I have a label that simply says "Note: * = required fields".  In addition to that I am using a RequiredFieldValidator control to display messages in a ValidationSummary control when the user submits an error (e.g. blank in a required field).  What I'm trying to do is hide the label when the validation message appears (and then vice versa when the erro is cleared).  Right now, both are showing, but I only want one. Any ideas?
Here's a simplistic version of what I'm trying to do.  Again, when the user leaves the textbox blank, a validation error should occur. At that time, the label should be hidden and the validationsummary message should show. Then (vice versa) when the error is cleared, the label should be displayed again and the validation message will hide.
Showing and hiding the validation summary message already works. How do I get a procedure to run to hide/show the label when the validation occurs?  Or is ...
