Removing lines in multiple header data bound grid

The attached file shows a multi-line header in a data bound grid. Does anyone know how to remove the dashed line between header row 1 and header row 2? Any help would be greater appreciated- Thanks from Benno

You can try to remove the border in the header cells. Here is one way you can do it.

Thanks for that - I can remove the lines now ... but is there any way of actually making the cells become one ... like merge the cells? As the heading is now to two rows ... really would like it to become one - Also is there a way of changing the text alignment in a particular header cell?

You can use CoveredCells (and then you don't need to remove the lines - but you will only see the text from the top-left cell of the covered range appear in the 'new' larger cell). this.grid.Model.CoveredRanges.Add(GridRangeInfo.Cells(0,1,1, 2));
