Hello!
We are using RadControls for Silverlight 4.
I have downloaded the demo at http://demos.telerik.com/silverlight/#DragAndDrop/TreeToGrid
The only change I made is to MainPage.xaml, where I was forced to remove the reference to DefaultHeaderedContentControlStyle, which was not available to me.
The drag and drop between the various elements works fine, but if you try to reorder the columns, by dragging a column header to the right or left, you get a null reference exception.
The demo that appears on your site doesn't seem to produce an exception, but it does have odd behavior if you try to reoder columns by dragging the header. It causes a new row to appear in the grid, and the columns are not reordered.
Is there a workaround for this? Our users want drag and drop for rows, but they also want to be able to reorder columns.
Thanks,
Mike Maddux

Hi Mike Maddux,
In order to avoid the exception while dragging columns you can use the following code in each drag & drop handlers:
Please check this post -http://blogs.telerik.com/tsvyatkokonov/posts/10-05-20/enable_radgridview_rsquo_s_rows_reorder_functionality_using_behaviors.aspx - demonstrating row reorder functionality.
