I have a windows application that runs in full screen and there are several panels in my form that I want them to stretch in width, I mean, how can I add width = 100% to this panel?
As shown in the figure below, the right panel is my inner (container panel), which should be stretched, it contains many elements: 2 panels, a toolbar and a grid. I just set Doc = "Fill" and Anchor = "top, right, left, bottom", but nothing has changed.
