ClientScript.RegisterClientScriptBlock(this.GetType(), "Validator", "<script language=javascript src='js/jquery.validate.js'> </script>");

UPDATE 2

this is the render name by asp

<input name="ctl00$ContentPlaceHolder1$txtLayerName" type="text" id="ctl00_ContentPlaceHolder1_txtLayerName" class="txtLayerName required" />

Answer 1

jquery validate using the NAME property of html inputs, not the ID. it’s been a while since i used webforms, so i don’t know if the name and id match. but it might be worth looking into.

EDIT: i’ve added validation on the fly with great success like so:

    $(function(){
       $("form").validate(); 

       $('.txtLayerName').each(function () {

            //add the required validator to these!
            $(this).rules('add', {required: true});

        }); 
    });
