Accessing HighlightColorIndex in ContentControlAfterAdd event handler RRS feed

  • Question

  • I have C# based Word add-in that is handling the document's ContentControlAfterAdd event. In this handler, I am trying to access the HighlightColorIndex property of the content control's range. However, every time I try to do this I get the following exception:

    'control.Range.HighlightColorIndex' threw an exception of type 'System.Runtime.InteropServices.COMException'

    I can access this property outside of the ContentControlAfterAdd event handler.

    Code looks something like this:

    private void Document_ContentControlAfterAdd(OfficeWord.ContentControl control, bool undoRedo)
     OfficeWord.WdColorIndex color = control.Range.HighlightColorIndex;
     // more code here

    Any ideas as to why this is occurring? Any workaround?

  • Hi 36

    Basically, you can't affect document content while within this event. What you could do is create a Timer that calls code to execute after the event has finished...
