[Code]....
In my webpage I have an updatepanel and a button that updates the Label.[Code]....
[Code]....
If the button is inside updapanel, nothing happens when I click the button (Label is not displayed), but if I move button outside the panel it works. (Button must be inside updatepanel and ofcourse no PostBackTrigger)

In this page, i have 2 WebUserControls called WUCLeft is put into "left" and WUCRight put into "right"
[Code]....
WUCLeft has a button to load WUCRight into "right" ContentPlaceHold
[Code]....
[Code]....
WUCRight has one TextBox, one Button and one Label, when I click Button, the text of TextBox is assigned to Label
[Code]....
[Code]....
The problem occurs after I press Button on "left" ContentPlaceHold to load WUCRight.
In the first, I click on Button on "right" ContentPlaceHold, nothing happens (the Text of TextBox is not assigned to Label). In the second, i click on Button, page is submitted and all control in "right" ContentPlaceHole are cleared.
What did i do something wrong?

I have an UpdatePanel on the page which I'd like to trigger using javascript.First of all my code perfectly works if it's in a website not being inheriting from a masterpage. Now when you put exactly the same code into a website which inherits from a masterpage, the UpdatePanel wouldn't get fired anymore.
Here's the code (.aspx) [Code]....
Here's the code (.cs) [Code]....

firstly,i am going nuts with this problem. here it is:
i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.
now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to
see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.
i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage

i have a Masterpage with a Header, a Footer and a Main Placeholder.
In the Main-Content-Placeholder i use an Update-Panel.
A Problem occurs when i make some Ajax-Action (like updating a textbox) inside the Update-Panel:
The Ajax-Behavior is OK but the footer in the Masterpage is not rendered anymore.
For Testing purposes i put the Footer Elements in the Header of the Masterpage. Then the elements were rendered.

I have a DateTime in my MasterPage.aspx that is outside of UpdatePanel1. There are two Hyperlink controls inside UpadatePanel1 to navigate or to move to the other pages. Full code of MasterPage.aspx is below.
[Code]....
If the user clicks Hyperlink to navigate or move to the other page, the DateTime will change. It means that my MasterPage.aspx render the whole page when the user clicks Hyperlink. I do not want this behavior. I want my MasterPage.aspx only render the ContentPage and the
Hyperlink inside UpadtePanel1. Controls outside UpadtePanel1 like DateTime should not be rendered again. Please advise the code to achieve my example goal.

I have a very simple application that works almost all the time. I am using an UpdatePanel. My script manager is configured to enable partial rendering. My UpdatePanel is configured for conditional update mode. My asynchronous trigger is a timer that runs every 3 seconds. I track unhandled exceptions in the database. I am not getting any unhandled exceptions. Nor am I getting managed exceptions. Now, I had two users side by side running the application today. I had one record in the data queue. The first user did not get updates; her grid did not update. The second user did get updates. The only difference was that the first user was logged in for a long period of time. The second user logged in just before the test. I reviewed the IIS log file and both users were polling the page every 3 seconds for the same data. So why didn't the first user's grid update? The code follows.
<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="30" EnablePartialRendering="true"></asp:ScriptManager>
[Code]....
In my code behind I have the following timer logic. [Code]....

I have a couple of dropdowns inside an Ajax Update Panel. When I try to rebind the controls or set the selected index of the drodowns inside the panel, they don't respond.
For example, I update the database records and need the dropdowns to display updated data. I set the data source for the dropdowns, rebind them and update the UpdatePanel, but it still shows the old data.

this is my first post in this forum, even though I often search for helps and clarifications over its threads. And many times they are definitely useful!!I had a <asp:ScriptManager> in may MasterPage, wich was used to manage various UpdatePanels I have either in Content pages or in MasterPage.Today I inserted a CalendarExtender, so I had to replace the ScriptManeger with the AJAX ToolkitScriptManager.
At the beginning it seemed to work fine (the calendar pop up and others controls got updated properly). Then I noticed that the nodes in various TreeView are not expanding any more. The TreeViews objects are placed inside an UpdatePanel, in order to expand each node without refreshing the whole content page. And, while a node expands, an UpdatePanel containing a GridView in the content page gets updated.Now, with the new ScriptManager they do not expand, but when clicking on a single node the GridView is updated properly.Here some pieces of code:

Controls registered as triggers.I know I can use only one script manager per page,

I am creating a web part, which is loading an ASCX file. This ASCX contains an Updatepanel and linkbutton inside the update panel.
When i click on the link button for the first time, there is a request going to the server, but the UI is not getting updated. and if you click on it for teh second time, there is not even the request going to the server.
I tried using a button also, but there was no luck, the results were same, first time request fires, but the UI is not updated. and the second time even the request is not fired.
I have put the code for both below. i am using Sharepoint 2007 and My master page contains a Script manager as well.

I have an updatepanel with a radiobuttonlist, which looks like this in my markup code:(also, I tried specifying the AsyncPostBackTrigger with the specific eventname "OnSelectedIndexChanged" - no succes either).
[Code]....
In code behind, loads of things happends. But the primary important thing is this method which is being called:
[Code]....
Now, in each postback this is set as a datasource (it is not loosing its datasource because of some timer).What my problem is: Even though the Page_Load event is being fired and I can see the datasource has changed, the content I see in the radiobuttonlist stays the same!

I develop an ASP.NET web application. The server side receives a stream of image data (JPEG frames as byte arrays).
It should processes them and send the images to the client side periodically.
For displaying these images on the client side I tried to use an approach similar to this described in the post "Improve your Image(s)" (http://steveorr.net/articles ImproveYourImages.aspx) by using an auxiliary ASP.NET page for the purposes of the server side image processing.
When I used a client side button to request the image ocntrol (imgCameraCapture) update with its URL pointing to the processing page (GenImage.aspx, as in the above post), everything worked fine (with exception of the whole page re-rendering on each button event). The image was updated.
For a periodic update of the client image control on the main page I put in an ASP.NET AJAX UpdatePanel andset it to update conditionally by triggering to an ASP.Net AJAX timer (10 seconds) event in order to achieve a partial page update (just the image).
II used the timer tick event handler to update the image by invoking the separate ASP.NET image data processing page there as in the button click event handler. But in the timer tick event handler the processing page was not invoked and the image was not updated.
This is the C# code behind executed in the button clik and timer tick event handlers:
imgCameraCapture.ImageUrl = "~/GenImage.aspx";

I either don't understand or I'm not using AJAX right. I'm running a long report. I'd like to have a label to show the user that the "Report Running", then, that the report has finished. But, when the user runs another report, I'd like to have the label that shows "Report Finished!" to clear so that you don't have "Report Running!" and "Report Finished!" on the screen at the same time. But, the label will not clear???? I get both lables showing. What am I doing wrong?
Here is a sample:
<asp:UpdatePanel ID="UpdatePanel2" runat="server" >
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /> [code]...

I'm using ASP.Net 2008 and C# and Ajax. I have wired up my ajax updatepanel to update the buttons within them in the gridview control's RowCommand event. However, at the end of this event, I call the Response.Redirect(commandArgs[2]); to open either Word or Adobe docs that user selected. And this line of code stops my Ajax updatepnael to update my 2 buttons' enabled properties. I thought maybe there is another way to open docs that won't interfer with my Ajax updatepanel and what will that be?

GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.
I'm new at AJAX (that's my first problem - lol)
I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.

I have the following code -
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" >
<ContentTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl="~/captcha.aspx" /> [code]....
Problem is the lblname1, lblphone1 and lblemail1 do not update on the page with the new values, if I step into the routine I can see the values and a success asssignments but on the page I get NO values. I removed from code the updatepanel and I get the values on page.I also tried conditional updatemode with no success but again I get NO values.

I have a radiobuttonlist control in an AJAX tabpanel, which I would like not to postback whenever the selected item is changed. But I do want to modify the text in a textbox, that is within a separate updatepanel, to be the text of the new selected item.
