KwizCom Invisible Lookup Control

Scenario

• Installed KWizCom SharePoint Cascading Lookup Plus
• The web application you are configuring had an older version of AJAX extensions installed.

Issue

• The dropdown will not show up
• Or the entire page will continuously refresh
• This happens when the web.config is partially configured for 3.5.0.0 AJAX
• There will be an error in the Application Event Log
• The server tag "asp:scriptmanager" is ambiguous

Resolution

• Update the web application's web.config to use the 3.5.0.0 AJAX extensions
• You can do this by ensuring .Net 3.5 is installed and then creating a new test web application
• The new web application should have the .net 3.5 AJAX configuration in the web.config
• Use a text comparison tool to replace the appropriate sections
• Make sure to backup the old web.config before changing
