What is the best way to organize layout in WPF?

Question

.NET

Hello!
I have minimal layout experience in WPF, i.e. Of course, I know how to draw a window, a grid-grid in it, and buttons on it, but exactly how to better layout a relatively complex interface is a problem with this.
Technically, I need a menu with many options - radio buttons, checkboxes, tabs, dropdowns, buttons.

At first, I drew all the buttons, checkboxes, etc. graphically. However, when I needed to move a group of elements, for some reason, when the frame was drawn, it was not the group of elements on the tab that began to stand out, but the tab itself. As a result, I began to draw stupidly in xaml, winding up a bunch of grids in which I stuffed the elements. However, in the end, I got a product that, apparently, will have to be further typeset in xaml

. For example, I made up such a misery.


Immediately questions:
was it right to do this, or was it worth it somehow differently?
A fragment of the code of one of the elements (everything is not inserted for some reason, 10 thousand characters limit)
