Dear Support,

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:

    FrozenColumnCountLeftSet(1, false);

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.

Thanks,

Ron.

We tried to reproduce this issue. We did everything like you described and we invoked the GridCellJoinSet(CSize(1,2), 0, 0, 0, -1); code. But we cannot repeat the problem. Please help us to reproduce it. Here is the project:

Dear Support,

This is different from what I wrote - I don’t freeze column at top - I use two header columns at top.

Please update your application and you will see the bug.

Thanks,

Ron.

We updated the sample project for you. There are no bugs with cell joins.
