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

Please send to support@codejock.com the sample code with crash.

Thank you.

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.
