JQuery :: Modal Dialog Not Triggered By Control Within Update Panel?
Mar 27, 2011
I have a textbox txtPctDown inside an update panel. On textchanged, a sub is called that does a calculation and puts the result in to a label in a modal dialog. When the text changes, the sub is reached but the modal dialog doesn't appear. if I eliminate the UpdatePanel then everything works fine. I tried with an without using the textchanged as a trigger.
How do I get the modal dialog to appear when the text changes?

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.

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?
At the moment, the only pseudo logic for this I can think of is?
'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)
'Try to find the user control as a child of the update panel

I have a simple table with 5 text boxes, above that i have a dropdown where you make a selection, if there are any records of associated with the selection, then i display in the fields..
A while back this was working, you could make a selection and the fields were within a update panel and they were populated. But im revisiting the pages to make some updates and changes and noticing that the page no longer populates the fields when a selection is made..
Is there anyway to debug the updatepanel? I put a breakpoint in my selectedindexchanged event and my Db call is returning values and the textboxes .TEXT values are being assigned the right values in the code behind, but the fields never show up..
This page hasnt been touched since it was wworking last, so need to see how i can test / debug the update panel to determine what coudl be causing it..

I have an ASPX page with several update panels. They all have their UpdateMode="Conditional".
Some panels are refreshed when the user clicks a button and other are refreshed regularly, with a timer.
The panel refreshed with a timer launches a database query and many validations on the data. Then display the result in a panel when errors have been found.
That all works fine except when the validation has to delete files on the disk. (.txt, .jpg, etc it depends). In that case, after the validation is made, I am always kicked out of my website because of the error (Thread was being aborted). So I loose all my session variables which means I am not logged off.
Anybody had that kind of problem ? Is it normal that deleting files AND directories on the server make me loose my session? Is there a way to prevent that ?

Currently I have a project where I have a form in ASP.NET that needs a look up service. For example the input below wants a Customer ID, but maybe the user only knows the customers by name.
<input name="CustomerId" type="text" id="CustomerId" />
I'd like to use jQuery UI's modal dialog to append an image to the right of this input, which fires dialog("open") containing the necessary code to look up a customer by name, returning the ID back to the form input upon closing the dialog. This is extremely similar functionality to the Datepicker's icon trigger found here: http://jqueryui.com/demos/datepicker/#icon-trigger .Right now, I have this javascript:
$("#CustomerId").dialog({
autoOpen: false,
modal: true,[code]....
I need to be able to pass the ID of the input element into jQuery, probably using the $(this) selector somehow. I'd like to be able to re-use the same code for multiple elements on the same form that require the customer ID look up. I also don't know how to create this kind of functionality inside the ASP.NET environment because it doesn't fundamentally allow more than one form inside one .aspx page.

I have a application that contains a gridview. When a user selects one of the items from the gridview, I want to be able to show a jQuery dialog box that contains a form with some pre-filled information from the selected item from the gridview. Right now I have a div with some html text boxes that is set to be a modal dialog box. The user clicks on it, and the selected item's ID is easily to retrieve. The problem comes when I want to go out to the database, get some of the details, then pre-fill in some of the textboxes and other elements before displaying the dialog box to the user.
An easy comparison is having a user click on an item so that they can submit a form to be processed with some of the items from the selection already filled in. I was wondering what the easiest way to go about this is. Right now I have it so that selecting an item from the gridview uses jQuery to do a Ajax post with the ID to a [WebMethod] in the code behind where it can then go off the database and get all the details of the record. The problem is that for obvious reasons the WebMethod can't magically fill in the fields of the form. I could send back all of the information to the ajax query to fill in, but that also feels pretty messy because there is no real strong connection from the random data I send back and which field they belong to.
A lot of this is pondering out loud, but I am really interested in better understanding how to use jQuery and Ajax within ASP.NET.

I would like to have a contact form which contains a reCaptcha, and have that form inside a jquery ui modal dialog.
All works well, except that I have a submit button for the form - which closes the modal dialog wether the recaptcha is valid or invalid.
I tried adding onClientClick="return false;" to the submit button, but it still posts back, and closes the dialog.
how do I remain inside the dialog ?

this is the first time i'm using jQuery dialogs so this question might be somewhat simple but i haven't found answers on this yet.
I'm using ASP.Net Ajax to perform an asynchronous postback when user enters something into a Textbox(actually scanning a barcode). This is working like a charm.Now i need to let the user decide between two options under certain conditions. Therefore i need the postback to decide if this dialog must be shown and what content it has.
Q: How to open a jQuery UI (modal) dialog from serverside, let the user choose an option, postback again to server and handle this decision.
I think i need AjaxControlToolkit.ToolkitScriptManager.RegisterClientScriptBlock to register the script that opens the dialog, am i right? If yes, what script opens the dialog onload?
Can i then postback to server by setting AutoPostback=true on the control(f.e. RadioButtons or a DropDownList)inside the dialog and handling the appropriate events?
What is the best/easiest way to accomplish what i'm trying?
Edit: I considered to encapsulate the dialog into an ASP.Net UserControl and show/hide it. Is this approach recommendable or will it conflict with jQuery in any way?

Is there a straightforward way to use server-side validation with ASP.NET's validation controls in a form that's displayed in a modal dialog? I am using jQuery and SimpleModal (in C#, VS2010, .NET 4.0)I've got a modal form which works fine. I need to use a server-side validation because the logic depends on data specific to the record being accessedMy solution for the project I'm working on now is to use a jQuery ajax call to pass all the form data to the server and get back the validation results before allowing the post to proceed. But this is relatively time consuming to implement, and in some situations I'm dealing with now all the validation code exists already.
The first challenge is that of course the modal dialog will close on a full postback. So you could put an UpdatePanel inside the dialog... without even thinking about this too much, though, I assumed that it wouldn't work out that well. It doesn't. And the form which opens the modal dialog to begin with is already in an UpdatePanel, which further confuses matters.Anyway, I tried putting the contents of the modal form in an UpdatePanel for the heck of it. It does actually do a partial postback, the dialog remains open, but the contents of the dialog do not get updated with anything I change server side. If I close and re-open the dialog on the same page after testing the validation code, though, its contents are in fact updated to reflect these changes. Obviously the way the dialog is rendered is confusing ASP.NET. Or vice-versa. But this just seems sketchy from the get-go.
Rather than trying to hack my way through this problem I was hoping that others had some suggestions about a better way to approach this. Or just tell me I'm trying to hard too mix apples and oranges and I should keep it all client side (or client side + jQuery ajax) if that is the only sensible thing to do.

I have an asp.net button and an asp.net label in an update panel and when I click the button it updates the text of the label in the code behind. However when I try to get the updated value it just returns an empty value.How do I get the updated value after the asynchronous postback has completed. I have included my code below.
<script type="text/javascript">
Sys.Application.add_init(function() {
// Add ajax request handlers

I think my title says it all. I have a modal dialog showing up and the user can make some changes and then click a 'Save' button. I need that to totally post back the whole page. I just assumed the button would fire off regardless of the jQuery.

I have tried searching for the answer but have failed to get any insight into this problem. Look at the following two examples. [URL] (JQuery modal dialog without <input> element) Above pages have very simple JQuery modal dialog, whihc displays correctly in IE, Chrome, Safari and Opera. Unfortunately, Firefox does not display the modal dialog with <input> correctly. It displays the other one correctly. I have tried the following without resolution to this peculiar problem:
- Changed doctype
- Used <table> to enclose <input>
- Used <div> to enclose <input>
- Used all possible CSS display attributes for <input>

I am trying to use confirmation dialog from jQuery UI.
I ran into this problem: how to trigger correctly the dialog and at the same time prevent trigger OnClick event specified at button until user click on Yes or No buttons at dialog?
In the example below are two ways how to popup confirmation. Lower one works well. It's a classic JavaScript confirm dialog. When I try to use the jQuery UI dialog, it displays a dialog but allows it to run the event assigned at OnClick (here by using Command, but I suppose there is no difference. Hope I am not wrong.). The piece is taken from the ASP.NET Repeater control btw.

After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.

I have a modal popup extender which is triggered by gridview onRowCommand. The gridview and the modal popup extender is in different updatePanel. The panel which assigned to PopupControlID of the mpe contains a textbox and a button. This button will triggered a page method web service that will return a value to be assigned to the textbox. My problem is when I click the button, after partial post back, the mpe disapper (hide). I tried everything to make it show. Below is my code.
function Completed(result) {
//get the target textbox inside the mpe
var txt = '<%= txtContractNo.ClientID %>';
var txtRef = document.getElementById(txt);
txtRef.value = result;
var mpeId = '<%= mpeContract.ClientID %>';
$find(mpeId).show();
}
How to make it show after partial post back?
