Asked On February 24, 2013 08:48 AM UTC

When I try to integrate the SfDataGrid without any binding to ItemsSource property, the App starts normally, but when I try to bind to my data the App crashes with an unhandled exception. The content of the exception is:

System.NullReferenceException at Syncfusion.UI.Xaml.Grid.SfDataGrid.UpdateRowAndColumnCount(Boolean canGenerateVisibleColumns) at Syncfusion.UI.Xaml.Grid.SfDataGrid.OnApplyTemplate()

 

The usage of the control is as follows:

<grid:SfDataGrid ItemsSource="{Binding Model.Orders}"/>

The binding works perfectly fine with other DataGrids (eg. from Telerik or with a standard ListBox).

Hi Pascal,

Thanks for using Syncfusion products.

We have analysed your query. When you bind an empty collection as ItemsSource to DataGrid, then you have to specify the SourceType for the DataGrid as shown in the following code snippet.

 Code Snippet [C#] :

this.grid.SourceType = typeof(Order);

 

Please let us know if you need further assistance.

Regards,

Prakash S.

if the collection is empty then the data grid should not throw an exception for sure..this is a bug

Will this be fixed in a future update?
