How to add user control to panel

I have created multiple user controls in my project and what I need to do is to be able to switch between them on a panel control.

for example, if the user click button1, userControl1 will be added to panel after removing every control on it and so on.

I have this code :

panel1.Controls.Add(MyProject.Modules.Masters);

but it's not working.

How I can do it?

Isn't just easier.

panel1.Controls.Clear();
panel1.Controls.Add(new MyProject.Modules.Masters());

EDIT: Maybe try this...

panel1.Controls.Cast<Control>().ForEach(i => i.Dispose());
panel1.Controls.Clear();
panel1.Controls.Add(new MyProject.Modules.Masters());

You need to instantiate a new MyProject.Modules.Masters.

MyProject.Modules.Masters myMasters = new MyProject.Modules.Masters()
panel1.Controls.Add(myMasters);

This will only add a new control to panel1. If you also want to clear everything out of the panel before adding the control like you said in the question, call this first:

panel1.Controls.Clear();

You have to instantiate your controls. You will have to make sure the size is set appropriately, or for it to have an appropriate dockfill. 

var myControl = new MyProject.Modules.Masters();
panel1.Controls.Add(myControl);
