I have a grid with two header rows.
I add a merge to the two left-most cells like this:
GridCellGetOuterAtTop(0, 0, RUNTIME_CLASS(CExtGridCellHeader));
GridCellGetOuterAtTop(0, 1, RUNTIME_CLASS(CExtGridCellHeader));
GridCellJoinSet(CSize(1,2), 0, 0, 0, -1);
This works fine. However
, when I try to make the first column frozen, by adding this line:
There is a bug - the joined cells suddenly have a line drawn in them like that are not joined anymore, but the text id drawn as they are joined... It seems that the draw of the background forgot that the cells are joined, but the draw of the text did not forget...
Please send us a patch to fix this problem.
