I have an event trigger that I want to be fired in response to two different routed events. I don't want to repeat the event response code (in XAML) twice.

Hi, A very well known fact is that routed events only travel up or down the ancestry and not through all the elements. But an equally known fact is that an event handler can be wired in the common parent of two disparate controls. My questions is how, some pointers please.

I have attempted to subscribe everything possible, but can't find what it is which is handling it. Is there a way to find out what is? Or is there a way to have the event not handled, or for an encompassing UIElement to get to...

Hi everyone, There are a lot of discussions about M-V-VM and Command binding (RelayCommand) but not a lot has been covered on Routed Events binding to a handler in a M-V-VM pattern. I want to find what is the best approach. Here is an example of RoutedEvent binding using a custom event and a bound event handler to the VM. <Navigation:...
Hi, I have an Asp.Net web page, having the common Asp.Net form. The outer "border" of the page (i.e. main menu, header, ...) is build using normal Asp.Net code using a master page.

I'm adding a Click event that can be assigned in the button's XAML, like a regular button.

I'm struggling with the TagVisualizer control on an MS Surface project. In theory the control seems great, allowing you to respond to input from real world physical objects The problem is that the control will cover the entire screen (since I want to capture tags on the entire screen) and as such, no other controls in my app will receiv...

This is basically the same question as Q 1396153, but I'd appreciate a more favorable answer :) Is there a non-invasive way to do this? I am not sure exactly how to attach behavior to the Expander.Header content to prevent mous...
