AJAX :: Update A Label On Parent Page From UpdatePanel?

Jul 2, 2010

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.

AJAX :: Use Dynamically Created Button To Update A Label In An UpdatePanel

Mar 9, 2010

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.

AJAX :: UpdatePanel Conditional Update OnLoad Event / Updatepanel To Update On Queue?

Aug 25, 2010

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.

AJAX :: UpdatePanel Doesn't Update Another UpdatePanel?

Jan 20, 2011

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.

AJAX :: Using A User Control's UpdatePanel.Update() From A Page-level Update Panel's Function Call?

Jul 14, 2010

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.

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]...

AJAX :: TreeView Does Not Work With The UpdatePanel In .NET 3.5?

Mar 16, 2010

I have read several post on the TreeView is not/partly working with the UpdatePanel, but none of them mention that an update (triggered by a timer) causes creation of multiple javascript functions in the HTML header. In Mozilla Firefox this a memory leak. I have created a test webapplication to demonstrate the issue we encounter.

AJAX :: UpdatePanel Won't Append Data From Web Service To A Label Control

Apr 1, 2010

I have an UpdatePanel with a button and a label. Inside the button click event I call a web service which returns a string. I then want to append that to the label. Simple! Except that it doesn't work. I can change the label to a value I set inside the click event but when I try to add the web service string it doesn't work.

I have been trying to override the PreRender event, to use a ViewState, to set EnableViewState on the Label to be false. Nothing. Works. At All. If I set a break point inside the OnPreRender override I can see that lbl1.Text is being set to the value that I want (i.e. the value from the web service) but it doesn't appear on the browser.
