Hi Somnath,

You can use the CurrentRowChanging event to prevent changing the current row (respectively the selection in RadGridView):

private void radGridView1_CurrentRowChanging(object sender, CurrentRowChangingEventArgs e)
{
    e.Cancel = this.radGridView1.SelectedRows.Count == 5;
}

The code above is applicable when multi-selection in RadGridView is enabled.
