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.
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?
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.
<script runat="server"> Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Dim strFirstName As String = DirectCast(GridView1.FooterRow.FindControl("txtCompanyName"), TextBox).Text() If e.CommandName = "Add" Then companiesGridViewSDS.InsertParameters("CompanyName").DefaultValue = strFirstName companiesGridViewSDS.Insert() [code]...
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> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js" type="text/javascript"></script>
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?
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:
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.
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.
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" />
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.
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.
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.
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.
How can I use double buffering in asp.net C#?I want smthng like that : I dont want full page refresh when I click a button in a web page.. I think it can be solved with double buffering. When a button clicked for redirect a content page (button-in master page), current page will not go until the redirected page completely load in the background..
I have a created a form using a user control. One of the dropdownlists in the form is populated after the user makes a specific selection from another dropdownlist...i.e. a dependent dropdown list. This is triggered using the SelectedIndexChanged event handler on the controllling dropdownlist.
The dependent dropdownlist gets populated correctly, but when I choose one of the options and go to submit the form, the dependent dropdown list is reset and doesn't maintain the selection that was made.
The controlling dropdown list ID is "level". The dependent dropdown list ID is "EnrollmentSize".
The "EnrollmentSize" DDL only losses the option that was selected. The DDL is sitll populated with all the correct values. It only losses the option that was selected and goes back to the first option...i.e. "Select..."
The viewstate on the page is enabled and all the other form values are maintained. It is only happening with the EnrollmentSize ddl.
I've set breakpoints and tried debugging and I do see that the EnrollmentSize.SelectedValue is an empty string, but I don't see why or where that is happening in the button click event
I thought it had something to do with EnableViewState,but that is set to true and has no bearing. Everytime I try to submit the form, the "EnrollmentSize" DDL is reset and doesn't maintain the option that is selected.
I've two SqlDataSources and two Repeaters, each repeater contains one hyperlink (i also tried using web server button and anchors). The hyperlinks fetch from the database some values and in the NavigationUrl property I use a string.Format method to create a parameterized url, to pass for the browser, then second repeater is populated according to the value passed in the url which is originally passed by the first repeater's hyperlink. this is my sample code : [URL]
I have only a textbox in a page. If I type something inside the textbox and click carriage return key (Enter), the page refreshes and the textbox becomes blank again.
What is actually happening here? Why the page refreshes? Is it the default property of asp.net?
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.)
I got strange behaviour here. My environment is VS.Net 2008 Team server and I tried to use updatepanel but failed.
[Code]....
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.
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot 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 MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
