You could set ListIndex to -1 when your dialog closes. That will
"clear" the popup of any selection, putting it back to an initial

If you are using ShowModal for opening your dialog from your main
window just do:
MyDialogWindow.ShowModal // shows dialog
self.PopUpMenu1.ListIndex = -1 // executes when dialog closes or
hides
If you are not using ShowModal, just put the following in the Close
event of the dialog:
MyMainWindow.PopUpMenu1.ListIndex = -1 // be wary of implicit
instantiaton
The problem with this is that it keeps the PopUp from showing the
current
selection, which is important.
This is an example of where "new event" could come in handy.>
Create a custom Subclass of popupmenu.
Give it a property: lastTxt As String
Give it a new "Change" event: Change (txt As String)
In the custom class's Change event:
lastTxt = Me.Text
Change lastTxt // passes lastTxt to the instance's change event.
In the custom class's 'MouseUp' event:
I tried Phil's "new event" suggestion, which is pretty cool (and I
learned
something from it), but has a fatal flaw: The MouseUp event doesn't
fire
unless you pass True to the MouseDown event, and when you do that
RB assumes
you're handling the whole shebang and nothing pops up at all.
I also tried a Combo box, which isn't really suitable as my
categories are
fixed and therefore prone to user error (not to mention extra mouse
clicks).
Oddly enough, a Combo box returns a Changed event even when the
user chooses
the same category again. Odd, because it's super is PopUpMenu and I
would
have expected them to behave similarly.
Any further suggestions?
Yes, indicate the current selection in an adjacent field(textbox, for
example) along with my earlier suggestion of reseting the popup, or
use a listbox. The listbox has much more event/property/method
capability than the popup.
