Hi Ryan,

Welcome to MSDN newsgroup.
Based on your description, my understanding on the question is that you'd
like to let only the validation Summary display the validation error (when
validtion fail.....) if there're both validator control and
validtionSummary control on the web page, yes?

Based on my understanding, the ValidationSummary's error message is just
retrieved from the actual Validator Control which raise the validation
error....   So we can not disable or use the Visible property to hidden the
validator control.  Currently I've tried using the clientside  css style  
"display:none" to hide the validator control's clientside element.  We need
to add the followig code in our page's code behind to register the client
style for the Validator control (which we don't want it to display error
message directly....)

RequiredFieldValidator1.Style["display"] = "none";

Hope helps. Thanks,
