It's possible to use the non-visual RichEditDocumentServer component to adjust the required document settings. Create a new document using RichEditDocumentServer and adjust its page by using the corresponding API.
Refer to the following documentation articles, where you can learn how to set the required properties:
This example demonstrates how to set a document page's landscape, paper kind, margins and font properties.
This examples demonstrates how to display images in the CheckedComboBoxEdit edit box and its dropdown window when the editor is used in bound mode. This task is accomplished at an editor descendant level.
To show images in the dropdown window, it is necessary to set the RepositoryItemCheckedImageComboBoxEdit.ImageMember property to a column name whose values represent Image objects or a byte array. If you wish to display these images in the edit box, you should also set the RepositoryItemCheckedImageComboBoxEdit.ShowImagesInEditBox property to true.
This example demonstrates basic approaches and code snippets that can be used to add a DashboardExtractDataSource to the ASPxDashboard control. The Extract data source is often used if it requires a lot of time to request data from a database using a complex query or a stored procedure. The DashboardExtractDataSource allows you to request this data once and save it in the compressed and optimized form to a file. Then it will be possible to load data from this file and prepare a new file version when data is updated. This concept is described in the Faster Dashboards with the “Data Extract” Source blog.
The following code snippet is used to create a DashboardExtractDataSource and connect it to a DashboardSqlDataSource. Note that I use the CommandTimeout property to increase the query timeout:
[C#]DashboardSqlDataSourcenwindDataSource=newDashboardSqlDataSource("Northwind Invoices","nwindConnection");SelectQueryinvoicesQuery=SelectQueryFluentBuilder.AddTable("Invoices").SelectColumns("Customers.CompanyName","Address","City","Region","PostalCode","Country","Salesperson","OrderDate","Shippers.CompanyName","ProductName","UnitPrice","Quantity","Discount","ExtendedPrice","Freight").Build("Invoices");nwindDataSource.Queries.Add(invoicesQuery);nwindDataSource.ConnectionOptions.CommandTimeout= 600;DashboardExtractDataSourceextractDataSource=newDashboardExtractDataSource("Invoices Extract Data Source");extractDataSource.FileName=GetExtractFileName(path);extractDataSource.ExtractSourceOptions.DataSource=nwindDataSource;extractDataSource.ExtractSourceOptions.DataMember="Invoices";
To add the data source to the ASPxDashboard control use the solution described in the Register Default Data Sources help topic:
[C#]DataSourceInMemoryStoragedataSourceStorage=newDataSourceInMemoryStorage();dataSourceStorage.RegisterDataSource("extractDataSource",GetExtractDataSource(path).SaveToXml());ASPxDashboard1.SetDataSourceStorage(dataSourceStorage);
The UpdateExtractDataSource method is used to extract data from a database. Note that it is impossible to update a used file, thus a new file is always created:
[C#]vards=GetExtractDataSource(path);stringfileName=DateTime.Now.ToString(extractFileName);ds.FileName=path+"Temp\\"+fileName;ds.UpdateExtractFile();
In this example, data is extracted on a button click. However, in a real-life application, this solution can be insufficient (e.g. the site may be deployed to the web farm server). We recommend creating a separate windows service that should update data automatically every hour or every day.
At last, the ConfigureDataConnection event is used to connect the data source to the latest file version:
[C#]protectedvoidASPxDashboard1_ConfigureDataConnection(objectsender,ConfigureDataConnectionWebEventArgse){ ExtractDataSourceConnectionParametersextractCP=e.ConnectionParametersasExtractDataSourceConnectionParameters; if(extractCP!=null){ extractCP.FileName=...; }}
At the moment, BootstrapGridView displays cells in CheckBox columns as images which makes it impossible to edit these cells in a single click. First, you have to click the cell to enter the edit mode and the second click actually changes the value. It is not very convenient, so we created a workaround that allows editing such columns in a single click.
For this, define a data item template for the CheckBox column and place an actual check box there. Synchronize this check box with the item collection - obtain the value using the Eval (or Bind) method and set a new value with SetCellValue.
This example demonstrates how to save the custom data related to a dashboard to the dashboard XML definition and how to load this data later. In this example, the standard 'Save' menu item removed from the Web Dashboard menu. A new 'Save As' menu item allows end-users to add a custom comment appended to the dashboard XML definition. Moreover, the current dashboard state and modified date is added to the XML definition.
You can load dashboards containing custom data using the 'Open' menu item. A comment and modified date form the selected dashboard is displayed within the form at the top of the web page. The loaded dashboard state is applied to the dashboard using a client-side API.
The following API is used to implement these capabilities:
- The ASPxClientDashboard.GetDashboardControl method is called within the ASPxClientDashboard.BeforeRender event handler to customize the standard Web Dashboard menu.
- The ASPxClientDashboard.PerformDataCallback client-side method is used to pass the custom data to the server side. On the server side, the ASPxDashboard.CustomDataCallback event is used to obtain and parse these values. These values are saved to the dashboard XML definition using the Dashboard.UserData property.
- The ASPxDashboard.DashboardLoading event is handled to obtain the custom data from the UserData element when loading a dashboard.
- The ASPxDashboard.CustomJSProperties server-side event is used to pass the custom data obtained to the client side.
- The ASPxClientDashboard.DashboardChanged event is handled to display custom data related to the selected dashboard. Moreover, the SetDashboardState method applies the dashboard state.
Let's assume that there are Person and Address persistent objects. The Person class has an Address property of type Address. The Address class has a City column. The grid is bound to XpoDataSource with persons. The task is to display the Address.City value in a grid column. The solution is to set the grid column's FieldName to "Address.City".

Within the GridView.CustomSummaryCalculate event handler, it's impossible to access a total summary calculated against another column. The total summary can be obtained within the GridView.CustomDrawFooterCell and GridView.CustomDrawGroupRowFooterCell event handlers. Here, you can obtain a total summary value using the GridSummaryItem.SummaryValue property, and GridView.GetGroupSummaryValue method. For convenience, we suggest that you set the GridGroupSummaryItem.Tag property of group summary items to user friendly values. So, you can use these values to easily obtain a necessary GridGroupSummaryItem from the GridView.GroupSummary collection.

This example demonstrates how to color a specific ButtonEdit's button using the SkinMaskColor property by taking into account the current skin. The main idea is to create a ButtonEdit descendant as described in the Custom Editors help article. Then, override the ButtonEditPainter.DrawButton method in order to draw the required button using your own LookAndFeel object.
Note that you can set the required button's color using the EditorButton.Appearance.BackColor property at design time or in code.
This example shows how to access a single item by using LayoutGroupBase.FindItemByPath method.
Updated:
The ASPxFormLayout.FindItemByPath method and the LayoutItem.LayoutItemNestedControlContainer property are obsolete. It is recommended to use the ASPxFormLayout.FindItemOrGroupByName method and the LayoutItem.Controls property instead.
Hi
LayoutItem.LayoutItemNestedControlContainer is deprecated, can you please update the examples related to this property?
Thanks

Hi,
By default, when the xxxThemKey markup extension is used, resources are searched in the DeepBlue theme. When another theme is applied, it is necessary to use the ThemeName attribute in resource keys, for example:
BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=CellStyle, ThemeName=MetropolisDark}}"Thanks,

This example illustrates how to create a TemplateColumn for working with time values.
This example demonstrates how to dynamically create a report based upon the ASPxGridView control at runtime. This means that all filtering, sorting and grouping conditions selected in the grid are also applied in a report. To accomplish this task, it is necessary to create a report with all the necessary bands, bind it to a data source and adjust all the necessary options.You can use this approach if you need to display content of templated columns in your report or insert a report based on ASPxGridView to another report.

Dear support. I have been trying for several days now to export custom cell templates of a pivotgrid but with no luck. From my previous posts, I understand that the exporting of pivotgrid custom cells is not supported, nor are there any plans to support this in the future. This is a serious shortfall for us and could mean that we are just not able to use your controls if we are not able get the data out to the users.
I then came across this post which appears to be doing exactly what we need to do, although this is doing it against a ASPXGridView and not against a ASPXPivotGrid.
I have been trying to "translate" the C# code so that it instead works off of the ASPXPivotGrid but have not been able to.
Is there any chance that somebody there could provide the equivalent sample that will take a ASPXPivotGrid and create a report out of it which includes the templated cells? As an ideal example, if you are able to show how this code would work against your own templated example found here: http://demos.devexpress.com/aspxpivotgriddemos/Templates/CellTemplates.aspx
I have seen several posts now where users are requesting the ability to export templated cells from the pivotgrid, so I am sure any assistance/sample code you can provide along the same lines as what you have done here will be very useful for quite a few of us.
Thanks in advance

Added By: Cristiano2s at: 2/4/2014 11:18:30 AMHi,
this example works fine and it was very good to my application. But i need the same to excel, and when i did the changes i lost the header. Do you have the same example or just the part to export to excel?
Added By: Vijay Macha at: 5/29/2014 2:51:45 PMHi,
This example is great. Can we export GridviewBand column also in this approach. we are using devexpress 2014 v1.2
In ReportHelper.vb, in InitDetailsandPageheader cell.Text is set to the FieldName where I think it should really be set to the ColumnCaption to make use of the work done in GetColumnsInfo which selects the ColumnCaption to be the Caption if there is one or FieldName if there isn't. It certainly works better for me. This affects C#, VB and the MVC example code.
cell.Width = columns(i).ColumnWidth
cell.Text = columns(i).ColumnCaption 'Better to show the Caption than the examples columns(i).FieldName
row.Cells.Add(cell
I was able to replicate this example, to my needs, but unfortunately there is a problem with the tables label headers, because it does not use the one in the grid caption
How can I change this, since its using the class name, not the grid caption
Hello Jag Zao,
To process your recent post more efficiently, I created a separate ticket on your behalf: T216993: How to convert and then print an ASPxGridView by using the XtraReport + Keep Grid Caption. This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.
This example demonstrates how to add the "Save As" and "Delete" options to the MVC Dashboard control.
It requires only a few changes to utilize the solution described in the T466716: Web Dashboard - How to work with extensions article in MVC:
1. Use the SetDashboardStorage method to define the default storage:
[C#]protectedvoidApplication_Start(){...DashboardConfigurator.Default.SetDashboardStorage(newDashboardFileStorage(Server.MapPath("~/App_Data/Dashboards")));
2. Handle the client-side Init event using the DashboardExtensionSettings.ClientSideEvents property:
[C#]@Html.DevExpress().Dashboard(settings=>{settings.Name="Dashboard";settings.ClientSideEvents.Init="onInit";}).GetHtml()
3. Define a controller action that should be used to delete dashboards:
[C#]publicActionResultDeleteDashboard(stringDashboardID){CustomDashboardFileStoragenewDashboardStorage=newCustomDashboardFileStorage(@"~/App_Data/Dashboards");newDashboardStorage.DeleteDashboard(DashboardID);returnnewEmptyResult();}
4. Customize the DeleteDashboardExtension.deleteDashboard function to call the server-side DeleteDashboard action using AJAX:
[JavaScript]this.deleteDashboard = function(){var dashboardid = _this._designer.dashboardContainer().id; $.ajax({ url: 'Home/DeleteDashboard', data: { DashboardID: dashboardid}, type: 'POST',}).success(function(){ _this._designer.close();});}
