AJAX :: Updatepanel Updating - Lblemail1 Do Not Update On The Page With The New Values?
May 6, 2010
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 am having a weird issue with the update panels. I have an update panel in UpdateMode = Conditional . I have a dropdown list and a grid view..the gridview has to be updated ÖnSelectionChanged event on the dropdown.
The issue here is on changing the selection on dropdown, the onselectionchanged event is triggered, new data is grabbed, bound to gridview..but does nt update the update panel even after the updatepanel.update();

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 have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

I have a link button inside an update panel. The problem is the link button on postback is updating the whole page. Tried it with a normal button and the page is not refreshed all. Here's the code.

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.

I have a button that is inside of an updatepanel, I want it so that whenever the user clicks on the button it would update items in the updatepanel and after that it would activate the animationextender but I can't do that as of now because on the button I have OnClientClick="return false;".

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

I am using the following code to update the data in my datagrid.
But when I click update the value is updated in the database but it still shows old value in datagrid.
If I refresh the page after that then datagrid shows the updated value.
Code On Update Command:
protected void MySQLDataGrid2_UpdateCommand(object source, DataGridCommandEventArgs e)
{
string newData;
TextBox aTextBox;
aTextBox = (TextBox)(e.Item.Cells[0].Controls[0]);
newData = aTextBox.Text;
decimal comm = Convert.ToDecimal(newData);
string UpdateHiveCommission = "Update tbl_HiveCommission set Commission = '" + Convert.ToDecimal(newData) + "'";
MySqlConnection objMyCon3 = new MySqlConnection(strProvider);
objMyCon3.Open();
MySqlCommand cmd3 = new MySqlCommand(UpdateHiveCommission, objMyCon3);
cmd3.ExecuteNonQuery();
objMyCon3.Close();
MySQLDataGrid2.EditItemIndex = -1;
MySQLDataGrid2.DataBind();

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 have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

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]...

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?
