Hi Andre,

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.
