Column not groupable after GroupDesriptors.Clear()

[Yves]

Dear Telerik team,

We have a gridview that allows the user to group, but when the user navigates to another page, we want to reset the grouping, e.g.:

        private void OrderingBookView_OnUnloaded(object sender, RoutedEventArgs e)
        {
            grvOrderingBook.GroupDescriptors.Clear();
        }

But when the user navigates back to the page, the column on which the grid was grouped the first time, can no longer
be grouped or filtered. The header of the column does not respond to clicking or dragging. Any other groupable columns can still be
grouped or filtered, just not the one that was in the groups at the time of the Clear.

Any ideas?

Best regards,

Yves.

Hello Yves,

Unfortunately I am not able to reproduce any problem applying grouping after I clear the currently added GroupDescriptors.

Do you do anything else once the view is loaded back? What is the result if you invoke this code on a button click instead?

Hello Didie,

You are correct, it works if I use a basic telerik grid.
The problem is somewhere in the company library that customizes the telerik controls.

Sorry to bother you with this,

Best regards,
Yves.

Hi Yves,

You can debug in details on what settings are set related to the grouping functionality.
