I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?

I have update panel , in update panel i have one button control which exposes onlientClick event ( it dosent have click event to do postback to server).
and i have one updateprogress panel. So my problem is though i'm performing operation on client side , internally the async event is firing and making updateprogress panel to act (having rotation gif image) which i dont want , as it rotates for 10-15 sec more even after the operation at client side is done !

By default the postback of child controls will trigger update panels' update.
How can I avoid the same?

I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I can't figure out how to get the user control to trigger the update panel.
Master

<head id="Head1" runat="server">

I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?

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.

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?

How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page
Custom Control
UpdatePanel
LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.

I use Update Panel in some parts of the page and when the user click on Insert Button, I want to save all the data which is got from the Update Panel's controls. But the data from the Update Panels' controls are not saved in the database. When I debug, the data are in the textbox and hidden field, they are in the Update Panel. But they are not save in the database. Other values, which is not in Update Panel, are saved in the database.
How can I take the data from the Update Panel?
Here is some of code.

I have an accordion control in my web site. And in one of the panels, I have a drop down list box where, when the user selects an item, it updates the labels right below the ddlistbox. I have it so that it maintains the scroll position when the ddlistbox has an autopostback, but it's very obvious that the whole page posts back. My question is, can I/should I just enclose the ddlistbox and the labels (and a couple of text boxes) in an AJAX update panel? I already have a ToolScriptManager (because of the accordion control), so I don't need to have another script manager, right? I can just put the update panel (with the other controls inside of it) right in the accordion panel, right? Then when the ddlistbox posts back it won't have the delay of the whole page posting back? And it'll still execute the event handler for the listbox selection change? Does this sound right? I'm just looking to make the post back "invisible", and I would like to do a partial postback of just these few controls.

I am trying to wrap my head around update tabels, the thing thats boring me is if i should use one or multiple panels. When i load a control into my update panel should that control have it's own update panel? Or will it use the updatepanel it's loaded into? Is it even possible to dynamicly load a control into an updatepanel and do async post backs from there? Let me paint you a picture:

I have 2 user controls. The first user control generates custom paging and assigns the output as a string literal. The second user control is a simple repeater which uses values from the paging control via a query string to decide which relevant chunk of data to retrn.
The custom paging control is embeded in the custom reapeater control. In my my page, I simply call the customer erpeater control and everything works treat.I now want to add update panels to this but I can't think where to start.
The paging control looka like this.
