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'm trying to prevent data from loading on the page when its needed.
Currently, I check the IsPostBack bool to prevent loading data in my user controls which allows the data to be loaded when the page is initially requested.
However, if my page fails validation and the page is sent back to the user with error messages, my user controls no longer have data in them because the initial request was a postback.
One solution is to have a flag in every user control (IsFailedPostBack) to force them to reload their data. Is there a better way?
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
The problem with my web application is when ever i load the home page - The master page as well as content page loads ---This seems fine but when i navigate thorugh the website which have the same Master page but diffrent content page .... the master page loads again. What i want to do is ..I want to keep the master page intact and only the content page loads. How can I accomplish it..
I have an Ajax form with a single input and a button. On submit, the form should only post the entered value to an action method. My form is correctly posting to the User controller's Log method but when done, the page redirects to /User/Log.
I have a textbox of read only type with jquery datepicker so when the page post backs then that textbox value gets cleared. I do not want the textbox value to get clear but at the same time i need postback the page also..
I have to use progress bar when page postback. in my application report section is there. it's taking some time to generate the report. so i want to show some progress bar.
When page load progress bar should show. and when page load finish the progress bar should hide.
I googled many thing mostly they are using thread.sleep method but i don't want that.
The progress bar should fully depend on page loads.
We have installed a web site written by others which is compiled with Visual Studio 2008 and hosted in Windows server 2008 R2.
The IIS connection timeout is set to 120 seconds. But for some pages, the first page loading fails with HTTP 404 error but sequential refresh can bring the page up. The same problem happens for some images which fail to load in web pages. We are not very sure it is network related issue or hosting issue.
I have update panel on the page to avoid postback and placed a dropdownlist control within that update panel. DrodownList is filled with Category names and also it's autopostback set to True.
Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.
actually this code is working well in firfox mozila but it's not working in IE8

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 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?
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 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> <div>
[Code]....
Is there something I missed out in the documentation? I've been working on this all day without much success.
