If you use a CustomValidator control and a ValidationSummary control within an aspx page for server side validation you can set the ErrorMessage of the validator and its Text value will appear in place and the ErrorMessage value will be displayed within the ValidationSummary control.
Nice.
Now, what if I also perform validation on the client side in javascript, is it possible to perform the same kind of validation message display as if the server side code had fired? So that the ValidationSummary would display its usual HeaderText along with your additional ErrorMessage and the CustomValidator would display its Text value (e.g. *)
I can probably fake it for client side vs. server side but it would be nice to use the existing controls if at all possible.
Thanks in advance for any ideas or suggestions
