Opening another panel on top orignal panel using a button

I need help in doing the following I have a project1 with a panel with a Button in it. When the button is selected will call project2 with a panel that has a different form and place this on the project1 panel. For example on the main panel has a button "click here" ------------------ | | | ButtonClick | | | | | | | | | ------------------ By clicking the button click here will then bring up a new panel over the orignal one. ------------------ | | | This is a test | | | | | | | | Cancel | ------------------ Click on Cancel will bring back the orginal form. I been looking at User Control but can not figure out how to to do this. Is there a simple sample code somewhere like this. I search but could not find anything. Any ideas would be helpful Thanks Marty
