WPF click on label change checkbox isChecked property

I’m new to WPF and try (in my opinion) an easy task but I didn’t get it. Even Google won’t help me, or I asked the wrong question.

I have a checkbox and a label; I wish that a click on the label change the isChecked property of the checkbox.

I want to do this completely in XAML with no code behind, because I wish to keep the code behind file clean of unnecessary code. Please don’t discuss on this point. I know it’s a single line of code doing this in code behind!

Working with event setter on the label doesn’t solve the problem because you can only set the handler (which is in code behind of course). Using a storyboard doesn’t help because there is no way to check the actual value of the property.

Does anyone have a good hint? Maybe I overlooked something. Please provide some code snippet for the solution.

Solution

  • Paste this code into kaxaml

    You'll see that clicking on the label toggles the checkbox.
