AJAX :: Full Page Postback Using Login Control?

Apr 14, 2010

I'm using an UpdatePanel (with UpdateMode conditional) and in the ContentTemplate I've got a Login control. Even though the control is embedded in the UpdatePanel as soon as the Login-button is hit a full page postback is being done. I've read some posts on the subject indicating that these controls are incompatible - but these posts already date from 2 years ago. Does anybody have more recent information on the subject?

AJAX :: Web User Control Loaded Into PlaceHolder Control Causing Full Postback On Parent Page?

Jun 1, 2010

In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.

When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.

how to capture this post so its rendered in Ajax and not a full post back?

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:

[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?

AJAX :: Mozilla Does A Full Page Postback And Refreshes The Whole Page

Feb 10, 2010

Im implementing a simple form with ajax to warn the user if email has been used or not for registration, and it looks to be working fine with IE but mozilla does a full page postback and refreshes the whole page.

I already tried changing to updatemode to conditional, all the triggers are set as async, etc but mozilla keeps doing the same, Im sure it is a known problem I may not be the first one facing this problem so i guess there is a simple workaround for this.

Drop Down List In User Control Cause Full Page Postback?

Jan 14, 2011

I have the following scenario. I have a page that hosts several user controls. The user controls are all surrounded by a single update panel. All user controls have a save button on them. When the save buttons are clicked the page updates the update panel as expected. Some of the user controls contain editable list views. Whenever an action is taken on these list views, the Update Panel is NOT refreshed, but the whole page posts back. How can I get these ListViews to also refresh the Update Panel? I cannot post the code because of NDA. There are no javascript errors on the page reported by either IE8 or Chrome.

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 :: Modal PopUp's OkClick Causing Full Page Postback?

Apr 28, 2010

I am having issue with my ModalPopUpExtender's OKControlID. I have a button inside an update panel that should do AsyncPostBack. The button works fine and runs server side code but it causes full page postback. How do I solve this issue? I want the 'OK' button inside the modalpopup to call the serverside code and update Label control 'label3' without causing the page flash. Given below is my code;

MarkUp:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Next Gen Web Browser</title>

User Control Inside Update Panel Causing Full Page Postback

Jul 13, 2010

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.

C# - AsyncFileUpload Postback Does Not Do A Full Page Postback?

Jul 6, 2010

I implemented the AsyncFileUpload control on a web page. This web page requires uploaded files to appear in a gridview. The gridview contains the following columns: "File Name", "Confidential" Check Box, and a "Remove" button to remove the uploaded file.

Since the AsyncFileUpload postback does not do a full page postback, I need to "force" a postback on the OnClientUploadComplete event of the AsyncFileUpload control in order to render the gridview after uploading a file. In the OnClientUploadCompleteevent, I use javascript to call __doPostBack. In this postback, I only bind my gridview and display the file information (I don't re-save the file).

The problem: On the AsyncFileUpload's first "partial" postback, the file is successfully uploaded, as expected. On the second postback that I force with __doPostBack, the file is re-uploaded. You can verify this by using Google Chrome, which displays the upload progress. The behaviour is as follows: After selecting the file, the progress increments from 0% to 100% and the file is uploaded. After this, the __doPostBack executes, and you can see the upload progress increment again from 0% to 100%.

How can I make sure the Gridview is properly populated, but that the file is not uploaded twice?

I attached a sample solution which contains the issue:

AJAX :: Full PostBack In EndRequestHandler?

Jan 7, 2010

I have an UpdatePanel with a button that, when clicked, calls a WebService. I attached an UpdateProgress to it that shows a "loading" gif while it runs. Everything works fine, but I need a full PostBack once the operation is complete because I'm using my company's custom template that displays an info message and enables a "Next" button upon completion.I've had partial success with the endRequestHandler but I'm not sure what to put in my function to force a full postback once the UpdatePanel has run its course. I'm getting into the endRequestHandler function but I have been unable to successfully get a full PostBack.Here is my current code (including several attempts), the bottom part being the focus:

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 :: Updatepanel Asyncpostback Triggering A Full Postback

Apr 1, 2011

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:

AJAX :: Timer Results In Updatepanel Gives Full Postback

Jan 19, 2011

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

[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):

[Code]....

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.

DropDownList Always Does Full-page Postback, The First Time It Fires?

Mar 18, 2010

I have an ASP.NET page using the AJAX library. There is a dropdownlist inside an UpdatePanel, which on index changing is supposed to update a different UpdatePanel to modify a grid control.But after the page first comes up, and you adjust the ddl, the entire page postbacks, followed by a (correct) partial postback. After this one time, every other usage of the ddl performs correctly, trigger partial postbacks.

Both the panel and the ddl are being added from code. The UP is Conditional updates and ChildrenAsTriggers = true. The dropdownlist is AutoPostBack true and has an event set up on SelectedIndexChanged.So what is going on? I've tried adjusting every setting I can think of and still the page completely refreshes once, then works fine after that.

Web Forms :: Change Part Of Page Without Full Postback

Aug 19, 2010

I have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript.

Google Chrome To Full Page Reload On Postback?

Sep 27, 2010

I am creating one of my first Asp.Net tools and I ran in to a small bump. Currently I am doing a postback on a buttonclick which does some server-side calculations. The server-side code then uses those calculations to alter the contents of a div. In IE and Firefox when a postback happens, the div updates as expected. However, in chrome all postbacks do a complete refresh of the entire page. What is causing this and is there a way around this behavior?

Update:
ClientSide I have the following..
<asp:Button ID="Button2" Style="float: right" runat="server"
OnClick="S_ButtonClick" Text="Calculate" />

Which calls a method summarized as so.

protected void S_ButtonClick(object sender, EventArgs e)
{
//Code parsing values from textboxes ect.
//Do Some Calculations
//Output Results
outputDiv.InnerHtml = "<h2>Foo</h2><br/>";
outputDiv.InnerHtml += "Bar: " + calcValue;
}

It is possible that when this postback(if I understand this correctly) happens, that it is still fully reloading in firefox and ie, but it doesn't show it. This effectively masks the postback. However, when I test in chrome, any postback completely blanks the page before reloading the state. Hopefully this clears up exactly what I am asking. Also, my C#/.Net usage might be slightly flawed and I am willing to take comments on such.

Lose JavaScript From The Browser Cache After A Full Page Postback?

Apr 22, 2010

I have an external javascript file which I include to my page on the code behind (as seen below).

My problem is, when I my page makes a postback (not partial one), I check the loaded scripts by using FireBug, and I cannot see the javascript file in the list after the post back. I asusmed once it is included to page on the first load, browser will be caching it so that I do not need to re-include it.

What am I doing wrong?
