title: How can I use a Modal Pop Up control in ASP.NET similar to a WinForms Message box?
body: <p>I am building a form, where required field validation must have been checked. I am not using asp validator. I am using JQuery validator like </p>
  
  <p>function checkRequiredInputs(){</p>
  
  <pre><code>$("#frmSaleSubmissionInfo").validate({  
      rules:{
          txtFName:{required: true},
          txtLName:{required: true},
          txtAddress:{required: true},
          txtPhone:{required: true}
      },
      messages:{
          txtFName:"Enter Name",
          txtLName:"Enter Name",
          txtAddress:"Enter Address",
          txtPhone:"Enter Phone Number"
      }
  });
  </code></pre>
  
  <p>This is my client side validation. I am using c# in my code behind page. Now if I turned off allowjavascript option in my browser, as far as I know it won't allow javascript. So I am also doing server-side validation for required field. But, since ASP.NET does not have a message-box control, I am having trouble to let the user know what field he is keeping empty. Is there any way to use a control like the message box to show or let the user know what field(s) is/are required to fill the form successfully? </p>
