AJAX :: How To UpdatePanel Does Full Page Refresh Everytime

May 12, 2010

I got strange behaviour here. My environment is VS.Net 2008 Team server and I tried to use updatepanel but failed.


When I clicked the button, I expect Label3 inside updatepanel to be updated and Label2 remained the same, AND of course without page refreshing flick. But the result is page is completed refreshed and both labels are updeted.

AJAX :: UpdatePanel Async Causes Full Page Refresh?

Here is the code. On button click it should perform async refreshing. Instead it does a full page postback.

Updating Div After Full Page Refresh Following AJAX Request?

Jun 9, 2010

I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded.

How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)

AJAX :: After The Upgrade To 4.0 The Linkbutton Causes A Full Postback With Page Refresh?

Jun 15, 2010

I have an update panel with content that needs to be updated by a listview item which is a linkbutton, in .NET 3.5 I just used the defaults on all the controls and everything worked fine, after the upgrade to 4.0 the linkbutton causes a full postback with page refresh. I did try setting the linkbutton's id as the trigger for the update panel and still causes same page refresh. The scriptmanager is on the masterpage with enablepartialrendering = true.

AJAX :: Only One Of 2 Ddl's Causes Page Refresh Within Updatepanel In Detailsview?

Feb 26, 2011

I have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).

Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.

Here's the code:


On Selected Index Change code for each

For the First:


For the Second:

Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel")
Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg")
If ddlModel.SelectedValue = "Add" Then 'Add New Record
txtDDLName.Value = "ddlModel"
txtDtlsViewName.Value = "dtlBikes"
txtItemType.Value = "BikeModel"
txtParentID.Value = ddlMfg.SelectedValue
txtNewItem.Text = ""
lblNewItem.Text = "Enter New Model:"
End If
End Sub

AJAX :: Refresh UpdatePanel At Content Page Asynchronously From Master Page?

Mar 5, 2011

I have master page

MyMasterPage.aspx and content page MyDefault.aspx.
MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into
TextBox1Default1 at content page MyDefault.aspx, and then refresh
UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.

My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008

Below is full code MyMasterPage.aspx.[Code]....

AJAX :: Trigger UpdatePanel Refresh After Page Loads?

Feb 16, 2010

I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.

Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestUpdate.aspx.cs" Inherits="TestUpdate" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> [code]...

AJAX :: Forcing Full Postback In UpdatePanel

Apr 19, 2010

I have basically the following structure set up :


I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :


The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?

We have a fairly complex content management system where we start with a blank page with just an updatepanel, then in the init function add all the controls, this all works fine.The problem I'm having is that when the loginform control logs in, we get data back from the server that looks like:

<span id="ctl00_ContentPlaceHolder1_DEBUG"></span><div id="ctl00_ContentPlaceHolder1_content">
<div class="contentWrapper">
<div class="form">

AJAX :: Timer Results In Updatepanel Gives Full Postback

Jan 19, 2011

I have a quite strange situation where I have the following code:


This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):


When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.

AJAX :: Custom Control In Updatepanel Should Create Full Postback?

Jun 2, 2010

I am searching already the web for some hours to get this working. I created a custom control (ConfigTree), which has a treeview as part of it. I put the custom control into an update panel. So far so good. When I click on different buttons (in ucc:ConfigTree) or the treeview in the custom control an async postback is done. When clicking on a node in the treeview an event for the parent element (ConfigTree) is generated, which populates again an event (NodeSelected) for the parent element (shown below). Different parent elements can handle the event differently. In one element (this one) I need to transform the async postback in a real postback with full page refresh. For better understanding see the following code:


the parent element (here shown) should process the OnNodeSelected and transform it into an full postback and not just an async postback, but only this event, all the other events in the ucc:ConfigTree should processed async. How can I do that? Is there a method to call in the code behind?

I am dynamically ading the following to an UpdatePanel

Tab control which has X# of Tabs, each Tab has a various labels and a Rating Control.

When the user hits the Rating contro, the RATING_Changed fires and runs a stored Proc to update the DB. I want the Panel to then display the newest information back from the DB. I can't seem to get the last part to work. I'm still learning .NET so i may have missed somethign easy, but i've tried setting AutoPopstback, using Triggers, etc.

AJAX :: Child Elements In LinkButton Break UpdatePanel Functionality, Cause Full Postback

Apr 21, 2010

If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.
