Can the dialog be placed on the form like other controls, e.g. ListBox or TextBox?
A question with a subtext about how to place a treeview on a form. Since I can define a dialogue with TreeView and ScrollBar, ProgressBar controls, I would like to then place it on the form like any other control. Unfortunately I can't find anything on this subject.

The goal in the link is the same, but that's not what I'm asking about.
I have created a dialog box with treeview support, but it is a pop-up window called from the code, which is as intended. I would like to embed this window permanently in the form and treat it like any other control.

And the question is how to embed a dialog box (in this case with a ready-made treeview, but generally any dialog box) in the form?
