Preventing resizing of columns from within a covered range. (IgnoreHeaders doesn''t seem to work.)

[Richard Deverson]

Hi,
I have a grid with a couple of Row Header rows.

I have merged (added covered ranges) some of the cells of the first Row Header row.

The problem is that the user can still resize the column widths by moving the mouse into the covered range of cells. I.e. the mouse cursor changes to the resize columns cursor, even though the column boundary is not visible within the covered range.

Is this the intended behaviour?

I have tried this:
gridControl1.ResizeColsBehavior = GridResizeCellsBehavior.ResizeSingle | GridResizeCellsBehavior.IgnoreHeaders | GridResizeCellsBehavior.InsideGrid;

IgnoreHeaders doesn't seem to have any effect, as far as I can see.
I hoped that by setting the IgnoreHeaders flag, I could prevent column resizing from within the headers, as a workaround.

By the way, I am using Syncfusion 3.3.0.0

You can avoid seeing this sizing cursor by handling the ResizingColumns event.

void gridControl1_ResizingColumns(object sender, GridResizingColumnsEventArgs e)
{
    if (e.Reason == GridResizeCellsReason.HitTest)
    {
        GridRangeInfo range = this.gridControl1.CoveredRanges.FindRange(0, e.Columns.Left);
        if (!range.IsEmpty && range.Right != e.Columns.Right)
        {
            e.Cancel = true;
        }
    }
}
