Question

I am in the process of learning how to implement custom controls by inheriting from parent classes in C#.

I need to override the routine that is fired when the user enters text. Obviously I could add an event to trigger using TextChanged, but this seems like dirty cleanup approach to me.

I have looked into override the Text {get;set;} property, but this does not work.

Help?

You can use the KeyDown event. Note that users can still paste stuff in without raising a KeyDown event. To catch all input, you need to handle TextChanged like you thought; there’s nothing dirty about it.
