SharePoint 2007/3.0 Group By AJAX

Scenario

• Modifying the SharePoint 2007 GroupBy functionality when groups are collapsed by default
• HtmlFiltering content within one of the groups
• Using HtmlFilter prior to 11/19/09 release

Issue

• When expanding a group, the contents are messed up or never display  (loading ... )
• This is caused by a strange implementation of AJAX on Group By fields within the SharePoint List Web Parts


• Normally the UpdatePanel syntax is pipe-delimited with


• length|???|???|content


• The middle 2 parameters seem to be UpdateType and ID




• But the SharePoint syntax is


•  lengthOfEventValidationString|eventvalidationstringcontent||content
• the second and third pipes || are located together between Icon="icgen.gif and " OType="0" within the table tag
• ??? Let me know if you can think of any logic for this syntax ???

Resolution

• Upgrade to the newest HtmlFilter.vb release which will account for the SharePoint Group By syntax

Fiddler was the key to fixing this bug.
