Invert row selection

I cannot find an easy way to invert the current (row) selection in a grid. What I am trying to do is the following: I want to let the user select some rows, then press a button and have the selected rows unselected, while the previously unselected rows should become selected. Can you help, please? Thank you.

Here is one solution that worked for me.

private void button1_Click(object sender, System.EventArgs e)
{
	GridRangeInfoList rangeList = this.gridControl1.Selections.GetSelectedRows(true, false);
	this.gridControl1.BeginUpdate();
	for(int row = 1; row <= this.gridControl1.RowCount; ++row)
	{
		GridRangeInfo range = GridRangeInfo.Row(row);
		if(rangeList.AnyRangeContains(range))
		{
			this.gridControl1.Selections.Remove(range);
		}
		else
		{
			this.gridControl1.Selections.Add(range);
		}
	}
	this.gridControl1.EndUpdate();
	this.gridControl1.Refresh();
}

That worked fine! Thank you!
