I am looking for ways to let user/developer know that the control template of a certain control has been initialized.
To be more specific lets say for example I have a custom ComboBox and the ComboBoxItem control which is inside Popup of my ComboBox should notify me when its ControlTemplate was initalized. I have no access to ComboBoxItem which is why I cannot use OnApplyTemplate
of my custom ComboBox.
ComboBoxItems are not there from begin on since I need to open the Popup to see them.
What kind of ways do you guys use to find this out?
