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?

I want a browser to go full screen as soon as my page loads. Is it possible in javascript. I know the shortcut key for this F11 but requirement is on page load only.
After reading the solution provided below. I achieved full screen but here i got a trap. I was using timer to make my page postback to get fresh data after every 5 second. And here I found after every 5 sec new window opens up but I want full screen to go only once and next time content gets refreshed there itself.

We have a wfc layer that wraps the business classes and database access and use a client that lives on the database layer. Amongst our group we are attempting to form standards. Some want to have the client call the web method and pass the page they are requesting and the page size. Pass that to the database and then page in SQL Server use RowNum.Some want to cache the full list of objects in http cache on the service tier and page in memory. They concern here is memory use on the server.
Which would be best for a medium number of users with potentially large number of records to manage (say 30K) Is it better to cache them all in memory and work from there or page at the database as the application scales?

I'm using a Ajax SliderExtender in a UpdatePanel. I set a BehaviorID and call $find('behavorID').add_valueChanged function in the $document.Ready. Everything is fine but when I press F5 and refresh the page, I lose the slider in a 1/3 (wtf) chance. If I set var slider = $find('behavorID'), it recognises slider is null.

I wonder if I have any other method but a hidden field to post a JSON object to the server on full postback.
Imagine you have a form (with textboxes, checkboxes, etc) and you need to post a json string when the user post the form. This means, I would post all the form values + the json string but I can't come up with any solution but a hidden field.

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:

why when I create a checkbox using HTML.CheckboxFor the values remain after postback where as if I just create a simple HTML checkbox in HTML after postback the value is no longer there?
What is the difference between HTML.Checkbox vs. an HTML checkbox? Why does one retain the values after postback and one does not?

As part of the deployment, we need to have a maintenance page displayed for our web site. The issue we are experiencing is that when the maintenance page is active and ISA rule is configured to redirect to the maintenance page. We see the following behavior:
The user is not displayed the maintenance page, but is displayed a splash page with the English and French buttons. Click on any button displayed a 404 error regarding the URL / File not found. After clearing the local cache and reloading the browser, the maintenance page is displayed successfully.
The same behavior is noticed one we have disabled the ISA rule for the maintenance page and re-enabled the ISA rule for the the Website. The user is presented with the 404 error and once the cache is deleted, the user can see the Website.The issue is a cause by browser retrieving the website pages from the cache and not directly from the webserver.

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 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'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 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" />
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.

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.

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 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>

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.

This is likely a n00b question, but I can't seem to find any info on how to solve it. Here's the scenario:
I have a Textbox and a RadioButtonList in an UpdatePanel, both with AutoPostBack turned on (they need to be, can't turn it off on the text box))
The user enters some text in to the textbox, then clicks one of the Items in the radio button list.
Because the textbox post back is executing, the radio button is losing the value that the user selected.
How can I workaround this?

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.
