AJAX :: UpdatePanel - GridView - DataSource Null - Get The Datatable To Persist Between The Two Update Panels?
Jan 17, 2010
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 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 a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

My problem is that I have tried to update my gridview which is inside my updatepanel but the data in the gridview does not update or change when I change the data in my database.
I have used the basic method of using timer to change the label like this Label1.Text = DateTime and with trigger <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />. Timer is <asp:Timer ID="Timer1" runat="server" Interval="1000" Enabled="true" OnTick="Timer1_Tick"> .
<Triggers>

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'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.

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 am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

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 have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I have a master page that loops through form keys looking for a specific key:

Problem, if I use an UpdatePanel on a page when this code is hit the last form key is null. If I don't use an update panel, all is good. Why does the UpdatePanel send a null form key in the list?
