Your code is wrong. Page_Resize can be raised multiple times. It will cause multiple layouts to be loaded. There is also no reason for this code. Just create the layout with the designer and load it when the page is created. It is very simple.

(Why do you want to stretch your layout? There are much better options available with anchors and the designer script). Page_Resize is called whenever the root panel is resized. You can uncheck the "Handler Resize Event" option in the layout file if you don't want it to be resized automatically.

Yes, it is a mistake. It is much simpler to handle the page resizing with the designer.
