    How to check from onclick if RequiredFieldValidator failed?

    Hi,

    I have a OnClientClick script assigned to a button. From the script, I'd
    like to check if RequiredFieldVa lidator attached to a textbox on the page
    has failed. The Page_IsValid works fine with - for example - regex
    validator but it does not work with the required field validator.

    Any suggestions will be appreciated.
    Thanks,
    Bogdan

      Hi Bogdan,

      Please try the code below to check if page is valid or not in client side
      script.

      <head runat="server">
      <title>Untitl ed Page</title>
      <script type="text/javascript">
      function ConfirmSave()
      {
      if (Page_IsValid )
      {
      return confirm('want to continue?');
      }
      else
      {
      return false;
      }
      }
      </script>
      </head>
      <body>
      <form id="form1" runat="server">
      <div>
      <asp:TextBox ID="TextBox1" runat="server"> </asp:TextBox>
      <asp:RequiredFi eldValidator ID="RequiredFie ldValidator1"
      runat="server" ControlToValida te="TextBox1"

      ErrorMessage="R equiredFieldVal idator"></asp:RequiredFie ldValidator>
      <asp:Button ID="Button1" runat="server" Text="Button"
      OnClientClick=" return ConfirmSave();" UseSubmitBehavi or="False"/></div>
      </form>
      </body>

      Regards,
      Manish

          Manish,

          Thanks for the reply. Unfortunately this does not work for me. It actually
          illustrates the problem that I've been having - i.e. Page_IsValid is true
          even when the text box is empty. So, regardless of the content of the text
          box I always get the 'want to continue?' message box.

          Does this example behaves differently on your system? If yes, what browser
          and asp version do you use?
          I tested it in IE, FireFox, and Safari with asp 2.0 on the server.

          Thanks again,
          Bogdan

              Hi Bogdan.
              I have the same problem. I got around it by initializing Page_IsValid to
              false on the page. It is maybe not the best and cleanest solution but as far
              as I can see it works.
