Event Handlers not firing in Tasks webpart

Asked By: Anish Jolad Date: Jul 06, 2007 Category: Sharepoint Views: 975

I have set up an ItemUpdating Event Handler as a feature for the
Task List(set the templateId to 107 for the tasks list). It fires
when I go directly to the task list and edit a task item. However, I
have added the tasks webpart to the main page which has a link to
each task's display form(DispForm.aspx). When I click Edit Item from
this DispForm.aspx to the edit item and save, the ItemUpdating event
does not fire?

Has anyone ever run into any problems with the event handler not
firing from the webpart that surfaces the list??

The url of both places is similar.. the only thing different is the
source query parameter...

server/sites/siteName/Lists/Tasks/EditForm.aspx?" target="_blank" rel="nofollow">server/sites/siteName/Lists/Tasks/EditForm.aspx?
ID=2&Source=http%3A%2F%2Fserver%2Fsites%2FsiteName%2FLists%2FTasks%

I worked through this problem. It ends up that I have to move my
code to the ItemUpdated event because the new changes to the task
were not saved in the ItemUpdating event. I was trying to use
properties.AfterProperties.ChangedProperties to access what has
changed. When I used ItemUpdated the changes were already saved in
the Content Database and accessible.

Also, a side note that when using ItemUpdating or ItemUpdated the
properties.AfterProperties.ChangedProperties or the
properties.BeforeProperties.ChangedProperties collections are
sometimes empty when there are changes. Here is the msdn link to the
bug: http://msdn2.microsoft.com/en-
