Hi Viv,

Did you figure it out yet? I just started playing with your example, plugging stuff into the Immediate Window and found a solution for you. Check the Count to see if it's 0 or not in your get:

public string Customer
{
    get 
    {
        if (((IEnumerable<XElement>)content.Descendants("Customer")).Count<XElement>() == 0)
            return "";
        else
            return content.Descendants("Customer").Single().Value; 
    }
    set { content.Descendants("Customer").Single().Value = value; }
}

>This works fine until I set the XMLContent to (again a fictitious example - but assume that it is a valid thing to do) an XElement that does not contain a 'Customer' element. In this situation I'd like the Customer property to return an empty string. If I inspect the Customer property in the debugger it shows an exception - but I can't seem to trap for this situation anywhere (I was thinking I could do this in the Customer accessor....)
