validation and Autopostback

My page has a wizard control and this wizard has several controls in it. I have a radio button list with two list items (YES & NO). This radio button list has Autopost back set to true. The reason being, on click of Yes button a Panel is displayed and this panel has many controls. On click of No the Panel is made invisible.

So the issue is that when i click the Yes button the Panel is displayed and if i then click next button of the Wizard control then validation summary is displayed saying to select data in the displayed panel. But then if i click No radio button the validation summary still appears and the post back doesnt happen.If i try to click the No button twice(that is click Yes and then click No again)then the postback happens and the Panel becomes invisible.

Please find the code below:

    if (rblLaptopPC.SelectedItem.Text == "Yes")

You may prefer to disable client-side java-script-based validation when displaying the panel and use only server side validation to deal with such complex scenario.
