I have a RadCartesianChart and want to register for ContextMenuOpening. When I do it in XAML my event handler gets called. If I do in code (e.g. MainWindow_Loaded: Chart.ContextMenuOpening += Chart_ContextMenuOpening) it is not called.


I got a small repro too.

Hi Markus,

Did you forget to attach the project you mentioned? I can't see it attached to your post. Can you please upload it again?

I couldn't reproduce the problem you mentioned in a simple app. Perhaps the problem is more complicated, so a demo project that demonstrates it will be very helpful.

Hello Markus,

I checked your project and everything seems to be ok. I didn't find a context menu opening event handler added to xaml or in code behind. I added one in code behind and it is called as expected. To test it actually I added a dump in the output. So download the attached project, build it, run it and observe the Output window of your Visual Studio. It should print "Chart_ContextMenuOpening".

Hi,


In MainWindow.xaml.cs Line 62



// UNCOMMENT THIS

// Chart.ContextMenuOpening += Chart_ContextMenuOpening;




At the same time remove



ContextMenuOpening
="Chart_ContextMenuOpening"


from MainWindow.xaml in Line 13

Hello Markus,

I downloaded the project that Yavor uploaded and I can see that the 62nd line in MainWindow is not commented and there is no ContextMenuOpening="Chart_ContextMenuOpening" anywhere in the code.
Just as Yavor explained upon clicking the right button of the mouse the ContextMenuOpening event is raised and a line is added in the output window. Do test the provided project and see that everything works as expected.
