//Main Page - aspx

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'm having a bit of an issue in my ASP.Net application moving focus from a textbox in one user control to a text box in the next user control on the page after postback. I've searched high and low over the last several days to find a solution but, for whatever reason, have been unable to do so.
I have a page that has user controls loaded dynamically to allow a user to enter data.The number and type of user controls loaded to the page is determined at run time based on a database query.It is possible than many controls of the same type can be loaded. Each user control has its own update panel. Within the update panel of each control is a regular asp panel. Inside of the regular panel there are at least 2 server controls (any other controls that may exist in the user control are not affected by this issue) - a text box and a button.The defaultbutton property of the regular panel is set to the ID of the button within the user control. The desired behavior is to allow the user to enter data into the textbox on one user control hit enter to save the data on that user control the application will set focus to the textbox of the next user control on the page after the data from the "current" user control has been saved. Other considerations;
The application uses master pages. We make extensive use of ajax and the ajaxtoolkit in the application. I am using Visual Studio 2010 and .Net 4 The issue - when first entering the page, one can enter data into the first textbox and press the enter key. Data from "current" user control is correctly saved and focus is correctly moved to the next user control on the page.
Data can be entered into the textbox of "new" user control and when the enter key is pressed, the data is correctly save. The focus appears to move correctly to the next user control on the page.Data cannot be entered into the textbox of the control. Pressing the enter key will not save the data (because none was entered) but the focus will move to the textbox of the next user control on the page.
Data can be entered into the textbox of the user control. When the enter key is pressed, the data is correctly saved and the focus appears to move correctly to the textbox of the next control on the pageBasically, steps 3 and 4 are repeated until the end of the user controls on the page, alternating between being able to enter data and not. Other items of note When one is able to enter data into the textbox of a user control, one can correctly tab through the textboxes of each user control until the end of the page When one is not able to enter data into the textbox of a user control, pressing the tab key will take the focus to the address bar of the browser.
I created a much simplified example of the scenario described above and was able to consistently reproduce the "bad" focus behavior. All of the ajax toolkit controls and code where stripped out of the sample to rule the toolkit out as a cause. The behavior still occurs without the toolkit.
I am including the code for default.aspx and WebUserControl1.ascx.

I have a button is inside a another table(s) inside the update panel.

<Button>

I would like to add a button to Update panel's trigger. But am getting an err says "Update panel can not find the button which trigger it".
I am getting "Sys.Webforms.PageRequestmanagerParseErrorException: This message recieved from manager could not be parsed. Common cause for this error are when response is modified by response.write"
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.

I have a gridview.The Gridview is in an update panel.I added a dropdownlist in a template column of the gridview.I have autopostback set to true.I have code working in the selectedindexchanged event all of that works great now I want to add a javascript confirm prompt on client-side change of the dropdowns,I have it popping up the confirm box, but no matter what the user selects (ok or cancel) it does not post back
<asp:DropDownList ID="ddlWinnerStatus" runat="server" CssClass="winStatusDDL" OnChange="return ShowWarning(this);"AutoPostBack="true" OnSelectedIndexChanged="ddlWinnerStatus_OnSelectedIndexChanged"></asp:DropDownList>
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 have a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
I have four server-side panel controls that, when clicked, trigger some jQuery animation. I'd like them to also trigger some AsyncPostBack as well. Is there an easy way to code that server-side? I know that the Panel controls don't have a Click event.
I could always trigger the AsyncPostBack via JavaScript, but that seems less than ideal.Secondly, (and I don't think this is possible), right now I use a QueryString and cookie to track a PreferredCampus selected. We'll be migrating this to be a subdomain. There's no way to change the URL without full-page postback, correct? What I can do is change the cookie setting via the partial-page PostBack I'm describing above, and then have the subpages catch and redirect to the correct subdomain.I'd really like more information about the first part.
