AJAX :: UpdatePanel - UpdateProgress Only Displays On Initial Postback?
Jul 30, 2010
In a nutshell I have an UpdatePanel with an UpdateProgress item, first postback checks for warnings, if there are any they will be be displayed to the user as a JavaScript 'confirm' box. If the user clicks OK the next postback occurs to commit the change.
The UpdateProgress loading notification appears on the first postback but not on the second, even though both of them function correctly. The buttons that trigger both postbacks are async postback triggers in the update panel, and both are inside the ContentTemplate.
I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.
I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..
It seems UpdateProgress will be displayed covering the entire area of the UpdatePanel. I want to replicate this behavior using plain javascript, as this behavior needs to be done for a windows client form. Are there any javascript libraries available? I am using a Browser control inside windows client form to get results and render them.
I am using UpdatePanel and UpdateProgress on my webform. On my page_Load, I am checking some of the session variable if thats null then I have to redirect to my other page. Now, as I have updatePanel, we cannot use Response.Redirect so I have this code to redirect to my other page after checking that session variable.
[Code]....
But the problem is that my page continues execution after this line. I want to immediate transfer my page to this other page just like Response.Redirect but it keeps executing and redirects at last. If it comes to this line of code, I immediately want to redirect to my other page.
I want to trigger two Async Postbacks at once using UpdatePanel's via their associated buttons such as the example at the end of [URL] When you click the first button, then immediately click the second button, the first button's message never gets updated. By clicking the second button, the first async Post back seems to be cancelled. Why does this happen?
I saw this article about only allowing one postback to occur at a time here: [URL] Is this the desired behavior for Multiple update panels? Can only one run async code at once? What's the point of it being async if you can't do multiple at once? Here's what I'm trying to do overall: I want a webpage where I click a button which causes C# code to search a certain webpage and parse it. Based on the parsed information, it should automatically start searching multiple other webpages. All the while, I want the web UI to be updated with the progress.
Button Press and the client UI says "Searching..." Then the webpage is found so I want to display "Parsing..." Then the webpage parsing is complete and multiple other websites are searched at the same so the UI will display:
Then when the Webpage 1 -3 are done updating, they change their progress message to Complete. I just started looking into ASP a few days ago and I have two ideas how to approach this problem: zy first idea was to use UpdatePanels and UpdateProgress because they seemed easy to get in there. However, the part of updating multiple webpage status messages at once doesn't appear to be possible since I can't have two UpdatePanels updating at the same time to make changes to the client UI. The one that is started second takes over the processing and the client UI isn't refreshed until that second asynch postback is complete. Ideally, there would be a way to refresh the UpdatePanel's mid postback............
at last project i need to deploy cascading dropdownlist without using web serive or cascadingDropDownList Extender
i try to do this using updatepanel :D this work , but at many times that apear my computer and my internet Explorer as busy and hang and i can not do any thing untill populate the second dropdownlist :(
is there any way to avoid that and to view a wait message until populate the second dropdownlist , i mean is there a sample code for doing that
Anyone knows how to do this? I have three distinct updatepanels on my page, and they're all unrelated. If possible, I would like the user to be able to interact with the other updatepanels while one is refreshing, or at least show which one is refreshing by only covering this with a div+animated gif.
I have a wep page. Its consists of some controls along fileupload controls. My page Fully placed into UpdatePanel. when i press the submit all contols values and file upload file should be stored into back end.i used vs2008 framework 3.5.
Note: for fileUploading perpose i should write trigger with postback on submit button.while processing the submit button action i want to show some processing (progressing) controls like round rotation like..shall i place on ajax toolkit 4.0 instead of 3.5.
I have a problem with an amimated gif inside an UpdateProgress which is linked to an UpdatePanel. Basically the gif displays for a few seconds then justs stops and then a few seconds later the page displays. Reading some other posts it and putting in some debug info I can guess it is because the postback is returning a lot of markup, so it seems the postback has stopped and the gif freezes while the markup is being sent/being rendered. Is there anyway to keep the gif 'running' while all this markup is doing its thing?
I'm trying to put a updateprogress into a webpage where selection from the dropdownlist causes postback. Works out well except that on the first postback, the gif image shows on the leftside rather than on the center. On succeeding postback, it will show on the centre where I intend it to be. Below is my code:
One thing I really don't like about Updatepanel is that I have to rebind almost all components in the page.
For example, I have to specify Eidit (Update) index (for inline editing) after rebind Listview using Update panel (after partial update).
It was too much job to rebind all components, so I redirected to same page and used Querystring to pass values in order to avoid all components to be updated based on one value...
If I update Listview using Updatepanel, the datapager has to be updated as well based on new Select SQL statement results.
Listview is pretty simple to update, using "Listview1.bind()" does the job.
Datapager is also in updatepanel, but it won't rebind with new results.
After post back, I'm still getting same Datapager as the orignal SQLDataSource.
In orger to "refresh" Datapager, what do I need to do??
I used to use iframe to do partial page update, but I'm having big problem using Updatepanel since simple rebind won't do the job.
I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
1. Button_openPanel will display panel Step2Panel through ModalPopupExtenderStep2.
2. Button_runThread (inside Step2Panel) will close Step2Panel and will then run a lengthy process server-side. This lengthy server-side process will cause the UpdateProgress control to be displayed.
Similar to the ModalPopup, I want to disable the whole page while the UpdateProgress control (with its animation gif) is running. Currently, the UpdateProgress is displayed, but I can click Button_openPanel (or anything else) which will cause the application to break.
Is this possible?
This is basically all the code. I stripped anything that was unneeded:
[Code]....
The code-behind is basically this:
[Code]....
Everything's working pretty good now, but I need to disable everything while the time-consuming process is running and UpdateProgress is displayed.
I was thinking of displaying the UpdateProgress control as a a sort of ModalPopup, but I'm not sure if it's possible. If not, then the alternative would be to disable Button_openPanel while the time-consuming process is running and UpdateProgress is displayed.
I'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,
I want to show the UpdateProgress on page A when a user clicks on the "Next" button to go to next page. The next page is Page B, which has heavy data loading. When the button is clicked, it doesn't show the UpdateProgress. What's missing from this code, and how can it be made to show?
I have 3 UpdatePanels on my page, and 1 UpdateProgress. I'd like it to be associated with 2 of the UpdatePanels but not the third one. The AssociatedUpdatePanelID property only allows for 1 ID, so it's one or all of them. Is there another way?
I'm looking for the easiest possible way to hide an UpdatePanel while waiting for the submit response to come back. Stuff like described here - using Ajax Control Toolkit and the UpdatePanelAnimationExtender is both overkill and causing some issues, namely:
Because there are a couple of hidden panels in the page it gets all messed up and hides the wrong panels. I have no idea why this is happening; I can't find a way to specify that only one button is supposed to trigger the animation. I did specify a in the UpdatePanel, but it seems that is ignored and all the controls inside the panel trigger the animation. A simple javascript solution would be ideal. The problem here is ASP.NET likes to generate weird IDs for the controls at runtime. Any solutions for that?
In my aspx page I have UploadFile, Button and a Gridview. I have embedded all controls in Updatepanel control but upon selecting file in UploadFile control, Upon click of the button UpdateProgress text message does not work whereas without using Updatepanel it works very fine. What could be the reason? and solution for this.
I have a nested child and parent UpdatePanel. The problem is, when the child UpdatePanel is refreshed/posted, the UpdateProgress in parent fires up. How can I prevent this? The structure is like this:
I use updatepanel and updateprogress in my project. Whenever I add updatepanel to a page, then I should add updateprogress too. Now I want to make a custom control that include both updatepanel and updateprogress. If there are any controls like this, give me its link. On other hands How to make a custom control likte that?
I have encountered a weird problem that does not exist in Firefox or IE. I have a user control that has a text box and a required field validator. When the user control is hosted in an update panel, the UpdateProgress tag never closes the first time that the UpdateProgress is triggered on the page when the page is viewed in Chrome. Has anyone else encountered this, and if so, is there any solution other than removing the validator? I could manually validate, but who wants to do that to support a browser bug?
