AJAX :: Gridview With Newsted Update Panels Slow?
Mar 19, 2010
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 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'm looking for a way to use custom ASP.NET validators to validate input, without using UpdatePanels, and without a full postback. The validators do several things - not just length/regex, but some other non-standard stuff as well. Javascript is required for our users, so I don't have to worry about normal users who have javascript turned off. I see several options, but none are ideal:
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.
3) Use jQuery (or any other javascript framework) validation for client validation, then if they somehow get by that, have server-code validation controls for full postback. This would require all of the validation rules to be written in javascript as well as C#. I don't care about the full failed postback at this point, because the javascript validation would catch real users who weren't trying to screw me over.
Is there alternative out there for using real CustomValidator controls, with partial postback, C# code only, for validating input without UpdatePanels and without a lot of redundant javascript?

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'm using two update panels, and in the Page_Load, I'm calling if (masterPageScriptManager.IsInAsyncPostBack).Is there a way to test where the update came from and only refresh the affected panel?

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 a drop down list that hides a panel with a bunch of controls when a certain value is selected, and shows the panel again when some other value is selected. This works fine. However it's slow when running both on my local webserver and on my web host, and takes about 1-2 seconds. What could be the reason for this? The only thing I do is to check which value is selected and hides/shows the panel.

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?

Suddenly all update panels in my website became unknown elements. They work fine when I run site.
But:
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
But I have this reference already.

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 have, what i think is a very simple updatepanel setup. I have searched and found other similar issues, but they date back to 2008 and 2009. Is the fix provided back then the only known fix now? Is there any other fixes or things.

For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?

I know it's not the best practice to do, but unfortunately I created a page with multiple large dropdown lists and have them inside an ajax updatepanel. I found some work arounds using siderite's ajax updatepanel adapter:
http://fastlistadapter.codeplex.com/.
The performance is very good while I am debugging on my machine, but when I publish the site and post it to a win 2003 server the performance drops off almost as bad as when the fix isn't there.
I understand that using a 3rd party fix really isn't supported by most, but is there any obvious reason why debug performance would be much better than published site performance on the same exact code?

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:
[code]....
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?

I have a page with 2 update panels
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'm using PopupControlExtender in a GridView, which pops up various dropdowns, treeviews, calendars etc. depending on which cell is clicked. I'm populating the dropdowns on the OnPreRender event. The result is, GridView is becoming extremely slow. I've tried removing Calendar controls, the Grid is still very slow. My guess is the enormously large source view of the page, resulting from populating controls on PreRender. Here is a sample ItemTemplate:
[Code]....
My goal is to populate the controls inside popup panel only when that panel becomes visible. I tried using OnResolveControlID event for this in PopupControlExtender. But strangely enough, that event fires only when control is NOT found, contrary to what its name suggests.
Anyway, my goal is to populate the popup panels controls (mainly ListControls) ONLY when their container panel becomes visible - hoping that this will make the grid faster. The same grid works perfect with AutoGenerateColumns=true and no populating of ListControls (not an option). Also, I'm NOT using debug option in web.config.

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?

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:
<form id="form1" runat="server">
<asp:ScriptManager ID="SM1" runat="server"/>
<div>
