If you use the following line, you can know how many rows are selected when you are in the event handler :
private void gridControl1_SelectedRowsChanged(object sender, EventArgs e)
if( gridControl1.SelectedRows.Count == 10 )
//do what you need
There is no way of knowing if the user is still selected more rows at that time however.
