Question

I have a hybrid application that I need to update a WPF control whenever an event is fired in the windows form.

I have a button click that will change the property of a string value, and depending on the string value, the WPF control should either draw a line or a rectangle. So when the user clicks either line or rectangle, how I transmit that to the WPF control?

Any help would be greatly appreciated!

Answer 1

Suppose You have A WPF UserControl named WPFUC. And and an ElementHost named elementHost1. And elementHost contains WPFUC. And the WPFUC has a public property named String Parameter. Then:

WPFUC userControl = (WPFUC)elementHost1.Child;
userControl.Parameter = "line"; //To draw line
or
userControl.Parameter = "rectangle"; //To draw rectangle

Hope this helps.
