Hi, why you don't create a button to sign your form with that, you can easily modify other field on your form.

Is it possible if I am submitting to a SharePoint library.

I have a form that needs to be signed by someone from 5 different groups. I am trying to promote some information into SharePoint about if a group has signed the document or not.

Example:

Group 1: signed

Group 2: not signed

Group 3: signed

Each group will have a different section on the form to sign and I would like for a hidden check box to chck / uncheck as a signature is added or removed.

I have found this code, but I'm having problems with the boolean value and can't seem to get it to work.

if(e.Operation == XmlOperation.Insert)

booleanValue = true;

if (e.Operation == XmlOperation.Delete)

booleanValue = false;

xnDoc = null;

field1 = null;

As you might be aware, the Sign event is not available on InfoPath Forms Services. Why do you use this flag ? Perhaps you can do some check if your form is sign or not on the submit and modify your field consequently.

I'm sorry if this sounds like a dumb question, but I am just learing how to program.

I was under the impression that for a browser enabled form, I was only able to use the Changed and Validating events.

Please let me know if I'm wrong. Thank you for the time.

Ok, how do you create your event handler ? I think you create it with the field signature that's why you can't modify some field. I suggest you to create a new event on sign and try your code on it.

Thank you for your response.

I am trying to sign a section, not the entire form. The field is on the form, not the section that is being signed.

Hi, do you have enabled signature on all the form or just on specific data group?

If your field is on a sign data block, you can't modify it because if you do that your signature will be invalid. You can create a new field on a data block that is not sign or deplace your current field to another xml location but if you have lots of form create with that template, I don't suggest you to do that, you're old form will not open because of the xml structure is not the same that your new template.

I'm sorry if this has been answered before, but please let me know where I can find the answer.

I am trying to change a field after a signature is added to a form.

Getting: "InvalidOperationException was unhandled by user code", "Operation is not valid, because of the current state of the object."

Code:

public void InternalStartup()
    {
      EventManager.XmlEvents["/my:myFields/my:signatures1/my:signatures2"].Changed += new XmlChangedEventHandler(signatures2_Changed);
    }  

    public void signatures2_Changed(object sender, XmlEventArgs e)
    {
      // Write your code here to change the main data source.
      XPathNavigator xnDoc = this.MainDataSource.CreateNavigator();
      // MessageBox.Show(xnDoc.OuterXml.ToString(), "Main Data Source XML");      
      XPathNavigator field1 = xnDoc.SelectSingleNode("/my:myFields/my:field1", this.NamespaceManager);
      if (field1.MoveToAttribute("nil", "http://www.w3.org/2001/XMLSchema-instance")) 
        field1.DeleteSelf();      
      field1.SetValue("true");
      xnDoc = null;
      field1 = null;

Thanks in advance.
