How can I organize controls on a form relative to each other and the form itself?

Question

I have a child form in an MDI Windows Forms application. It has two controls: ComboBox and TreeView, and the last under the first. Both controls are the same width. How can I customize them and form properties to achieve the following:

• When resizing a form, the width of both controls must be equal to the width of the form.
• The height of the TreeView must change to fill all the free space of the form.

Answer 1

You can do the following:

• In the form designer, create controls as you want them to look.
• ComboBox Anchor ,
• TreeView Anchor Top, Left, Right Bottom

Answer 2

, . Dock , "", .

, Combobox Dock=Top TreeView Dock=Fill:

, TreeView , .

Answer 3

Anchor. (combobox, treeview usercontrol), , .

The property is Docksimilar, but it also affects the location and kind of “sticks” the control into place even in the form designer.
