How to load a user control dynamically in a page?
I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.
What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.
As a result I am loading all the user controls on each postback.

In my one asp.net web page by VS 2008 I dynamically creates a set of RadioButtonList and TextBox by objects
[code]
The current issue is I can load the web page with a set of RadioButtonLists and TextBoxs but can't find the these dynamically built controls by Me.FindControl("rdoTask" & ID) in aspx.vb file to save info assigned to these controls.
i have:
- Default.aspx;
- user1.ascx: 1st user control containing repeater;
- user2.ascx: 2nd user control containing a detail view of row.
In page.aspx i dinamically load the repeater inside a user1.ascx.
after i want to dinamically load the 2nd user control also in default.aspx by a button inside a user1.ascx.
How i can do this? I can't load user2.ascx inside user1.ascx but only in aspx page.
