I have a problem trying to retrieve a return value from a javascript function and using it from my code behind. The problem is after I call my UpdatePanel.Update() method and call return, I can't continue as I have ended execution of the page by calling return. Please find an example of my code:

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 ?

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
i have a panel out of update panel.i have to make it hidden while navigating through different tabs,i tried these codes
Panel1.Attributes["style"] = "display: 'none';";
Panel1.Attributes.Add("style", "DISPLAY:none;");
I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.
<%
if (Model.HasRSVP(Context.User.Identity.Name))
{
%>
<p>
You are registered for this event!
<%:
Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"})
%>
</p>
<%
}
else
{
%>

View 1 RepliesI 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.

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).

I have .aspx page methods with return type of string, which work great. I am using some jQuery ajax, and some .NET Ajax "PageMethods.methodName" syntax from the client side to successfully call these page methods. I need to return xml from a page method.... I would LOVE to be able to return system.Xml.Linq.XElement type from page method. I get a serialization circular reference error when I attempt to return XElement or XDocument. I don't really want to return XML.ToString() to client, and then convert string to xml in javascript. What return page method return type(s) would allow me to retrieve xml with jQuery ajax call? I know json is the alternative, but will not give me what I need this time.
