How To Tweak To Just Show When User Leaves Page And Not When Postback Completes
Mar 13, 2011
I have several functions running on a postback that can take a little time to complete.
When postback is initiated I show a loading image with this code:
function showLoader()
{
document.getElementById("<%=loadingImage.ClientID%>").style.visibility="visible";
}
I want to be able to add code to this function so if user tries to leave at this point they are informed the operation is not complete.
[code]....
how I can tweak to just show when user leaves page and not when postback completes?

I was wondering if there is any way to always run some server side code when a user leaves a page in ASP.NET. The page Unload event is no good because that doesn't get called if someone clicks on a link. Ideally I'd also like the code to run even if the user closes the browser.

I have an aspx page that on a button click creates a BackgroundWorker and then calls the RunWorkerAsync method. In my aspx file I have set Async='true' but when I run the application and click the button it appears as though the page waits to refresh until the processing of the BackgroundWorker is done. How do I get control to return to the page (and have the page refresh) after the BackgroundWorker is created and started?
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += RunJob;
worker.RunWorkerCompleted += JobCompleted;
worker.RunWorkerAsync();

I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?

I'm using javascript alert to show a message to the users.
My code is as:
private void ShowAlert( string message )
{
Page.ClientScript.RegisterClientScriptBlock(
typeof( Page ),
"alert",
"<script type= "text/javascript">alert('" + message + "');</script>" );
}
and it itself works fine i.e. the message box is shown.
But e.g. with Firefox when the user does not immediately click OK-button on the alert message, the page stays dimmed after the alert box has gone. With IE 8 this seems not to happen (or is very rare).

I have to use progress bar with modal popup when page postback. in my application report section is there. it's taking some time to generate the report. so i want to show some progerss image instead of nothing. i used java script and modal popup. here is my code.
<script type="text/javascript">
// var prm = Sys.WebForms.PageRequestManager.getInstance();
//Raised before processing of an asynchronous postback starts and the postback request is sent to the server. prm.add_beginRequest(BeginRequestHandler);
// Raised after an asynchronous postback is finished and control has been returned to the browser. prm.add_endRequest(EndRequestHandler);
[Code] ....

I need to set the pager settings of an ASP GridView to look just like this:
********************************************************************** ******************************************
********************************************************************** ******************************************
Showing 31 - 40 of 500 items Page:<12345678910>
I have edited and tweaked so many attributes, but I have gotten confused. Here is the GridView header as I have it now:
HTML Code:
<asp:GridView ID="OrdersGridView" runat="server"
AllowPaging="True" AllowSorting="True" PageSize="25"
AutoGenerateColumns="False" width="100%"
CssClass="mGrid" PagerStyle-CssClass="paging" AlternatingRowStyle-CssClass="alt" PagerSettings-PageButtonCount="20" ShowFooter="True"
[Code] .....
That gives me the following look:
********************************************************************************** **********************************************
********************************************************************************** **********************************************
I still do not know how to get the records count and things over to the left on the same line. I have them down on my footer in the DataRowBound routine.
The first image I posted in the picture of what I want it to look like, the behavior of the < and the > brackets is to go to the next page not jump to the front or back or anything else.

I have an Ajax auto complete textbox in my .NET 4.0 asp.net page via a web service, but the browser auto complete dropdownlist feature shows up on top of my .net auto complete dropdownlist.
Is there a way to make sure the browsers auto complete feature does not popup on this textbox? Almost like an override to make sure the browser ?

The current panel that is visible etc.I tried a simple update panel without success by setting UpdateMode to conditional and ChildrenAsTriggers to false.

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 asp button and a user control containing custom validator in it when i click the button that is present on the page not inside the usercontrol, the user control client side validation occurs and displays the javascript method regarding data entry failure but when i click the javascript alert box ok button, the postback gets occured automatically i want to stop the postback if the user control contains invalid data in iother words the postback get occured only when the user control contains the valid data.
I have already done this type of coding in javascript:
function CheckTimeRangeTo_9(sender, args) {
var e = document.getElementById('<%= ddTimeTableTo_9.ClientID %>');
var totalToTimeInMins = CalculateTotalMinutes(e.options[e.selectedIndex].value);
var totalFromTimeInMins = CalculateTotalMinutes(args.Value);

to update a part of form before the request completes?for example, I have placed following code in button1_click
lbl1.text = "1"
system.threading.thread.sleep(2000)
lbl1.text = "2"[code]...
so what i want is, lbl1's value should be changed to 1 then to 2 after 2 second and then to 3 after another 2 seconds, rather than waiting for whole procedue completion.i had also tried to write this value to session and try to update these values from timer controlled updatepanel but it turned out that session are sent/set only when whole request is complete.

Alright, I am completely baffled by this one. When filling out this page in IE8, it will SOMETIMES clear all entered data (including radio choices) when you select Yes, No, or Not sure (line 892 in the code). This is a postback question, as it should potentially show more questions. This problem does not happen in any other browser, and rarely in IE8. I have no idea what is causing it, the code I am using has been used in similar applications and I can't find any change which results in this behavior.
The full code can be found here: http://pastebin.com/a12cPzyF

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.
