C# event programming

[directhex]

I'm mildly embarassed to ask this, but it seems neither of the somethat introductory texts I own covers it, and I'm failing to find an online tutorial that doesn't suck.

I've got a window, which has a custom object on the left (a list of "modules", which are basically custom widgets) and a custom widget on the right (one of the custom widgets). I need to make it so that clicking on something in the left-hand list makes a change to what's being done on the right. As far as I can determine, the way to do this is with Events - the MainWindow.cs should have some method which handles changing the right-hand widget, and I need to rig up *something* that allows it to be executed when clicking something in the left-hand list.

So. What I need is a way is for my left-hand window (an instantiation of osctool2.OSCNavigation) to fire an event that the main window (osctool2.MainWindow) can detect, in order to delete and replace the right-hand window. Note that this isn't the same as the sub-widgets firing events (I'm already acting on osctool2.OSCNavigation.OSCNavigationTreeView.Selection.Changed, and the handler for this event is what I want to trigger the new custom event)

not sure i can visualise what it is your trying to do here.

But an event is happening on the left panel (call it L) and you want to call an event on the right panel (call it R)?

i want an event happening on the L to be acted upon by the main window (the one containing L and R).

i've never really tried to have an instantiation of an object call methods of other instantiated objects before

you know you can have multipule events bound to an object?

you can even use reflection an automatically "hook" an event that belongs to a class of a certain base type!

when you have two objects who are peers wanting to talk to each other, its easyest to get hte parent to do it. Or you can pass a referance to the events to be called to each other object.
