Hi,
have you tried changing the display property of the panels to none on page load?
Something like:
Create a css class:
.hidePanel {display:none;}
Assign css class to panels
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
AdminPanl3.CssClass = "hidePanel";
StaffPanl3.CssClass = "hidePanel";
Panel6.CssClass = "hidePanel";
Panel3.CssClass = "hidePanel";
}
}
... hope it helps.
