AJAX :: Update Panels In Website Become Unknown Element?
Nov 6, 2010
Suddenly all update panels in my website became unknown elements. They work fine when I run site.
no intellisense in update panel (no properties appear, no tags, like "triggers")
no ID property when I drag updatepanel from toolbox
VS says that I check if webconfig contains reference to System.Web.Extensions
1) Suck it up and use UpdatePanels. I'm in the "UpdatePanels are evil" group, so I'd prefer not to do this.
2) Without using validation controls, manually validate the fields by passing the values to a PageMethod static method, via jQuery or any other AJAX framework. This would require client and server coding each time I needed to use a validator.
I have a page with 5 buttons on top. I want the area below the buttons to contain an update panel that will display button 1's panel if they click button 1. If they click on Button 2, then I want button 2's update panel to replace the button 1 update panel. Each panel has stuff on it like check boxes and text boxes.
Is there a way to do this? Is there a more efficient way to do this?
i have 3 update panels on the same page with labels that are showing different countdown and i want then to run separate from each other. I've tried to use timer control that triggers each of them separatley with limitations in ontick event., the coutdowns are strating but after a few seconds are stoping and i don't know why.i'm not using scripts. I want to run like those on mafia wars on Facebook when something is done to start one contdown and something else other timer.
I realise that there are many posts on update panels and repeaters but none that quite solve my problem. I have a page with two Repeaters each inside seperate update panels. They sit next to each other one on the left and one on the right. The left repeater is filled from my database on my page load event. Im am storing the data in a List<> and then binding the list to the repeater. This works correctly and displays all my results. Each item in the left repeat has a button aswell. The button needs toremove the data from the left repeater and place it in the right repeater. I only want the database to be accessed in the Page_Load and then never again during the use of the page, until the data is saved (I have not got to this feature yet). So I have decided to use List<> objects.
I have a page that display a record set inside an update panel. There are also a handfull of checkboxes/textboxes that allow filters to be placed. Each checkbox/textbox is set as an async trigger for the update panel and set to autopostback.
If a single checkbox is clicked the whole filter/render process takes roughly 1.5s.
If I check a filter and then several more before the intial postback is complete I get a postback time of somewhere between 20-50s depending how many boxes I've clicked.
I notice (via firebug) when I check a box that triggers an async postback and than another box the original async post back is aborted. And yet it seems like it still executes (or maybe locks?) something on the server.
i have 4 update panels, and 1 of them updates after a button has been clicked, and the other 3 panels contain other buttons, but what i would like to do is that, when the button is clicked, how would i make it ONLY trigger for that update panel, as it updates the whole page, and is affecting my Textbox on the page, which is also in an update panel. how i could make just that specific panel update, and not all of them?
I have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.
I have two different repeater control which are in two different Update panel.I want to bind one Repeater value with another.But When i am using asyncPostBackTrigger or postbacktrigger it is reloading whole page.
I use four different update panels, that use the same timer as trigger.
1) Will the 4 update panels create 4 different HTTP requests to the server? 2) I'm using 4 different panels as the controls are located in different parts of the page, is there a way of putting them in the same update panel? 3) Is this a good coding practice?
I am going to outline my setup then where i am failing
UpdatePanel1 - Contents : 3 textboxes and AddButton UpdatePanel2 - Contents : 1 GridView and SubmitButton
AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page
I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand
UpdatePanel2 has gridview2.
There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels
The behavior I would like is:
1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.
In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?
I have a update panel on the ASPX page,When thepage loads the content in the update panel shouldnot load ( Update panel should show the Updatepanel progress control) but after page load update panel contents should load . How do i get this efect.
I recently faced an issue with a third-party DLL we use in one of our ASP.NET websites.
When I need to update it, I download a newer version from vendor's website and just replace the binary in the "bin" folder in the website folder. Immediately Visual Studio loses this library's namespace (says the method is not accessible due to protection level). And recently we started getting random "Unable to compile" exceptions from the site, we connect it with the library.
But if I delete the old library from the solution explorer, and then Add Reference to the newer version, everything works perfectly.
Is it a bug of Visual Studio, the library we use or our site? Has anyone ever faced same issue and knows how to fix it?
We use VS 2010, .NET 4.0 on Win7 Pro x64, TFS'10. The project is a VB.NET website (not web application).
Is it possible to use an UpdatePanel that has like a few text boxes, and a search button, and then perhaps another UpdatePanel that has a gridview in it to return the results of what was searched. When the user clicks search it hides the boxes, and displays the gridview. Can I do this with UpdatePanels? I am using c# for my coding. Or should I be doing this another way?
I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.
As far as I understand UpdatePanels, they should be invalidated separately, i.e. triggerring one UpdatePanel should not touch the controls of the other panel. It does work so for controls outside of any UpdatePanels, however those which are inside ANY UpdatePanel are touched by triggering ANY UpdatePanel:
i have the below page and i am racking my brain as to why when i have two update panels do they both get post backs. i can tell cause i have two user controls- one in each panel and they both fire page load events when only the left panel should be posing back and updating itself... or else whats the point of update panels if in reality the entire page is posting back!
