How to make textbox resize as the window resize

Question

Any property to set to make textbox to resize according to the window size?

Answer 1

One method would be to bind the height and width of the TextBox to the height and width of the Window, for example:

There may be a different property that might want to bind to, or you might want to use an expression so the TextBox isn't exactly the Height/Width of the parent window. A lot depends on your specific usage scenario, but this should be enough to get you started.
