convert querystring to panel control

Question

I have a bunch panels on a page. panel1, panle2 ..., I want to make a panel visible based on a querystring. Ived tried:

Dim s As String
s = Request.QueryString("s")
Dim p As Panel = CType(Me.Controls(s), Panel)
p.Visible = True

This doesn't work. Maybe there is a whole different way to go about it. Thanks.

如果您要传递实际的面板ID（例如， http://mysite.com/page.aspx?s=panel1 ://mysite.com/page.aspx?s=panel1），则应使用“ FindControl”方法：

Dim p As Panel = CType(Me.FindControl(s), Panel)
