When I resize ColumnChooser until scroll bar is shown. Then select the last partially shown column. The clicked column is active. But the next column got selected (checked). It seems like a bug. Are there a workaround?

I tried following in mouse down event. But it does not work. Any idea?

var

lastVisibleRow = columnChoorseGrid.ActiveRowScrollRegion.VisibleRows.OfType<VisibleRow>().Last();

columnChoorseGrid.ActiveRowScrollRegion.ScrollRowIntoView(columnChoorseGrid.Rows[lastVisibleRow.Row.Index + 1]);
