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,
