2008.3.1125.35 VS2008 SP1
Tried to follow this example but it's not working: http://www.telerik.com/help/aspnet-ajax/grdfilteringwithdropdownlist.html
I created MyCustomFilteringColumn.vb with these headers:
Namespace MyCustomNamespace
Public Class MyCustomFilteringColumn
Inherits GridTemplateColumn
In ASPX page I have:
<%@ Register Namespace="MyCustomNamespace" TagPrefix="custom" %>
<custom:MyCustomFilteringColumn DataField="Opt_In" HeaderText="Customer ID" UniqueName="CustomerID" />
I get a bunch of warnings and it will error with: Parser Error Message: Unknown server tag 'custom:MyCustomFilteringColumn'.
Generation of designer file failed: Unknown server tag 'custom:MyCustomFilteringColumn'.
Namespace or type specified in the Imports 'MyCustomNamespace' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
