Dear Support,

I tried to change the color of the grid lines in my reportgrid by overriding OnGbwQueryGridLinesColor virtual method. But it never gets called. Even if I put a breakpoint in CExtGridBaseWnd::OnGbwQueryGridLinesColor(), it doesn’t step into that call (I checked if this method is overriden in any of your classes, but it doesn’t seem to be overriden).

If I’m not mistaken, the gridlines are drawn in CExtReportGridWnd::OnGbwPaintCell method, with the FillRect call in this part of code:

...
	if(		GridLinesHorzGet()
		&&	hTreeItem != NULL
		&&	nChildCount == 0L
		)
	{
		COLORREF clrFace = OnSiwGetSysColor( COLOR_3DFACE );
		dc.FillSolidRect(
			rcCell.left,
			rcCellExtra.bottom-1,
			rcCell.right - rcCell.left,
			1,
			clrFace
			);
	...
	}
...

I think clrFace should be taken from OnGbwQueryGridLinesColor, right? (It returns the same color in the default implementation.)

Thank you!

Yes, you are absolutely right. Please replace COLORREF clrFace = OnSiwGetSysColor( COLOR_3DFACE ); code with COLORREF clrFace = OnGbwQueryGridLinesColor(); in the ../Prof-UIS/Src/ExtReportGrid.cpp file.
