  validation summary not generating using update panel

  May 03, 2012 02:50 PM|LINK

  Hi ,

  I made a form that when submit button is clicked the validation summary is shown on DIALOG BOX but AFTER A POSTBACK. i opened it on clicked event when page.isvalid is false.

  now what i want is How i can show dialog box without postback showing summary, i tried to add validationgroup in button but then it wont allow to show dialog box (summary) showing to complete form for that validationgroup to postback

  thanks

  now i tried to wrap up the button in update panel. but it becomes the worst.

  summary is outside from update panel but there is no error messages shown in the validation summary when i wrap the button in update panel when i keep button outside update panel the summary works fine.

  How i can use validation summary with update panel

  Based on your description above, as far as I know, if you are using validation control, you must postback data you want to be validated to the server side every time. Or you need validate the data on client side by using javascript. You also need to postback the data even if you use the UpdatePanel controls. By using UpdatePanel controls, you can refresh selected parts of the page instead of refreshing the whole page with a postback. This is referred to as performing a partial-page update. You just want to show summary without postback, but the inputs of people are different everytime. So the summary is always changed. If I misunderstand you, I hope you follow up and give me more details.

  Works fine from my end, here is what I tried:

  <form id="form1" runat="server">
      <div>
          <asp:ScriptManager ID="ScriptManager1" runat="server">
          </asp:ScriptManager>
          <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
              <ContentTemplate>
                  <asp:ValidationSummary ID="ValidationSummary1" runat="server" ValidationGroup="form"/>
                  <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                  <asp:RequiredFieldValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="TextBox1"
                  ErrorMessage="TextBox cannot be empty" ValidationGroup="form" ></asp:RequiredFieldValidator>
              </ContentTemplate>
              <Triggers>
                  <asp:AsyncPostBackTrigger runat="server" ControlID="Button1"/>
              </Triggers>
          </asp:UpdatePanel>
          <asp:Button ID="Button1" runat="server" Text="Invoke Validation" ValidationGroup="form"/>
      </div>
      </form>

  Hope this helps
