    Ajax with field validator

    How do I prevent field validator which resides outside of UpdatePanel
    from firing off? The label will update correctly without
    RequiredFieldVa lidator via Ajax. TIA.

    Code below....

    <%@ Page Language="C#" AutoEventWireup ="true"
    CodeBehind="Def ault.aspx.cs" Inherits="WebAp plication1._Def ault" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
    www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d">

    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
    <title></title>
    </head>
    <body>
    <form id="form1" runat="server">
    <div>
    <asp:ScriptMana ger ID="ScriptManag er1" runat="server">
    </asp:ScriptManag er>

    <asp:TextBox ID="TextBox1" runat="server"> </
    asp:TextBox><as p:RequiredField Validator
    ID="RequiredFie ldValidator1" runat="server"
    ErrorMessage="R equired" ControlToValida te="TextBox1">* </
    asp:RequiredFie ldValidator>
    <asp:UpdatePane l ID="UpdatePanel 1" runat="server">
    <ContentTemplat e>
    <asp:Label ID="Label1" runat="server" Text="Label"></
    asp:Label><br />
    <asp:Button ID="Button1"
    runat="server" Text="Button" onclick="Button 1_Click1" /
    >
    </ContentTemplate >
    </asp:UpdatePanel >

    </div>
    </form>
    </body>
    </html>

      Re: Ajax with field validator

      You can group the fields via the validationgroup property, although this
      doesn't exactly make sense because if you're trying to validate something
      then it has to be fired with your button that's inside your updatepanel.
      Another possibility is to disable the client-side validation on the
      requiredfieldva lidator. This is good form anyways as you should never really
      perform client-side validation since the validation script can be
      circumvented on the browser.

      Hope this helps,

          Thanks for replying and sorry for late post.

          I resolved it by, like you said, putting and grouping
          validationgroup . The sample I gave was for simplicity. My original
          requirement was to have two drop down lists and have one fire off and
          populate the second one. For example, first one is country and second
          is the state. So on selectedindexch anged from first one, second will
          populate states based on country selection. Thanks again.
