I installed 2.83, and want to merge cells in my tree grid - and it doesn’t work.

This is what I do:

I create a new node in the tree, get its HTREEITEM and call this line (I have a two columns tree):

GridCellJoinSet(CSize(2,1), 0, ItemGetVisibleIndexOf(hti));

What happens is very weird - it seems that the two cells in the row that I joined are being written one on top of the other...

Note that the two cells are of the type CExtGridCellString, the left one has a text value, and the right one is empty, what I wanted was that when the left column becomes narrow, the text will flow to the right column’s cell.

Is this a bug? is this feature available in tree grid? If not when will it be available?

I am sending you a clip via mail to show you to problematic behavior.

Dear Support,

I am using it in one row only (as you can see above: CSize(2,1) ) and still there is a problem in tree grid - I sent you a video clip shwing how it behaves.

We really need this feature in tree grid, as we need something similar to what you implelemted in property grid, when the category header occupies the whole width.

The cell merging feature has just appeared v.2.83. We tested it with the CExtGridWnd control. We can also make it working with CExtTreeGridWnd and non-grouped CExtReportGridWnd controls. In the case of tree grid, the user is responsible for merging cells in one row only or in scope of rows which have no child rows. But at present the merging feature is developed for the CExtGridWnd control only.
