Lets say the CCs are Titled/Tagged "Condition" and "Value." The "Condition" CC is a dropdown with the display entries "meets" and "exceeds" with the values 0.25 and 0.75. The "Value" CC is a plain text CC.
If you mapped the to CCs to a CustomXMLPart to nodes named "Condition" and "Value" then you could use:
Code:
Private Sub Document_ContentControlBeforeStoreUpdate(ByVal ContentControl As ContentControl, Content As String)
Select Case ContentControl.Tag
Case "Condition"
ContentControl.XMLMapping.CustomXMLPart.SelectSingleNode("/ns0:CC_Map_Root[1]/ns0:Value[1]").Text = Content
End Select
End Sub
