I have an aspx page in a web (vb.net) application with a sqldatasource and I am trying to drop a listview into the designer view of Visual Studio 2010, but I am getting the following error in the designer view:
Error Creating Control - ListView1
Failed to create designer 'System.Web.UI.WebControls.ListView, System.Web.Extensions, Version=220.127.116.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
Some related oddities:
My web.config doesn't list version 18.104.22.168 anywhere.
When I hover over the ListView in the Toolbox, it claims to be Version 22.214.171.124.
All the other data controls (DetailsView, GridView, etc.) appear to work in designer view
I've tried resetting the toolbox items, but that didn't work. If you've seen this before and resolved it, please let me know what you did, I am quite baffled! I can provide screenshots and code if needed. Thanks in advance!
