CTreeView problem

[salman83]

Hi all,

I created a treeview with style

TVS_HASBUTTONS |
TVS_DISABLEDRAGDROP |
TVS_HASLINES |
TVS_LINESATROOT |
TVS_CHECKBOXES |
TVS_SINGLEEXPAND

When OnInitialUpdate is called, I insert the items into the tree control, everything is fine with inserting the items. But, the problem raises when I set some items to checked state using GetTreeCtrl().SetCheck( hItem, TRUE ). But, it does not show the checked symbol on the item node. Whereas when I query for GetTreeCtrl().GetCheck, it returns me TRUE. I did this in OnInitialUpdate function.

Regards,

Salman

PostMessage a user defined message (from WM_APP range) from OnInitialUpdate to the treeview itself. Then in this message handler call GetTreeCtrl().SetCheck(...).

Hi VictorN,

Thanks for the reply. But, why I need to post a user defined message.

Thanks.

To fix the problem you have!

And FYI: the same problem exists for the initial selection in the tree view control; if you call GetTreeCtrl().SelectItem from within OnInitialUpdate (or OnInitDialog in the dialog containing tree control) the selection is NOT displayed.
