>Instead of using the Try/Catch approach, would you know if there would be a way to use reflection to know if a property exists in a class?

Something like this:

object dataSource; // The object in question

var prop = dataSource.GetType().GetProperty(boundField, BindingFlags.IgnoreCase |
                                                                            BindingFlags.Public |
                                                                            BindingFlags.Instance);

if (prop != null)
   // The property exists

I (think) the VB version would be something like this:

Dim prop = dataSource.GetType().GetProperty(boundField, BindingFlags.IgnoreCase Or BindingFlags.Public Or BindingFlags.Instance)
If prop <> Nothing Then
   ' Property exists.

You may need to adjust the binding flags, depending on the types of properties you want to check.
