AJAX :: Validation Controls Not Working In Update Panel?

Mar 17, 2010

I am using two update panels in a page. Both of them are conditional mode and display when a checkbox is selected. So far it is good. I have few textboxes in the the second panel and I want validations to be set on those text boxes on a condtion, ie if textbox 1 is not empty then textbox 2 's required field validatior should trigger and viceversa. I have written the following logic in the pageload method,

AJAX :: Validation Summary In JQuery Dialog Modal Popup Box Not Working With Update Panel

Dec 23, 2015

I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:

<script type="text/javascript">
function WebForm_OnSubmit() {
if (typeof (ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) {
$("#validation_dialog").dialog({
title: "Validation Error!",
modal: true,
resizable: false,

[Code] ....

The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added: onsubmit="javascript:return WebForm_OnSubmit();

I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.

When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.

Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.

Here's the markup of the page:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnNew" runat="server" Text="New" />
<asp:Panel ID="pnlEdit" runat="server">
<table>

[Code] ....

So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?

Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.

One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.

AJAX :: Validation Of Controls Only Inside Relevant Update Panel?

Jan 9, 2010

I have a page with three update areas, Create, Edit, and Delete. The controls that do these three functions are inside separate update panels so when I'm doing Create, I only fill controls inside that updatepanel. Problem is I'm using asp validation controls on all the controls in the three areas. Therefore, when I press the "Go" button in the Create UpdatePanel, the validation fails on the empty controls in the other two area. I hope I'm explaining this well. The behavior I would like to see is that only the controls contained in the updating panel would be validate.

AJAX :: Update Panel - Asp Panel Not Working Properly

Jun 8, 2010

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.

I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.

When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.

I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
