I have a quick question regarding windows forms. Say I have a main form and it has a toolstrip with 2 buttons on it. Lets say one button displays a calendar form in the main form and the other displays a list of contacts in the main form. What is the best way to do this? Do i need to hide the one form when another form link is clicked or is there an easier way to do this? I just want more than one form to be shown in the mainform buy clicking on the corresponding button. Also the calendar and contact form will actually be in a splitcontainer panel inside the main form.
