@Register Programmatically

[Yet another C# coder]

Dear all,

Is it possible to register a UserControl Programmatically?
I am using a xml/xslt transformer to create some controls and then use the
Page.ParseControl to create
the webcontrols. I was wondering how I must add my UserControls without
adding any @Register tag inside my aspx file.

Thanx.

This is how you load a control programmatically:

string LoadControlStr = "/usercontrols/mycontrol.ascx"; //this would be
the location of your control
Control thisControl = LoadControl(LoadControlstr);
pnlContent.Controls.Add(thisControl); //this would be a panel on your
page

You can load the control dynamically as Grant noted. However, be aware
that there are a host of potential 'issues' with dynamically loaded
controls IF you are doing postbacks. In essence, a lot of the inner
workings that the ASP.NET page model handles for you automatically,
you'll need to do.

I've got a number of articles on working with dynamic controls, check
these two out to get started, though:
