PropertyGrid crashes after ResetContent

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I tried to change an existing PropertyGrid.
At first, i tried calling ResetContent(), and then adding new items. This works,
but when i try to open a value list, eg. the {true, false} list of a bool item, the program
crashes. When having a look with the debugger, the in-place list box control
seems to be unitialized (HWND=0).
My second try was deleting the old property grid, and then creating a new one,
but this had the same effect.
Do you, perhaps, have a static in-place list box control, which gets by mistake
destroyed, when calling ResetContent() of a a property grid, or deleting it ?
I updated to XTP 7100, but still have the same bug.
Regards,
Norbert Irmer

	The bug is not so easy to reproduce. I have one docking pane, which contains a listctrl with a list of objects, and a second docking pane with a property grid, which shows the attributes of the currently selected object. In the listctrl, i track with OnLvnItemChanged the focused object, and recreate the property grid, when another object is focused. The bug is, that when i press the button which opens the in-place listbox of the property grid, i get ON_NOTIFY_REFLECT(LVN_ITEMCHANGEDOnLvnItemchanged) for the object list contained in the first docking pane !!! (even though this list isn't focused, and doesn't change at all) I will try to get this away by maintaining some internal state variables, but something with the XTP message handling is utterly wrong in regard to the in-place listboxes of property grid items Regards, Norbert Irmer
