I am getting the below stated error in javascript. This error occurs when i try to cal update panel on button click Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.Details: Error parsing near 'Panel|UpdatePanel1| <div id="up'.

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.

I have a composite drop down calendar user control that consists of a textbox and and calendar image and a validation control. I expose a property called "TextBox" on the usercontrol which returns a reference to the textbox used within the control. This is the textbox that the user enters the date into.
In the ASPX page, I have an instance of this usercontrol: [Code]
In my code behind, I want to detect when a user has tabbed off of the textbox and, using an UpdatePanel, refresh an appropriate message depending on the date that was specified. [Code]
OK, When I move athe calendar usercontrol into the Update panel, I get this error: A control with ID 'txtDate' could not be found for the trigger in UpdatePanel 'upIntendedStay'. It's apparently having an issue finding the embedded control even though it's within the update panel, but it has no problem finding a plain textbox that is not embedded within a usercontrol!

I have an update panel that has a table in it with 4 images. Every few seconds a new image is shown. All this works but when the image changes the whole page is refreshed. I am using Visual Studio 2008 and VB.Net 3.5.I only want the images in the updatepanel to refresh. How can I do that?
UpdatePanel Code:
<asp:UpdatePanel runat="server" ID="upImgSwitch" UpdateMode="Always">
<ContentTemplate>
<table height="200px" width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>

I have a problem when updating the source of an ASP ListBox in an AJAX update panel. When I set the source of the ListBox to a large dataset, I would assume it would take a small amount of time to render due to the number of items. However, when the DataSource is switched at run-time to a smaller set of items, it takes just as long to clear it. If you go from a small set of items to a small set of items this is lightning fast. Maybe I'm doing something wrong. I'm using the Visual Studio 2008 item template for an AJAX 1.0-Enabled ASP.NET 2.0 Web Application. I downloaded that from Microsoft.
Here is my code (Full source zip below):

I have a gridview button that I programmatically created and I want to load an update panel on the client side with the sent data. I have a hidden value field that gets its data on the click of the gridview button and the dropdownlist in my updatepanel depends on that value.

url...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.
I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

I would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.
