How can I allow AJAX option in custom web part for SharePoint 2010?

Question

As http://weblogs.asp.net/jan/archive/2010/03/01/little-sharepoint-2010-gem-ajax-options-in-list-view-web-parts.aspx mentioned, I can select AJAX option for out-of-the-box SharePoint 2010 webpart.

But, how can I allow AJAX option in custom web part, I just created Standboxed & Non-Standboxed Web Part by VS 2010 and deployed to MOSS 2010 for quick test, but it's seems no related option can be selected.

Could you please advise me can I llow AJAX option in custom web part?

Answer 1

This is probably built into the web part and is not a general configuration setting for all web parts. Most likely you will need to add a script manager to the page (or master page) and then have your update panel within the actual web part. You also might be able to put the script manager in the web part, but it is generally a better idea to put it on the masterpage/page because you will see errors if there is more than one on a page.

Thank you for your advice ^^

ScriptManager scriptmgr = ScriptManager.GetCurrent(this.Page);
if (scriptmgr == null)
{
     scriptmgr = new ScriptManager();
     if (this.Page.Form != null)
     {
           this.Page.Form.Controls.AddAt(0, scriptmgr);
     }
}

You can dynamically add it to the page as well. First check if it exists and if it does not. Add it as the first control on the form.
