panel control

I want to use 2 panels on 1 page with different information in it.

Now I want Panel 1 to be Visible True and Panel 2 Visible False

How can I best switch between the 2 panels?

Also keep in mind I don't want the page load to be reloaded.

Is this possile?

Please sent me an example on how I can get this to work.

simple as toggling the display properties from visible=true to false and vice versa.. BUT that area has to be reloaded.

you might be better off using a tab control and some ajax.  David is correct in that the area around the panel has to be reloaded, but using ajax will cause just that section to be reloaded.

Here's a quick video on how to do it:

See this working sample. Here Panel1 is shown while 2 is not visible and when we show Panel2 , 1 is hidden
