Issue with filtering/hierachy in radgrid

[Ben]

Is it possible filter only 1 item at a time in the grid? For instance...if a user clicks the filter button, the row expands to display my controls. Now if the user filters a different row, i would like it to close the previous filtered row, then display the currently selected row.
I used the following example...

Hello Ben,

I'm not sure as to what you mean by filtering. From what I understand, I suppose you want to expand one row at a time in your hierarchial grid:
c#:

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
      if (e.CommandName == RadGrid.ExpandCollapseCommandName)
        {
          foreach (GridItem item in e.Item.OwnerTableView.Items)
             {
                if (item.Expanded && item != e.Item)
                  {
                     item.Expanded = false;
                  }
             }
        }
    }

Thanks
Princy.
