WPF (C#) Usercontrol remove elements

Question

I am making a template using Usercontrol in WPF(C#).

However, when applying this user control, is it possible to subtract a specific part? For example, removing a button?

Answer 1

It sounds like you are just trying to hide an existing button, which you should do by setting Visibility to Visibility.Collapsed or Visibility.Hidden . This should be done through a binding to the ViewModel of your user control.

If you need a pure XAML solution: No it is not possible as such. However, the reverse is possible: you can add content to a user control , and that effectively provides the same functionality.

What you could do is make a base user control that doesn't contain the button, and instead has a content presenter. A second user control could wrap the base user control and define a button as its content. Then when you don't want to use the user control with the button you can simply create an instance of the base user control.

Answer 2

To substract specific parts from UserControl, Visibility (Collapse, Hidden) option can be used. Make sure to add dependency property in UserControl for Visibility to show & hide specific part.
