GridViewRow.IsExpandable not working for child grids

[Aeroth]

Hi Telerik Support,

I've seen the post http://www.telerik.com/community/forums/silverlight/gridview/gridviewrow-isexpandable-not-working-for-child-level.aspx
and I have the same issue. Could you show me how to disable (+) sign if the row does not have any child items for the nested child grids? Thanks!

Hi Maya,

I don't have any xaml files so how can I set GridViewRow.IsExpandable for nested child grids programmatically?

Hello Aeroth,

There should be no problem to achieve the same behavior by defining everything in code-behind. What are the troubles that found on the implementation ?

Hi Maya,

I've resolved the problem by handling child grid's RowLoaded event:

private void _gridView_DataLoading(object sender, GridViewDataLoadingEventArgs e)
{
GridViewDataControl grid = sender as GridViewDataControl;

            if (grid.ParentRow != null)
            {
                grid.RowLoaded += new EventHandler<RowLoadedEventArgs>(_gridView_RowLoaded);
            }
}
