Here is my situation:

I have two fields (let's call them FieldA and FieldB). If FieldA contains a
value then FieldB cannot, and if FieldB has a value FieldA cannot.

Is there a way using the Validation controls to check for this?

Use CustomValidator. Add handler for ServerValidate event.

Something like this:

private void CustomValidator1_ServerValidate(object source,
System.Web.UI.WebControls.ServerValidateEventArgs args)
{
args.IsValid = ((FieldA.Text == "" && FieldB.Text != "") ||
(FieldA.Text != "" && FieldB.Text == ""));
}
