$
0
0

This example demonstrates how to process authenticated requests on the OData service. The main idea is to override the DataService.OnStartProcessingRequest method and implement authenticated logic in it.

To access this service, use the following credentials:

UserName: John
Password: qwerty

I was wondering why this project is not compatible with Visual Studios Ultimate 2010? Thanks

Added By: Joseph Tang 3 at: 10/10/2013 7:57:30 AM    

I used your code with the modification that it would check the AD for authentication. It works. However, it always popup the login window for entering the username and password.

How to bind a report displayed in the DocumentViewer extension to the model's data

December 25, 2013, 4:24 am
$
0
0

This example demonstrates how you can bind a Report in your ASP.NET MVC application to your model class.


Note:

Starting with version 14.2 (2014 vol 2), use the ObjectDataSource component to bind your report to your Model class schema as demonstrated in the How to: Bind a Report to an Object Data Source help topic.

In earlier versions, to populate the XtraReport Field List window with your model properties, add the BindingSource component to your report, as shown in the Providing Data to a Web Report help topic.

What I completely DO NOT understand, which therefore leaves me perplexed right this moment is: HOW DID YOU BIND THE REPORT TO THAT "POCO" CLASS IN DESIGN MODE? This is what I am dying to know!

Added By: Vasily (DevExpress Support) at: 1/13/2014 11:51:46 PM    

Hi Mark,

It seems that the same task was discussed in the Q562556: Is there a way to bind a report to a custom model class at design time thread. Please refer to it.

Added By: Prayagraj Dedaniya at: 4/19/2015 11:51:35 PM    

Hi,

In this Example I think You have not Given the Definition of the class "CategoriesReport" used in the Home Controller "DocumentViewerPartialExport" Action method.  So It is bit Difficult for me to understand. So I am requesting you to please Give me Code for the defination of the "CategoriesReport" class ASAP.

Added By: Dmitry Tok (DevExpress Support) at: 4/20/2015 1:19:29 AM    Hello,

Please download this Code Example and open it in Visual Studio. You'll find the definition of the CategoriesReport class in the Reports folder of the project. I've also changed the structure of this Code Example, so that the corresponding source code files are now available for preview.

This code fails with session-based non-persistent classes when Refresh action is called:

"The error occurred:
Type:       SessionMixingException
Message:    The 'Example.Module.MyNonPersistentObject' object belongs to a different session."

void application_CustomProcessShortcut(object sender, CustomProcessShortcutEventArgs e)

       IObjectSpace objectSpace = Application.CreateObjectSpace();
       e.View = Application.CreateDetailView(objectSpace, objectSpace.CreateObject<MyNonPersistentObject>(), true);
       e.Handled = true;
   }
}

How to solve it?

Added By: Dennis (DevExpress Support) at: 7/1/2015 11:26:44 AM    @DKx: It is wrong to inherit non-persistent classes from the base XPO classes like BaseObject, XPObject, etc. Use session-less POCOs instead (like demonstrated in this example).

How to export the GridDashboardItem item data to Excel from a web solution

In this example, you will find how to implement server-side export of the GridDashboardItem data from an ASP.NET solution using the report suite. The export is performed in three steps:
1. We request data displayed in a specific dashboard item using a client-side script provided in the T182186: How to get visible data from a certain dashboard item on the client side and process it on the server side example and send this data to the server in the form of a JSON string.
2. The JSON string is parsed on the server side. Based on the retrieved data, we generate a report containing a simple table.
3. Finally, it is necessary to export the report to an Excel document and write this document to the response. It is possible to use the same approach to export the resultant report to other file types.

How to emulate the dxLookup behavior using the dxPopup, dxList and dxCheckBox widgets

At present the dxLookup does not support templates. So, the only way to customize it (e.g., implement multiple selection or show several columns) is to emulate its behavior using other widgets.

Question Comments
Added By: FredrikE at: 10/8/2013 4:17:06 AM    

The dxList seem to loose its scrolling functionality when using it in a dxPopup. Try extending the list of OS:es in the sample like this:
        os: new ArrayStore([
            { name: 'Win3_1' },
            { name: 'Win95' },
            { name: 'WinMe' },
            { name: 'Win98' },

How to filter a LookUpEdit by multiple columns

The easiest way to search by multiple columns in LookUpEdit is to use the SearchLookUpEditStyleSettings class as demonstrated in the How to: Create a SearchLookUpEdit and Bind it to Data article.

If you would like to filter by multiple columns when a user types directly in the edit box instead, create a LookUpEditStrategy descendant and override the UpdateDisplayFilter method where the filter criteria is set.

GridView - Batch Editing - A simple implementation of an EditItem template

June 5, 2014, 7:44 am
$
0
0

This example demonstrates how to create a custom editor inside column's DataItem template when GridView is in Batch Edit mode.

You can implement the EditItem template for a column by performing the following steps:

1. Specify column's EditItem template:

[C#]
       settings.Columns.Add(column=>       {           column.FieldName="C1";           column.SetEditItemTemplateContent(c=>           {               @Html.DevExpress().SpinEdit(spinSettings=>               {                   spinSettings.Name="C1spinEdit";                   spinSettings.Width=System.Web.UI.WebControls.Unit.Percentage(100);                   spinSettings.Properties.ClientSideEvents.KeyDown="C1spinEdit_KeyDown";                   spinSettings.Properties.ClientSideEvents.LostFocus="C1spinEdit_LostFocus";               }).Render();           });       });


2. Handle grid's client-side BatchEditStartEditing event to set the grid's cell values to the editor. It is possible to get the focused cell value using the e.rowValues property:

[JScript]
       function Grid_BatchEditStartEditing(s, e){           var productNameColumn = s.GetColumnByField("C1");           if(!e.rowValues.hasOwnProperty(productNameColumn.index))               return;           var cellInfo = e.rowValues[productNameColumn.index];            C1spinEdit.SetValue(cellInfo.value);           if(e.focusedColumn === productNameColumn)                C1spinEdit.SetFocus();       }


3. Handle the BatchEditEndEditing event to pass the value entered in the editor to the grid's cell:

[JScript]
function Grid_BatchEditEndEditing(s, e){var productNameColumn = s.GetColumnByField("C1");if(!e.rowValues.hasOwnProperty(productNameColumn.index))return;var cellInfo = e.rowValues[productNameColumn.index];
            cellInfo.value = C1spinEdit.GetValue();
            cellInfo.text = C1spinEdit.GetText();
            C1spinEdit.SetValue(null);}

 

4. The BatchEditRowValidating event allows validating the grid's cell based on the entered value:

[JScript]
function Grid_BatchEditRowValidating(s, e){var productNameColumn = s.GetColumnByField("C1");var cellValidationInfo = e.validationInfo[productNameColumn.index];if(!cellValidationInfo)return;var value = cellValidationInfo.value;if(!ASPxClientUtils.IsExists(value) || ASPxClientUtils.Trim(value) === ""){
                cellValidationInfo.isValid = false;
                cellValidationInfo.errorText = "C1 is required";}}

 
5. Finally, handle the editor's client-side KeyDown and LostFocus events to emulate the behavior of standard grid editors when an end-user uses a keyboard or mouse:

[JScript]
var preventEndEditOnLostFocus = false;function C1spinEdit_KeyDown(s, e){var keyCode = ASPxClientUtils.GetKeyCode(e.htmlEvent);if(keyCode !== 9 && keyCode !== 13)return;var moveActionName = e.htmlEvent.shiftKey ? "MoveFocusBackward" : "MoveFocusForward";if(grid.batchEditApi[moveActionName]()){
                ASPxClientUtils.PreventEventAndBubble(e.htmlEvent);
                preventEndEditOnLostFocus = true;}}function C1spinEdit_LostFocus(s, e){if(!preventEndEditOnLostFocus)
                grid.batchEditApi.EndEdit();
            preventEndEditOnLostFocus = false;}
