Scenario:

• Notify specific users upon the change of any field in an infopath form excluding a limited number of fields.
• InfoPath Full Trust Form
• SharePoint designer Workflows

I’ve seen lots of people ask for this, with a lot of  the same general response:

it’s not really possible to maintain field-specific change history, or field-specific alerting

I think that Solution 2 below could address this.

Solution 1:

set up rules on every field in the form to set “NotifyParticipatns” to 1 on change.

Pros:

• No code required

Cons:

• Lots of rules and room for error

Solution 2:

Global event listener for all xml fields.  Note the XPath selector used for registering the Changed event handler:

"/my:myFields/*"

Conditional for which fields should be included / excluded from the alert.

Set the “NotifyParticipants” based on conditional result.

 public void InternalStartup()
 {
 EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading);
 EventManager.XmlEvents["/my:myFields/*"].Changed += new XmlChangedEventHandler(Form_Changed);
 }

<br data-mce-bogus="1">

public void Form_Changed(object sender, XmlEventArgs e)
 {
 // Write your code here to change the main data source.
 List&lt;string&gt; AlertableFields = new List&lt;string&gt;();
 string ModifiedField = e.Site.Name.ToString();
 AlertableFields.Add("my:Street");
 if( AlertableFields.Contains(ModifiedField))
 {
 Debug.WriteLine("Alerting on " + ModifiedField );
 }
 else{
 Debug.WriteLine("Not alerting on " + ModifiedField );
 }
 
 }

 

Pros:

• Much cleaner solution

Cons:

• Code.
• Full Trust
