Method not found: System.String System.Web.UI.WebControls.ListControl.get_SelectedValue
-
I'm getting the following error when I post an aspx page and attempt to retrieve the values of web server listbox controls: "Method not found: System.String System.Web.UI.WebControls.ListControl.get_SelectedValue" Seems I can't grab the values of listbox web server controls (see http://www.benefitsonline.ca/Travel/British\_Columbia/Secure/BCTravel\_Daily\_App.aspx). Strange thing is, at another web host (and domain) the page works fine (http://www.iabc-health-insurance.ca/Travel/British\_Columbia/Secure/BCTravel\_Daily\_App.aspx). Any ideas? Possibly the .NET Framework is corrupt?

from the msdn docs for SelectedValue: "Note: This namespace, class, or member is supported only in version 1.1 of the .NET Framework. " which means that the host that it doesn't work on... is running .net 1.0.
