I'm using the ModalPopupExtender control from the AJAX toolkit. This control extends a panel which contains a CreateUserWizard control. However, the validation of the CreateUserWizard control causes a postback to the server, which closes the popup. I'd like the popup to remain open, even after the postback.

i have some jquery code that I use to toggle a panel (pnlAddBuilding)
In this panel there is a dropdownlist that does an autopostback. When the postback occurs the panel closes.
How do I keep it open?

I have a page.. which im trying to implement a gridview that allows you to select from it, it will open a modalpopup with a list of records linked to the selection.. now within that popup, you can pick a individual record so you can see full details..So my question is, can you have multiple modalpopup's open at the same time? If not then is there anyway to reopen the first popup with the list again so that you can pick another record
View 3 RepliesI have a simple example of a ModalPopup with a panel that appears in the center of the ModalPopup and a couple of buttons in that panel. One of the buttons is a cancel and the other is an OK button. No matter how many other buttons that I add each one closes the ModalPopup. I need to keep the ModalPopup open so that I can run a few calculations then click a close button.
View 5 RepliesI have a linkbutton 'Forgot Password?' in my login page. On click of the link button a modal popup will open . In that user has to give his username.
If the username doesnot exists i want to show an alert 'Usename doesnot ' exists.
Since the checking for the existenance of the username is on click of the button submit which is inside the modal popup, i can show the alert using the code
Page.ClientScript.RegisterStartupScript(...) . But I want something different
I want to call the javascript function after the maodal popup extender is closed
I have a GridView inside a ModalPopUpExtender and would like to know how I can ensure that I can work on the grid without the pop up closing everytime i click on say 'edit' or 'delete' on the grid items.
At the minute my pop up is working great, then i click on 'edit' on a row in the grid and it the pop up closes, I then click the button to fire up the pop up again and the grid is in the mode i wanted it to be in!
I am using asp.net 2.0 with c#.
i want a pop up to be displayed when user tries to close the browser and if user click on "no" [i.e. he don't want browser to be closed] then it prevent browser to get closed.

I have a collapsible panel extender inside a modal window, my problem is that whenever I click on the link button (to expand my panel), the window closes.
Does anyone know of a way to avoid this?
I have a modal popup that i use to play a video, works great.. but once you close the popup if for any reason you hit the enter key or refresh the page at a later time, it causes the popup to open again. There are 3 buttons within the page that can call this popup, so where within my code behind would i add logic to prevent it from popping up unless you click one of those 3 buttons..

here i want to prevent postback when answerlength == 0 ; but when answer length ==0 then it alert alert("u can't submit blank answer") message and postback to server io want to prevent it how i do ?
Simple one here... is there a clean way of preventing a user from double-clicking a button in a web form and thus causing duplicate events to fire?
If I had a comment form for example and the user types in "this is my comment" and clicks submit, the comment is shown below... however if they double-click, triple-click or just go nuts on the keyboard they can cause multiple versions to be posted.
Client-side I could quite easily disable the button onclick - but I prefer server-side solutions to things like this
Is there a postback timeout per viewstate that can be set for example?
I am a problem with Postback event.
I have a web page (aspx) which takes longer time to load the page. If this page is loading and if user requests same page by clicking menu link again, it is considered as not postback and page starts loading again (as soon as it finished first page load).
I want to prevent this from happening. When page is loading and user requests same page again, it should not process those requests and should be neglected.
This aspx page is requested from menu (which is designed on seperate master page).
I have some validation JS code on client, that must be executed befor PostBack.If this validation code return 'false', postback is needless.How it can be disabled?
View 5 RepliesIn dropdown when i select value(not text) "0" it should not go for postback,
to do this i am using e.preventDefault();
if i select other than "0" it has to go postback.
but,it is always going for postback ,the e.preventDefault(); is not working.
How can i achieve this in jquery?
return false; is also not working.
i am sure that i am selecting the value "0", i checked it by using alert();
I have a treeview loaded with nodes. When I click on a node that is set to .Selected, I want a frame to load with that node's objects. Instead, it appears that the TreeView is posting back and causing the node that was clicked to be lost. For example,setting the below function to OnSelectedNodeChanged causes a NullReferenceException.
Protected Function LoadObject(ByVal sender As Object, ByVal e As EventArgs)
Dim node As TreeNode = tv1.SelectedNode
Response.Write(node.Text.ToString())
I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem
My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs.
I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator.
Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing.
I'm trying to set the where clause on a LinqDataSource object bound to a GridView programmatically on a button click, but when the GridView rebinds data (for instance, when the user sorts) the Where clause resets back to the empty string. Is there a way to prevent this, or is there a better way to filter my results?

This code opens me a dialog box with Ok and Cancel button but it do not wait for user activity and post the page immediately and the label gets populated. I need to call the c# function based on user activity. If user clicks "Ok" label should get populated and if user clicks "Cancel" it should not call the c# function. How do I achieve this?
I am developing an application that manages a photo contest. In that application, I use an AsyncFileUpload control for the user selected photo. The server-side UploadedComplete does basic validation, and scales/clip the image as necessary.
The problem is, when i click on the submit button on the page, the content of the AsyncFileUpload gets sent with the other user-submitted data, so the user gets to wait twice as long to get a response from the server (I'm expecting photos that are between 3 and 7 Mb big, which takes a minute or two to upload).
My form looks like that:
<%-- ... snip - all other fields ... -->
<div style="margin-top: 20px; margin-bottom: 5px;">
<span class="texteB"><b>Upload a photo</b></span><br />
Browse your computer to find a photo.</div>

Is there something I missed out in the documentation? I've been working on this all day without much success.
