I am getting the error below when I open a new aspx page I just created in an existing web site using VS 2010 and Net 4 framework after adding a ListView to the page.
Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "AjaxControlToolkit.Properties.Resources.NET4.resources" was correctly embedded or linked into assembly "AjaxControlToolkit" at compile time, or that all the satellite assemblies required are loadable and fully signed.
Also, when I mouse over a squiggly underlined control inside the ListView I get the message below. Any ideas on where/how I can resolve this? Thanks.
Type 'System.Web.UI.WebControls.ListView' is not defined.
