I have added two update panels to my page. I’m trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.

Code

<asp:ToolkitScriptManager runat="server" ID="ScriptManager" />
  <asp:UpdatePanel ID="updatePnl" runat="server" UpdateMode="Conditional">
    <ContentTemplate>

       <asp:label ID="NoConsignments" runat="server" ForeColor="red" />
       <br />
       <asp:TextBox ID="StartDate" runat="server" />  <asp:TextBox ID="EndDate" runat="server" /> <asp:Button ID="Dates" OnClick="btDates" runat="server" Text="Search" />
       <asp:calendarextender ID="Calendarextender2" targetcontrolid="StartDate" Format="dd/MM/yyyy" runat="server"></asp:calendarextender>
      <asp:calendarextender ID="Calendarextender3" targetcontrolid="EndDate" Format="dd/MM/yyyy" runat="server"></asp:calendarextender>
   </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="Dates" />
    </Triggers>
 </asp:UpdatePanel>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
    </ContentTemplate>
    </asp:UpdatePanel>

I’ve left out some of the middle code of there is alot. If you would like any more code please let me know.

Am I missing something? or is this not the way that update panels should be used?

Thanks you so much for any help you can provide

    I haven’t used UpdatePanels for a while, and you haven’t included the mark up for the validators in the second panel.

    However it looks to me like you might not be adding groups to your validation see this tutorial

    e.g.:

    <body>
  <form id="form1" runat="server">
    <div>
      <asp:TextBox ID="TextBox1" runat="server" ValidationGroup="First"/>
      <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
             ValidationGroup="First" ErrorMessage="TextBox1 should not be blank" 
             ControlToValidate="TextBox1"/>

      <asp:Button ID="Submit1" runat="server" ValidationGroup="First"
             Text="Submit 1"/>

      <asp:TextBox ID="TextBox3" runat="server" ValidationGroup="Second"/>
      <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" 
             ErrorMessage=" TextBox3 should not be blank" 
             ControlToValidate="TextBox3" ValidationGroup="Second"/>

      <asp:Button ID="Submit2" runat="server" ValidationGroup="Second"
             Text="Submit 2"/>
    </div>
  </form>
</body>

    Hope this helps and I haven’t missed the point.
