Cannot drag drop column headers into grouping panel

[Maria]

I'm unable to drag drop column headers into the grouping panel.  The grid below was simply dragged onto the user control and bound - no coded events, no customization.  When you try to drag the column header, it shows that dragging is disabled.

Here's the xaml:

            <StackPanel Margin="8">

                    <telerikGridView:RadGridView ItemsSource="{Binding Revision.FilingRevisionContacts}"/>
                </StackPanel>
            </StackPanel>
        </StackPanel>
    </Grid>
</UserControl>

I have same problem. I can drag but cannot drop column header. I set :
gridTemp.ClientSettings.Resizing.AllowColumnResize = true;
gridTemp.ClientSettings.Resizing.AllowRowResize = false;
gridTemp.ClientSettings.Resizing.ResizeGridOnColumnResize = false;
gridTemp.ClientSettings.Resizing.ClipCellContentOnResize = true;
gridTemp.ClientSettings.Resizing.EnableRealTimeResize = true;
gridTemp.ClientSettings.AllowColumnsReorder = true;
gridTemp.ClientSettings.ReorderColumnsOnClient = true;
gridTemp.GroupingEnabled = true;
gridTemp.ShowGroupPanel = true;
gridTemp.MasterTableView.GroupLoadMode = GridGroupLoadMode.Client;
gridTemp.ClientSettings.AllowGroupExpandCollapse = true;
gridTemp.MasterTableView.EnableColumnsViewState = false;

My RadGrid.Net2.dll version is Q4 2006

Hello Maria Hsiung,

I have tried to reproduce the problem here but with no success. Can you please send me a project that resembles the problem ?  ( to be able to attach the project please open a support ticket)

Hi ,

This forum section is about RadGridView for Silverlight . I believe you have placed the question here by mistake.

All the best,

I have the same problem, the issue is dragging only works when a row is selected. Selecting a row allows me to drag the headers, deselecting the row doesn't allow dragging.

Hi Brendan,

Does the problem occur with the latest official binaries - Q2 2011? Can you reproduce it on our demos?

I realised my problem was that the objects used in my grid required implementing the IComparable interface for filtering and grouping
