Gridview Grouping

[Mark]

I am using Vlads datatable class to populate a gridview, the original one with dynamic linq. This works fine, however the grouping does not work. When I drag the column header over the grouping area I get the red circle with a slash and cannot drop the title.

<telerik:RadGridView RowIndicatorVisibility="Collapsed" IsReadOnly="True" CanUserFreezeColumns="False" <br>                                                         CanUserResizeColumns="False"<br>                                                         ItemsSource="{Binding ReportTable,Mode=OneWay}" />




There are no spaces in the title and they are unique.

Hi,

 Most probably there is something wrong with the column DataType. Can you try the latest version of the DataTable instead to see if you will have the same problem? 

Kind regards,

I did not actually assign a data type to the column, b/c the data is coming from an xml string I left it at what I thought would be the default of string, actually was null and therefore broke the grouping.

After explicitly setting the data type the grouping works.

Thank you.

The datatable classes were an excellent addition to the arsenal for getting around some of the Silverlight limitations, thanks to all the contributors.
