ASP.Net: User controls added to placeholder dynamically cannot retrieve values

Question

I am adding some user controls dynamically to a PlaceHolder server control. My user control consists of some labels and some textbox controls.

When I submit the form

Ensure you are defining your dynamic controls at the class level and adding them to the ASP container:

Private dynControl As ASP.MyNamespace_MyControl_ascx

And when you instantiate the control, ensure you call LoadControl so the object is added properly:

dynControl = CType(LoadControl("~/MyNamespace/MyControl/MyControl.ascx"), ASP.MyNamespace_MyControl_ascx)
