Solution 1

Something along the lines of:

C#

if (!IsPostback)
{
    Panel.Visible = 
        Panel2.Visible = false;
}

// logic to set one or the other panel to visible.

When page get postback all the controls get re-initialise. if you dont want to re-initialise use IsPostBack

C#

If(!IsPostBack)
{
       Panel1.Visible=false;
       Panel2.Visible=false;
}

Thanks

If you need to avoid postback even then too then An alternative to this solution (or which can be used in conjunction of this solution) is to move the panel2 inside an updaetpanel.
