Web Forms :: What Is The Slickest Way Of Showing A Visual Image To The User While A Page Is Loading
Jan 31, 2011
I know there are a number of ways to show the user that a page is loading with a visual image.What is the slickest and most effective way of doing that. I would like to use Javascript if possible.Presently I can turn on an image calling a function form pageLoad() method of Javascript, but I can't figure out a way to turn it off. Couldn't get pageUnload() to be called.
How can I show loading image for the user while executing long running process in an ASP.Net Ajax application? Is there a way other than using Page Methods? Any ideas?
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.
I have an asp.net page, with couple of Divs, some of these div's get the image path from database and show the image in a smaller version (thumbnail). and as soon as the user click on thumbnail, I use ajax Modal popup to show the full size image, what I need to have is to have a progress image(gif), on every thumbnail image while loading the asp.net page for the first time, I konw that it is possible to use UpadePanel, but I need the actual working code,or any other way to achieve this,
The above code contains an image tag in header of the master page..
whenever I open a new web form linked with this master page.. the existing image doesn't open or isn't displayed..
And one more ques... the overall contents of the web pages are moving beyond their original locations after being run the program.. whereas the contents are in their own locations before execution.. How can I make them static to view??
Displaying loading gif image whenever my page takes time to load but not for particular single control. i had seen this. URL...but it working for button , can i check it for my whole page and all controls whenever it takes times to load.
I am working on a pretty heavy page in an application and the scenario is:
There is a Tab control in the page, having four tabs. These tabs individually consist of different user controls and other asp controls. Most of these usercontrols in turn consist of other user controls. Every user control contains huge javaScript functions which validate them, populate controls and call web services.
What I am trying to achieve is to load only the Tab and its user controls on the page load and when the user clicks on a specific tab, load its contents (User controls) dynamically. Once that is done, I am setting the tab's postback to false to prevent loading it again once loaded.
I tried to achieve this by making the user controls in the other tabs - visible="false" in the markup and loading them from server side on some specific event. But that causes the javaScript functions in those user controls to give errors ('Object expected') when I go to that tab.
If I set the user controls in the other tabs to visible true, then no matter what; the page life cycle goes to each registered control and loads every subsequent control in that web user control which makes the main page slow (on loading and every postback).
The position of the Tab and the inner user controls is fixed. Although I am taking care that no data is populated unnecessarily on the page and user controls on hidden tabs, I dont want the tabs to get loaded altogether unless requested. If I load them on runtime, their corresponding javaScripts start giving errors.. note that I am not generating the controls on runtime, they exist in the page design. I just dont want to load them dynamically
i have a page it contains a User Control. in it we have a Button "View Tree" it will open a pop up window (contins a tree view).when we select any node in the tree the Corresponding item will be Loaded in the User Control and Close the Popup.i want to achive this With out re loading the total page. i am using VS 2008.
URL.... Still there will be need of url in ajax method if i put javascript in site.master.cs . As what i have understood from that mysite.master.cs will be like this :
In the ASP.NET application that I'm working on, the home/landing page takes around 20-25 seconds to load.
And, that is expectable by everyone, as the application loads huge data, calls multiple services before the first page can be loaded.
I am looking to show some kind of HTML UI to the user while the page loads up.
I tried multiple things but the earliest that something shows up on the page is through Response.Write() in the Page Init and hide that HTML content in jQuery's $(document).ready(). In this case also, something shows up after 60% or the wait time has passed.
I want something to show up as soon as the authentication is done (form the login page) and before the home page shows up. Something similar to what shows up on Orbitz.com or [URL], some kind of UI between clicking search and the actual search result is shown.
If it was ASP.NET MVC, I can think of good solutions as you have complete control on the rendering but we are using ASP.NET 3.5 with server side Ajax controls.
Here's what currently takes place before the home page:
Login page submit actions - Authenticate, Load SSO Data, Redirect to home Page.
So i'm finally done with my project, which is a registration form, a long one indeed, with around 30 validations and fields, all is good. Only problem is that when you submit, it takes some time to process to the thankyou page, in this time, browser loading bar doesn't show that it's loading and nothing indicates that the form is being processed :S
Any way to make browser loading bar show? or like, add a custom progress bar? or can i make the submit button get enabled and show a text saying "Processing..." for example?
i want to show a loading gif while page loading. I am opening a popup window from javascript using window.open. I just want to display an image when mozilla or IE progress bar is being shown as gmail does when we login. I know how to show loading img after page is loaded i want it with the progressbar of the browser.
I have an image control that puts user's photo in it. Once it's loaded, I resize it using the javascript.But the thing is, when the page is loading, the image gets really big, then shrinks down being called by the javascript. Is there a way for me to pre-load the image before displaying it? I do'nt want to set the image control's width and height to fixed pixels at this point.
When I click Submit button in my Registration form it should be open a (div) progress bar Showing processing.... (or) loading and block background.how to display a progress bar loading.... in div after Submit button click??
I have a website with a menu, when menu item is clicked I display the page for that menu in an iframe(iframe is set to display home page initially by default). sometimes it could take few seconds to display the page for the selected menu item (for example reports) and I would like to display a loading image while the page is loading. how to do this using javascript or jQuery
