AJAX :: Modal Popup Dialog Validation?

Mar 23, 2010

I have a button Import on my page. Upon pressing this button, a modal popup dialog appears where the user can enter path of the import file. I have a required field validator to make sure the user entered the path. And I have there a Submit button. My problem is that validation happens not only when I press the Submit button on the modal popup, but also when I press any button on the page itself, which is wrong.

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.

C# - Client-Side Validation In A Modal Popup?

Oct 1, 2010

I've got a gridview/formview, master/detail relationship going on. When I click a button in my formview (item template), I display an ajaxcontroltoolkit modal popup.

On this popup there is a textbox (several, actually). I want to validate the data in this textbox (at least six digits, so far I'm using a regex validator) before I dismiss the popup.

The validator works, but I can still dismiss the form by clicking OK. What I'd like to do is have the ok button on the popup disabled until the data is good.

I have tried fiddling with some stuff in javascript, but I couldn't make it work, as there seems to be some issues regarding finding controls in a formview.

AJAX :: Modal User Control On Top Of A Modal Popup + Javascript Causes Page Flash

Jul 29, 2010

Modal Popup user control (its a message box) on top of a modal popup with javascript that maintains postback on a scrollable div all inside of an update panel causes my page to flash on postback of the user control. If any one of the peices (user control, modal popup, javascript) are missing everything works fine. The javascript is maintaing scrollback on a scrollable listview on the page. A modalpopup is shown on top of this main page that is for report parameters. The user control is used for validation and is displayed if a parameter is invalid. I know this may not be the best design, but it can't really change unless its a minor change. Heres the js if anyone wants to see popup or styles let me know.

//Begin methods to maintain or reset scroll position during postback.
var controlIds = [];
var scrollTops = [];
//Register a control to maintain its scroll position on postbacks.
function MaintainPostback(controlId) {
controlIds.push(controlId);
}
//Find the div/control id in the controlIds array and set its scroll position to 0.
function ResetControlScrollTop(controlId) {
var index = 0;
while (index < controlIds.length) {
if (controlId == controlIds[index]) {
scrollTops[index] = 0;
return;
}
index++;
}
}............

AJAX :: Modal Popup Using Modal Disappear In Postback

Jan 24, 2013

I look for a good way for arrangement Admin pages Items

for example Admin Upload Page consists of these sections:

* make a new folder

* delete folder

* upload file in folder

* show folders information (in a gridview)

* download test

so I think one way is showing this sections in modal

but when I tried make a new folder in modal after clicking in create folder button modal disappeared.

Is there any way that  modal doesnt disappear until user click close button?

I mean I want modal to behave like a page.

If there isn't a way what to do for classification sections?

AJAX :: Modal Popup Click Control Within Panel Is Closing Popup

Jul 27, 2010

I'm using modal popup extender and panel with calendar in it. Click the "Next / Previous Month" closes the modal popup. How do I tell the modal popup to ignore click events in a calendar control inside the panel targeted for popup? I'm confused because when using extender before, you had to click OkButton or Cancel to close popup. I have update panel for reason. I just minimized the code for easy review.

MVC :: Query Dialog: Modal:true Option Prevents The Dialog From Rendering?

Nov 16, 2010

I am using MVC2 on VS2010 Express edition. I followed a post by Dino Esposito on UI with JQuery passing data to a dialog from strongly typed views. I can't make the dialog work with modal:true option.Here I have a simple page that includes RenderPartial for a dialog. The dialog is supposed to pop up when a button is clicked. However, if I include modal:true as one of the dialog options, then when the button is clicked nothing happens. The dialog does not pop up. When I remove modal:true from the dialog options then dialog pops up as expected and closed as expected.
