How To Prevent Master Page Postback When Update Panel Asynchronous Postback Happened
Oct 15, 2010
When an asynchronous postback happened inside update panel, another postback happens also for MasterPage not only update panel embedded page .
I want to prevent this MasterPage postback .
is this possible ? think like i have a MasterPage
and another page which is test.aspx which is content page of MasterPage
i have update panel at test.aspx
when asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Load

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

Is something like this possible?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
I am new to the concept and feel like there must be something really easy that I am missing.

It works fine in Firefox but in IE 7 fails doing the postback sometimes. Is it just a problem with my browser? The partial postback inside the update panel works great in both browsers, but when I hit the button outside the panel, the complete postback doesn;t work in IE....
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="PruebaPostBack.aspx.cs" Inherits="Administrator_Treatment_PruebaPostBack" %>

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.
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

i have some jquery code that I use to toggle a panel (pnlAddBuilding)
In this panel there is a dropdownlist that does an autopostback. When the postback occurs the panel closes.
How do I keep it open?

I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.
The update panel looks like this:
[code]....
So far, I have tried adding an async postback trigger for the user control, which does cause an async postback but does not update the rest of the text in the update panel. In otherwords, the async postback occurs and the next page shows up, but the original text in the repeater is there as well just below it.
I have also confirmed that I have IDS set on my linkbuttons, since that can trigger a full postback inside an update panel.
I have tried changing the update panel mode (Always, Conditional, ChildrenAsTriggers, etc.).
None of it makes a difference - the only thing that actually causes an async postback is to use the trigger, but then the rest of the content in the update panel is not updated, so I get duplicate content.

How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page
Custom Control
UpdatePanel
LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.

I 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 am checking to see on the form if they answer No to question one then go to comments. On the client side I added autopostback="true". So when the page reloads the random number in the label is updating to a new number. How can I avoid the random number not to be updated when the page post pack to itself?
Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load
Dtetxt.Text = Date.Now
F()
End Sub
Private Sub F()
Dim _r As New Random()
Dim n As Integer = _r.[Next](5)
' Can return 0, 1, 2, 3, or 4
Label2.Text = n.ToString
End Sub

Related to my previous question which is answered. The deal is, there is an update panel for modalpopup extender that is triggered by a button. The problem is when the form is submitted by a button, this modal popup is seen on the page! I do NOT want this modal popup extender to be seen when the form is submitted.

I have a page on which there is a textbox that is in update panel and has text changed event and autopostback=true. On the same page there is a 'Retrieve' button(inside repeater control) outside the updatepanel. Now what is happening is if user inputs data in the textbox and clicks retreive button page_load event is firing twice which is not what should be happening, one time its the partial postback due to the text changed event and second time is the page post back. I would like to restrict the second postback.

i am using the update panel in my application in that i had added 3 dropdownlists,all of them are having the selectedIndexchange event so, once you select any item in the dropdown list i had to some operation, but the problem is that if i change the any dropdownlist in the update panel all the dropdownlists selected index methods are getting called, but what i was expecting is that when i select any item in first dropdonwlist that corresponding selectindex has to be executed not the other ones, so anybody had experienced this kind of problem let me know?

I am having an issue with an update panel, which is still causing the entire page to postback.
I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.
I am using a master page, but the update panel only appears in the content page, within the content tags.

I am a problem with Postback event.
I have a web page (aspx) which takes longer time to load the page. If this page is loading and if user requests same page by clicking menu link again, it is considered as not postback and page starts loading again (as soon as it finished first page load).
I want to prevent this from happening. When page is loading and user requests same page again, it should not process those requests and should be neglected.
This aspx page is requested from menu (which is designed on seperate master page).

In one of my webpage, I have a parent window where i have a datalist with 10 rows of images. when i click any image a pop up window(child window) opens.
The child window has a form to be filled by user. Once user fills this form, he will press the save button. Once the save button is clicked, the child window should be closed and the datalist(in the update panel) in the parent window should be refreshed.
This is how I am trying to achieve this. On click of the save button a javascript function is being called of the parent window like this: window.opener.refreshDataList();
in the refreshDataList() function I have written the following code:
{
childWindow.close();
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
This works like a charm in Internet Explorer. However in Mozilla and Chrome it doesnt work. While testing this I added an alert statement ind the refreshDataList() function like this..
{
childWindow.close();
alert("Testing");
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
Once I added the alert statement, It started working in both mozilla and chrome.
So I realize that It could be an issue related to focus. I have done window.focus()
but still its not recieving any focus and not working in Mozilla and Chrome.
