Hello telerik,
I have tried to implement pagination using RadGridview, i have downloaded the latest WPF Q2 SP1 samples.. and looked into the example in GridView -> Performance - > Server page, sort etc...
When i tried to group the columns by dragging the column header on to the header droppable zone, items have been grouped.
but when i tried to change the current page to some other page by clicking any number on the Pagination control and after that when i tried to group the columns, it is throwing exception...
Is this a bug?
1) Launched the C# Samples from Start -> Programs -> Telerik
2) Select Grid View control -> Performance -> Server page, sort etc...Now able to see the radgrid view with pagination on the right panel
3) Click on second page ("2") on the pagination control
4) Drag any column header to group, I have dragged "Company Name" column.. Now error is thrown...
When i tried to debug i fournd the following as the inner exception:
"Unable to cast object of type 'Telerik.Windows.Examples.Customer' to type 'Telerik.Windows.Data.IGroup'."
Thanks,
Kranthi
