I have ListBox (with SelectionMode=Extended) that has multiple items and I want to to add context menu feature. The problem is how to dynamically create context menu based on some conditions. Eg. I’d like to show regular context menu if only one item is selected but to show other context menu (eg. with some new items added) when more than one item is selected. In addition, I’d like to create third kind of context menu if among the selected item is at least one that has some property set. Etc… there can be multiple conditions like these.
Basically I need to dynamically generate context menu right after user has right-click the mouse button but just before the menu is actually shown. Is this possible?
I’ve found the answer to my question and it’s ContextMenuOpening Event.
Basically I need to handle this event and do menu adjustments according to the current application state. More details here: https://msdn.microsoft.com/en-us/library/Bb613568(v=vs.100).aspx
