View 4 RepliesAJAX :: ListView Refresh With New Data
Apr 8, 2010I have a ListView and Calendar on the same page. When somen selects a day on the calandar, I want the ListView to be refreshed with new data. However, when I go through the Calendar_SelectionChanged nothing happens until the next page refresh. The function does execute as I have verified through debugging. Going through the code behind everything looks fine, but the ListView just does not change. I can put a timer on the page with no code, and the ListView will not refresh on the calendar event, but does refresh when the timer click event occurs.
View 2 RepliesAJAX :: Timer Control Forces All UpdatePanels On The Page To Refresh?
Jun 21, 2010I am using a timer control on one of my updatepanels in the asp.net website.
my problem is that behind the scenes the postback is a full postback, therefore any content that is placed under any other UpdatePanel is refreshed, as well.
How can i specify the timer functionality ONLY to the specific update panel, leaving other update panels, which do not contain a timer, unrefreshed.

AJAX :: Use FileUpload Control With Partial PostBack To Avoid Page Refresh
May 7, 2015Here is the sample code am trying.
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional">
<Triggers>
<asp:PostBackTrigger ControlID="Button1" />
[Code] ....
This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.
AJAX :: Refresh ListView After Async File Upload?
Jun 23, 2010I'm trying to combine nested listviews, updatepanel and asyncfileupload, but have run into some problems. I'm having a main listview listing some projects, and in each project I have a nested listview listing some images in that project. I also have an insertitemtemplate, for inserting new images. This template contains an asyncfileupload control. Everthing is contained in one large UpdatePanel, to enable smooth editing of the images and their associated information.
Problem 1:
The fileupload is complete now, and the file uploads as I expect. In the AsyncUploadCompleted event I'm also inserting the uploaded image to the database. So far so good. But when the upload is done, I want to be able to see the newly updated record in my nested listview. But this is not the case. I'm not able to DataBind the listview in the AsyncUploadCompleted, because that throws an exception saying "The control collection cannot be modified....". So, how do I manage to do an async update of the nested listview, showing the new record?
Problem 2:
When deleting items from my nested listview, after the async update the listview shows up without any items except the InsertItem. The items are not removed, a refresh of the page brings them back. Why is the databinding lost during the async postback?
AJAX :: PreRender Code For Control Inside Update Panel Delays Page Refresh
Mar 3, 2010I have a control on a page. In the control's pre-render event I'm executing some code that's taking about a minute to execute. This means the whole page is unresponsive until the control's pre-render event is finished executing.I tried putting the control inside an update panel, but it doesn't matter the rest of the page still won't render until the pre-render event of the control is finished executing. I've attached a very simple example of my code (The event that's slowing up the control's pre-render event is not Thread.Sleep(1000):

AJAX :: Page Inside Update Panel Doesn't Refresh The Session Object After Postback Of Any Control
Oct 1, 2010I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

I'd like to be able to refresh certain items within userControl1, from userControl2.

View 1 RepliesAJAX :: Refresh Part Of A Page?
Oct 22, 2010I've built a page which has an update form, and above that, a photo (based on the same edit). The photo is loaded based on the selected table row being edited.
On this page, I've got a button that opens a modal in an iFrame and allows the user to update just their profile image (all works fine). But when the modal is closed, I'd like to reload JUST the photo (and not the entire page), as it will have changed.
How should I go about doing this? I assume I'll need to use some Ajax controls?

Refresh A Control On The Master Page After Postback?
Apr 12, 2010What i am trying to do here is to show a couple of validation messages in form of a bulletlist, so i have a Div on my master page containing a asp:bulletlist. Like this:
<div>
<asp:BulletedList ID="blstValidationErrorMessage" runat="server" BulletStyle="Disc">
</asp:BulletedList>
</div>
When i then click the Save button from any of my pages (inside the main contentPlaceHolder) i create a list of messages and give this list as datasouce like this:
blstValidationErrorMessage.DataSource = validationMessageCollection;
blstValidationErrorMessage.DataBind();
The save button is located inside an updatepanel:
asp:UpdatePanel runat="server" ID="UpdatePanel" ChildrenAsTriggers="true" UpdateMode="Conditional">
Nothing happens, i can see that the datasource of the bulletlist contains X items, the problems must arise because the Save button is inside an update panel and the elements outside this updatepanel (master page controls for example) is not refreshed.
So my question is, how do i make the bulletlist refresh after the postback?
