Hi Anand,

If you want to expand a particular group, you may use the ExpandGroup() method of the grid. In case you require only a single group to be expanded at a time, you may benefit from the approach demonstrated in this blog post. However, your implementation may be similar to:

GridViewGroupRow lastExpandedGroupRow;
void clubsGrid_GroupRowIsExpandedChanging(object sender, Telerik.Windows.Controls.GridView.GroupRowCancelEventArgs e)
        {
            if((e.Row as GridViewGroupRow).IsExpanded == true)
            {
                if(lastExpandedGroupRow != null)
                {
                    lastExpandedGroupRow.IsExpanded = false;
                }
                lastExpandedGroupRow = e.Row as GridViewGroupRow;
            }          
        }
 

Kind regards,
