Add an expander (collapse/expand) to a Panel WinForm

Question

I have a panel containing a DataGridView and 3 buttons at the bottom of a form. I want to add the possibility to expand and collapse this panel. Is there a way to do it in a Windows Forms application?

Has someone done something similar?

Answer 1

The SplitContainer control has the ability to collapse one of its two panels. You could rig up a button to the Panel1Collapsed property.

Answer 2

Take a look at my WinForm expander control - https://github.com/alexander-makarov/ExpandCollapsePanel

In general, it must meet all the basic requirements for this kind of control.

• Easy editing in Form Designer
• Put any control that you want into the content region
• Apply different styles and sizes
