert the string created by this editor to the CriteriaOperator appropriate for the report, use the CriteriaEditorHelper.GetCriteriaOperator method in the CriteriaReportParametersObject.GetCriteria. The following topics contain more information about these techniques:

Added By: Mobilise IT at: 8/4/2015 8:49:19 PMHi,
I was looking for this function with ReportV2, is there any sample I can use?
This example demonstrates how you can use the Google Calendar API in your scheduling application. Google provides the corresponding guidelines regarding use of this API:
Google Calendar API
Before using this API, make certain you have read and understand Google’s licensing terms. Next, you’ll need to generate a corresponding JSON file with credentials to enable the Google Calendar API.
We have a corresponding KB article which contains step-by-step description on how to generate this JSON file:
How to enable the Google Calendar API to use it in your application
After you generate this JSON file and put it in the Secret folder of this sample project, you can import appointments from a Google calendar into the SchedulerControl;
1. Click the "Connect" button to generate a list of available calendars for your Google account
2. Select a corresponding calendar from which to import appointments.
For importing appointments, we created a corresponding CalendarImporter class which creates Appointment instances based on loaded Event (Google.Apis.Calendar.v3.Data) instances.
Appointment entries obtained via the Google API are objects of the Google.Apis.Calendar.v3.Data.Event type. Each appointment entry is processed to create an XtraScheduler appointment, recurrence pattern or exception. To parse recurrence information contained within the appointment entry, a RecurrencePatternParser class is implemented. It creates the DevExpress.XtraScheduler.iCalendar.iCalendarEntryParser instance to parse recurrence information represented by a string in iCalendar format. The DevExpress.XtraScheduler.iCalendar.iCalendarEntryParser instance holds the parse results and provides access to property values by property names.
Note that a special method is required to link exceptions (changed or deleted occurrences) with their patterns, since they are created independently while processing Google appointment entries.
P.S. To run this example's solution, include the corresponding "Google Calendar API" assemblies into the project.
For this, open the "Package Manager Console" (Tools - NuGet Package Manager) and execute the following command:
Install-Package Google.Apis.Calendar.v3
good morning to all,
thanks for the example

Hi,
I need help.How can i implement same code in my windows phone app using c#.
Thnaks,
Thanks for the example. I have downloaded the latest DLL's from the website. The code fails on line 111
UserProfile.Instance.Calendars = (CalendarFeed)service.Query(query);
the catch then says it is an invalid username/password. But I know these to be correct because I use them to login via chrome.
Can someone suggest what I've left out.
Regards.
Added By: Oleg (DevExpress Support) at: 7/6/2015 3:36:33 AMHello Stephen,
We were able to reproduce the issue. It seems that something was changed in Google API. We need additional time to investigate the issue on our side and find a corresponding solution.
We will update the status of this ticket once we have any results.
Thank you. Trawling through the system, it appears that oAuth is the way to get in, but working that out is like wading through treacle.
I know I have the export .ics on the schedulergrid but I have to delete all the calendar entries and then re-import as the web interface doesn't check for duplicates.
This example demonstrates how to manipulate ASPxHtmlEditor View Areas by CustomToolbarButton.
1) Wrap ASPxHtmlEditor with ASPxCallbackPanel to programmatically send a callback to the server;
2) Define CustomToolbarButton for ASPxHtmlEditor;
3) Handle the client-side ASPxClientHtmlEditor.CustomCommand event and perform a callback via the ASPxClientCallbackPanel.PerformCallback method;
4) Handle the ASPxCallbackPanel.Callback event and define View Areas enabled via the ASPxHtmlEditor.Settings property.
This example demonstrates how to implement two cascaded ASPxGridLookup controls:
To implement it, perform the following steps:
1) Handle the server-side ASPxGridLookup.Init event of a "detail" lookup and subscribe to the CustomCallback event of a nested ASPxGridView object;
2) Handle the client-side ASPxClientGridLookup.ValueChanged event of a "master" lookup;
3) Perform a custom callback of the "detail" ASPxGridLookup via the ASPxClientGridLookup.GetGridView().PerformCallBack method;
4) Handle the "detail" ASPxGridView.CustomCallback event and define a filter expression for a "detail" datasource based on selected values of the "master" lookup;
5) Save a modified select command to the session to load it when the "detail" ASPxGridLookup/ASPxGridView is initialized after a callback.
This does not work inside editform template.

It would be great if you register a new ticket in our Support Center and describe what error you are facing with the sample project from this Code Example.

It is better to assign the report in the ASPxDocumentViewer's OnLoad event. And it is only necessary to do it upon a callback or a postback. Callbacks occur when the ASPxDocumentViewer is shown, and postbacks occur when a button on the ASPxDocumentViewer's toolbar is clicked. This has the advantage, that when the page contains other controls that produce callbacks like grids, the report is not created, saving processing time. I also found out, that there is no need to call this.DocumentViewer1.DataBind(), it does not seem to make any difference. Therefore, Default.aspx.cs can be written as follows:
using System;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
protected void DocumentViewer1_Load(object sender, EventArgs e)
{
if (IsCallback || IsPostBack)
{
var hf = (HtmlInputHidden)this.Page.FindControl("ReportMsg");
var report = new XtraReport1();
report.Parameters["test"].Value = hf.Value.ToString();
report.CreateDocument();
this.DocumentViewer1.Report = report;
}
}
}
The OnLoad event must be added to DocumentViewer1:
<dxxr:ASPxDocumentViewer ID="DocumentViewer1" runat="server" ClientInstanceName="DocumentViewer"
ShowLoadingPanelImage="False" LoadingPanelText="" OnLoad="DocumentViewer1_Load">
<SettingsSplitter SidePaneVisible="False" />
</dxxr:ASPxDocumentViewer>
Scenario
If you want to use XAF report in non-XAF application, then you can follow these instructions to achieve this.
Since XAF stores reports in the database, and XAF reports use the ObjectSpace to retrieve data from database, it is necessary to connect to the XAF database and create ObjectSpace to use XAF reports in a non-XAF application.
Steps to implement:
1) Create a custom class which implements the IReportObjectSpaceProvider interface. Please refer to the ExportXafReport\MyReportObjectSpaceProvider.xx file for implementation details.
2) Create a custom class which inherits the ReportDataSourceHelper class and override the CreateReportObjectSpaceProvider method as shown in the ExportXafReport/MyReportDataSourceHelper.xx class.
3) Create ObjectSpace using the approach from the Access XAF Application Data in a non-XAF Application article and register required types in the TypesInfo. Please refer ExportXafReport/Program.xx file.
4) Use the approach described in the How to: Print a Report Without Displaying a Preview article to access and print a report.
This example contains XPO and EF implementations.
This example demonstrates how to resize a DevExpress ASP.NET control (for example, ASPxPageControl) to occupy the entire browser window (a Full Screen mode)
1) Reset the following default CSS rules for a page:
[CSS]body,html{padding:0;margin:0;}
2) Set the ASPxPageControl.Width property to "100%" and set an initial ASPxPageControl.Height property;
[ASPx]<dx:ASPxPageControl...Height="100px"Width="100%">
3) Set the ASPxPageControl.Paddings.Padding to "0px" to disable default offsets/paddings (this step is optional);
[ASPx]<dx:ASPxPageControl...><PaddingsPadding="0px"/></dx:ASPxPageControl>
4) Implement a function that should resize the control within the entire browser window;
5) Call this function when:
- the control is initialized for the first time (handle the client-side ASPxClientControl.Init event);
- the browser window size is changed/resized (subscribe to the "resize" event and handle it via the client-side ASPxClientUtils.AttachEventToElement method):
[ASPx]<dx:ASPxPageControl...><ClientSideEventsInit="OnInit"/></dx:ASPxPageControl>
[JScript]function OnInit(s, e){ AdjustSize(); ASPxClientUtils.AttachEventToElement(window, "resize", function(evt){ AdjustSize();});}function AdjustSize(){var height = document.documentElement.clientHeight; pc.SetHeight(height);}

Since Prism RegionManager supports standard controls only, it is necessary to write custom RegionAdapters (a descendant of the Microsoft.Practices.Prism.Regions.RegionAdapterBase class) in order to instruct Prism RegionManager how to deal with DXDocking elements.
This example covers the following scenarios:
Using a LayoutPanel as a Prism region. The LayoutPanelAdapter class creates a new ContentControl containing a View and then places it into a target LayoutPanel.
Using a LayoutGroup as a Prism region. The LayoutGroupAdapter creates a new LayoutPanel containing a View, and then adds it to a target LayoutGroup’s Items collection,
Using a DocumentGroup as a Prism region. The DocumentGroupAdapter behaves similarly to the LayoutGroupAdapter. The only difference is that it manipulates DocumentPanels.

InnerException:
Hello, we have an issue with your sample E3339 (related to the use of regions and adapters). The sample is successfully working with the 11.2.11 version in one of our testing computers. But we’re now integrating the last version of DevExpress (12.1.4) in our sandbox computer and it doesn’t work: the project is compiling but it doesn’t work (the adapters aren’t working: the flow execution isn’t entering in the adapters, in the function Adapt). We’re experiencing the same problem than K.Wessing: System.ArgumentException was unhandled by user code
Message=This RegionManager does not contain a Region with the name 'LeftRegion'.
We have been checking your technical support and it seems there was another issue between the 11.1.x and the 11.2.x, and your teams adapted the sample project for the new DevExpress version. Is it possible that it’s happening the same?
Thanks,
Juan Lopez
I am using the LayoutGroupAdapter
I would like to be able to switch from one view to an other within the same LayoutGroup region.
I 've added the Remove action:
if (e.Action == NotifyCollectionChangedAction.Remove)
{
regionTarget.Items.Clear();
}
Scenario:
in region : <dxd:LayoutGroup cal:RegionManager.RegionName="{x:Static Infrastructure:RegionNames.DetailsRegion}" />
#1 Add a viewA - OK
#2 Remove viewA - OK
#3 Add viewB - OK
#4 Remove viewB - OK
#5 add viewA - Getting ERROR below
Please advice.
Thank you

The Remove event is not handled in the documentgroup adapter which does not reclaim the memory when tab is closed.

Added By: Sergey Wereteychenko at: 9/3/2013 12:27:27 AMWhy this example is so bugged?
After detaching a panel - disappears a content, please try detach Toolbox...
And why this example craches every time, when attach-detach event happening...
Please, supply Working example.

Cause of removing content is "lp.Content = null;" row...
Why was existing this row in example?
Can you complete the code for remove action. We have something as below to remove any tabs that are floating or in the default layout group. it does not find tabs in newly created layout groups.
case NotifyCollectionChangedAction.Remove:
List<DocumentPanel> panelToRemove = new List<DocumentPanel>();
List<FloatGroup> floatGroupToRemove = new List<FloatGroup>();
DockLayoutManager managerRemove = regionTarget.GetDockLayoutManager();
foreach (DocumentPanel panel in regionTarget.Items)
{
foreach (IPanelInfo oldItem in e.OldItems)
{
if (panel.Caption.Equals(oldItem.Title))
{
panelToRemove.Add(panel);
}
}
}
foreach (DocumentPanel pnl in panelToRemove)
{
regionTarget.Items.Remove(pnl);
}
panelToRemove.Clear();
foreach (var floatGroup in managerRemove.FloatGroups)
{
foreach (DocumentPanel panel in floatGroup.Items)
{
foreach (IPanelInfo oldItem in e.OldItems)
{
if (panel.Caption.Equals(oldItem.Title))
{
panelToRemove.Add(panel);
}
}
}
foreach (DocumentPanel pnl in panelToRemove)
{
floatGroup.Items.Remove(pnl);
}
if (floatGroup.Items.Count == 0 )
{
floatGroupToRemove.Add(floatGroup);
}
}
foreach (FloatGroup floatGroup in floatGroupToRemove)
{
managerRemove.FloatGroups.Remove(floatGroup);
}
break;
Added By: Artem Dubenko 2 at: 8/6/2015 12:54:59 PMUnfortunately this example doesn't support selection/activation of the views. A call to IRegion.Activate(view) will have no effect.
If you need to modify the GridView filter right before it is sent to the DataController, you can use the ColumnView.SubstituteFilter event.
This example demonstrates this approach.
This example illustrates how to sort groups in the report by the number of records in each group.
For more information, see Sorting Data.

This example demonstrates how to handle specific events of Property Editors and ObjectSpace, indicating changes with object in the Detail View.

Do you have a similar document for what listview controllers? This document was very helpful - it would be nice to have a similar document for listview.
Thanks
