Hello jfrade,

You can't change DOM values during a BeforeChange or Changing event. You'll have to put them in the AfterChange event.

May I have help with the following error?

{"Operation is not valid, because of the current state of the object."}

I have one multiple selection listbox which I wish to populate into one textbox field. I loop through the selected items which are nonempty and store into a string. I am getting the above error on the SetValue method. Thanks for your help.

Public Sub Model_ListBox_Changing(ByVal sender As Object, ByVal e As XmlChangingEventArgs)

' Ensure that the constraint you are enforcing is compatible

' with the default value you set for this XML node.

' Write your code here

Dim root As XPathNavigator = MainDataSource.CreateNavigator()

Dim iter As XPathNodeIterator = root.Select( _

"/my:myFields/my:group1/my:group2/my:group3/my:Model_ListBox", NamespaceManager)

Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()

While (iter.MoveNext())

Dim value2 As String = iter.Current.Value

If value2 <> "" Then

sb.AppendFormat(value2)

sb.AppendFormat(";")

End If

End While

root.SelectSingleNode("//my:Model_ListBox_Collapsed", _

NamespaceManager).SetValue(sb.ToString())

End Sub
