Let's say I have two webforms, A.aspx and B.aspx, where B.aspx contains some simple web controls such as a textbox and a button.

I'm trying to do the following:

When A.aspx is requested, I want to dynamically call and load B.aspx into memory and output details of all the controls contained in B.aspx.

Here is what I tried in the codebehind for A.aspx:

var compiledType = BuildManager.GetCompiledType("~/b.aspx");
if (compiledType != null)
{
  var pageB = (Page)Activator.CreateInstance(compiledType);
}

foreach (var control in pageB.Controls)
{
    //output some details for each control, like it's name and type...
}

When I try the code above, the controls collection for pageB is always empty.

Any ideas on how I can get this to work?

Some other important details:

• both webforms utilize a master page (so the web controls in b.aspx are actually placed within a "content" tag)
• I've also tried using BuildManager.CreateInstanceFromVirtualPath. No luck.
