You can use the and GroupByChanging events for this. Here is an example:
public RadForm1(){ InitializeComponent(); radGridView1.DataSource = GetTable(); radGridView1.GroupByChanging += RadGridView1_GroupByChanging; radGridView1.GroupExpanding += RadGridView1_GroupExpanding;}private void RadGridView1_GroupExpanding(object sender, Telerik.WinControls.UI.GroupExpandingEventArgs e){ if (e.IsExpanded ) { e.Cancel = true; }}private void RadGridView1_GroupByChanging(object sender, Telerik.WinControls.UI.GridViewCollectionChangingEventArgs e){ if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.Remove) { e.Cancel = true; }}I hope this will be useful. Let me know if you have additional questions.
