dynamic load user controls

[guoqi zheng]

Dear Sir,

I have a menu page (main.aspx") with a placeholder on it. This placeholder
will load a a main menu item user controls (mainmenu.ascx), on this page,
there are a few menu items, When user clicks one of those menu items,
placeholder will be clean and load another user control (e.g. uc1test.ascx).
I have below code on click event at mainmenu.ascx, obviously these code did
not work out. What did I do wrong here?

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.
EventArgs) Handles Button1.Click

Dim abc As PlaceHolder = CType(FindControl("PlaceHolder1"), PlaceHolder)
Dim uctest1 As Control = LoadControl("uc1test.ascx")
abc.Controls.Clear()
abc.Controls.Add(uctest1)

End Sub

Can you be a little bit more specific? What isn't working? Is the event
handler (Button1_Click) being hit? if not, you need to re-add the
mainmenu.ascx user control in init or onload in order for the event to fire.

Guoqi,

I have some simple samples of dynamically adding controls to a page that I
think will help you. You may find the sample code at:
http://www.aboutfortunate.com?page=codelibrary

Type "dynamic controls" into the search box and you'll see the relevant
samples.

If you have any questions after looking at the sample code feel free to
email me.
