Conditionally Trigger A Full Page Postback From A Link Button Inside Update Panel

Nov 29, 2010

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.

AJAX :: Update Panel: Need To Trigger A Partial Update For Any Event?

Mar 18, 2010

I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?

Web Forms :: Trigger AJAX PostBack With Panel Click?

Mar 13, 2011

I have four server-side panel controls that, when clicked, trigger some jQuery animation. I'd like them to also trigger some AsyncPostBack as well. Is there an easy way to code that server-side? I know that the Panel controls don't have a Click event.

I could always trigger the AsyncPostBack via JavaScript, but that seems less than ideal.Secondly, (and I don't think this is possible), right now I use a QueryString and cookie to track a PreferredCampus selected. We'll be migrating this to be a subdomain. There's no way to change the URL without full-page postback, correct? What I can do is change the cookie setting via the partial-page PostBack I'm describing above, and then have the subpages catch and redirect to the correct subdomain.I'd really like more information about the first part.

Nov 22, 2013

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.

AJAX :: Update Panel Doing Full Postback?

Oct 20, 2010

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.

AJAX :: Refreshing Update Panel Through Javascript Postback?

Mar 17, 2010

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.
