I'm using the technique described here to render a User Control to a string and it all works fine when the control contains just plain HTML, but when I try adding some server controls to the UC (like asp:button) I get the following error when calling server.execute:

"Error executing child request for handler 'System.Web.UI.Page'."

any ideas why/how to fix it? thanks.

  • Attach Visual Studio to the w3wp.exe process and break on all managed exceptions (ctrl-alt-e). This would give you (and us) more information about stack trace and error messages. Commented Jul 8, 2009 at 9:05

The problem was that the UC should have been added to the form's control collection, not the page's.

Could you try to include a call to EnsureChildControls() before to render to a string. This way you force the page to render the entire control tree first.
