How to create a textchange event for usercontrol

Question

I have a user control that contains a textbox and some buttons.

I can't respond to the text changed event from the textbox from outside of that user control (say from the parent form that the control is placed on).

How can I get an event that raised when the text has changed from outside of the user control?

Please see this answer on how to create a custom event in WPF.

Following this approach, you can handle the "TextChanged" event for the textbox inside your user control, then raise a custom event from there.

in your textcontrol event change, put this:

 Me.OnTextChanged(e)

Or create your own event

Upper code:

 Public Event ClaveModificada(Causa As String)

and when you need:

RaiseEvent ClaveModificada("")
