Missing event in NTTabPage

[ruppschtaler]

Hi there,
My add-on uses an AddOnFrameworkWindow with TabControl and multiple NTTabPages.
I'm missing an event in NTTabPage when MainTabControl's selection has been changed to update global objects like an InstrumentSelector in MainMenu of AddOnFrameworkWindow.

Unfortunately MainTabControl's event OnItemsChanged() is protected and not accessible.
Any ideas?

Many thanks for your help!

Hello ruppschtaler, and thank you for your question. According to the publicly available MSDN documentation,

This method is called when there is a change in the items collection of a ListView control.

While this suggestion is untested, it may be the case that creating your own child class of ListView and adding an instance to replace the main one, and then adding the MainTabControl's children as children of this listview (after saving references to each of the MainTabControl's children and then removing them so that they only ever have one parent), will give you a ListView you can control, with an OnItemsChanged method you can write yourself. You may need to dispatch the reparenting calls to the MainTabControl object.


Doing the above is an exercise to you, and is outside the scope of the support we typically provide. However we are happy to answer any questions as they come up.
