<p>I have a grid row containing two columns: one with a label ("phone:") and one with a value (the phonenumber column from a data set). I want to hide the row if there is no phone number. I think I just need some very basic correction to my syntax for the visibility expression. Here is what I am using (which doesn't work).</p>
<p> </p>
<p><em>row["vendorphone"].value.toString() == ""</em></p>
<p> </p>
<p> </p>
<p> </p>
