C#, ASP.NET 2.0, Textbox validation question

I have a web form that has two textboxes on it.  I want to be able to validate that at least one of these boxes is blank before sending the request back to the server.  

If txtbxA.Text = "Something" then txtbxB.Text = ""  or
If txtbxB.Text = "Something" then txtbxA.Text = "" 

I have found ways to validate them to be equal to each other or to be equal to a specific value, but cannot figure out how to validate that one is always blank.

This is probably really easy, and I apologize if it is a stupid question, but I haven't worked much with web forms.  Any help is extremely appreciated.

Thanks

I normally check the length property of the text to determine if a string is empty.
so ( in c#  something like )
if ( ( textbox1.text.length > 0 & textbox2.text.length == 0) || ( textbox1.text.length == 0 & textbox2.text.length > 0 ) )
{
   // ok to proceed
}

I cannot believe that I was so dumb!!!!  That was just too obvious.  Thank you very much for the suggestion.  It works just fine.
