Brief overview of requirements for using Ajax with Sharepoint 2007 web parts

If you want to use the AjaxControlToolkit controls with Sharepoint 2007,

Notes/Checklist:

• Installed the Ajax Server Extensions
• Installed the AjaxControlToolkit
• Upgraded Sharepoint to Service Pack 1 or later
• Upgraded WSS 3.0 to Service Pack 1 or later
  
• Copied the AjaxControlToolkit.dll file to the bin folder of your portal under C:\Inetpub\wwwroot\wss\VirtualDirectories\yoursite\bin
• Updated the Web.config by adding relevant entries to support Ajax -> C:\Inetpub\wwwroot\wss\VirtualDirectories\80\web.config (copy entries from web.config in a website you created by using the Ajax Enabled website starter kit in Visual Studio)
• FORGET ABOUT SMARTPART or any other 3rd party web parts that convert user controls into web parts. That was a crude workaround for versions of sharepoint before service pack 1.
• Use the web part development add-in for visual studio (use it to develop, deploy and debug)
  
• Add Scriptmanager control to your masterpage
  
  <WebPartPages:SPWebPartManager runat="server"/>
  
  <asp:ScriptManager ID="ScriptManager1" runat="server"/> <-- that is exactly where you must insert it
• Remember to publish your masterpage after adding the scriptmanager
• Toolkit controls have to be dynamically constructed in web part codebehind
• If your webparts are iterating through sub-sites remember to use the SpSecurity.Delegate functionality as described in an earlier post in this blog.
