AJAX :: Updating Label In An UpdatePanel / Both Lables Showing?
Sep 2, 2010
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 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>

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 have a server side procedure that opens a tcp socket to a server then recieves chunks of data from the server. The server side code does this in a loop, collects the data as a string, then finally displays the data in a textbox. It all works fine.
My problem is, as the chunks of bytes are returned, I need to update a client textbox or lable showing bytes received on each iteration of the loop. I've tried injecting client side java and I've tried using such things as the updatepanel and/or updateprogress controls. I haven't gotten anything to work. It always seems to only update the client on the last iteration. i.e. in a server side procedure/loop, update a client side textbox/label. Or maybe tell me what I am doing wrong? This is some of the code I am using now without using an updatepanel or updateprogess:

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)

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.

I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.
Whenever I click on a checkbox the click event gets triggered and I make a call to
__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.
is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

I have a user control embedded in an UpdatePanel. I'm trying to display a message on the parent page which contains the UpdatePanel when I complete some work in the code-behind of the usercontrol. It appears that due to the partial postback the event delegates that the original developer used to update the labels with messages don't get updated from calls within the user control. The call to the event delegate is executing and I can trace the execution including assigning the text to the label, but when the page is updated the message is not displayed.
I tried moving the labels inside the user control and therefore within the UpdatePanel and setting up event delegates in the user control page_load but that has the exact same effect.

Explaination in detail I have a tree view control on left of my page and AjaxToolkit:TabContainer on the right,consisting of 9 tabs in it (I have developed individual controls and added to the tab panels). On selecting a value from the tree view control the I am refreshing the values inside all the tab panels. There is a method reload written on all the controls which are called on tree view click which sets the value of the selected tree item in properties in all the controls and also refreshs them. Its a big performance issue for sure which i need to improve on but that would come later.
My problem
1. In the Main tab (ascx control) consists of asp:chart control which I am populating and it also consists of 2 buttons in which ModalPopupExtender would open up another 2 controls on button click within this control. Now on the tree view click I am calling
the reload of Main Tab which internally called the reload function of these 2 controls also
On Tree view click
Maintab.reload
{
ModalPopupExtender1.reload
ModalPopupExtender2.reload
}
Secondtab.reload
Thirdtab.reload
If I populate the asp.chartcontrol without reloading the ModalPopupExtender1.reload ModalPopupExtender2.reload it works great but when I call both ModalPopupExtender1.reload
ModalPopupExtender2.reload it shows up and goes away.
Any thing i am missing on ? How to make chart control stay on the page and not vanish. I tried making it visible again. The main page contains a chart control which comes and goes away and does not stay only if i comment out the reloading of these usercontrols it stays visible with values on the main page else goes away.
2.Performance problem- I am not sure how to lazy load the content inside the tab panels so that controls should have the selected item for tree view click and can populate thereon.
3. This is how I call my user controls to reload on the treeview click from within the main page.
PEGeneralInfoPortfolioProfiler1.PortfolioCode = strPortfolioCode;
PEGeneralInfoPortfolioProfiler1.ReloadControl(1);

I have some code that I am working on that uses an UpdatePanel and some dynamically created buttons to perform functions. The problem is that the dynamically created buttons aren't working the same as my test static button, which is behaving exactly as it should be.
So I was wondering if someone would be willing to simply post an example (in VB.NET or C# please) of the following:
An UpdatePanel has a Label and a Placeholder inside of it
The Placeholder has a dynamic button added to it
Clicking on this button will make the Label say "Hi" without performing a full page postback.
If I can just get that much to work, I am sure that the rest of the code will be fine. I just can't seem to get my dynamic buttons to act like my static ones do in an UpdatePanel.
