Define aggregates for row totals in codebind

[invDev]

Hello,

I'm trying to use some row totals in our application just like in your example: ( http://demos.telerik.com/silverlight/#GridView/Totals )

In our scenario the whole grid is built in c# codebind and i tried to adapt the xaml code to c# with no success. Could you give me a short example how to achieve this?

Thanks for your help,

Jonas

codebind = codebehind ...

Hello Jonas,

 

You may use our online documentation, where you can see how to define the AggregateFunctions of different columns in code-behind, following this link.  Regarding the fact in this example are used different DataTemplates I believe that the easiest way to achieve this result is to store the corresponding named DataTemplates within a UserControl's ResourceCollection and then reference it in code-behind as shown below:

this.radGridView.Columns[0].GroupHeaderTemplate = this.Resources["GroupHeaderTemplate"] as DataTemplate;

Please give it a try and let me know if you need any further assistance!

Thanks! Now, I've just one last problem: when using the SumFunction instead of the Aggregate- or CountFunction and add this to the DataColumn, the result is an unknown runtime error in a complete different part of the code. The DataType of the column is Int32.

This is the error:

{System.Exception: Schwerwiegender Fehler (Ausnahme von HRESULT: 0x8000FFFF (E_UNEXPECTED))
   bei MS.Internal.XcpImports.CheckHResult(UInt32 hr)
   bei MS.Internal.XcpImports.CreateObjectByTypeIndex(UInt32 typeIndex)
   bei System.Windows.DependencyObject..ctor(UInt32 nativeTypeIndex, IntPtr constructDO)
   bei System.Windows.Controls.Primitives.Popup..ctor()
   bei PV.UI.Classes.ModalControl..ctor()

Hi Jonas,



I tried to reproduce the problem in a sample project but was not able to. 
Please find it attached and let me know what changes should I make in order to observe the unwanted behavior. Furthermore to avoid any further misunderstandings you may send us in a new support ticket small repro application which we can test by our side.



Kind regards,
