load one or other user control

[Merkisson Jourhanssen]

When aspx is requested, load one user control or other based on queryString
value. How to do this? Note: only one user control to possibly appear on the
page at one time; and either of which to be loaded must appear in the same
place (in same <td>).

thank you.

You could use the LoadControl method to load the appropriate control at
runtime.
Here's the details:

Use a placeholder to define where you want them to go, then add conditional code something like this

PlaceHolder1.Controls.Add(LoadControl("myFirstCont rol.ascx")

If you need the user controls to participate in viewstate, make sure you load them during PageInit (PageLoad is too late for viewstate)

Thank you Bill.

Does PlaceHolder controls render in any way to HTML in browser, or used only
on server side to place other control?

No, it doesn't render anything, just a handy way to reserve a spot in the control tree
