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.

We have a web part on which we display some data in a grid. We are exporting grid's underlying datatable to Excel and displaying Open - Save - Cancel dialouge box on click of a server side button.Following is the code we are executing on click of server side button.
this.Page.Response.Clear();
this.Page.Response.AppendHeader("Content-Disposition", "attachment; filename=MyTasks.xls");
this.Page.Response.ContentType = "application/ms-excel";
this.Page.Response.Write("...here goes my well formated html....");
this.Page.Response.End();
Problem is that when i click on Cancel in the diaglouge box then dialogue box to Open/Save excel disappears but all the server side buttons placed on my web part becomes non responsive, on click of any of those buttons their server side click event does not get fired

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?
<asp:Repeater ID="rptrParent" runat="server">
<ItemTemplate>
<li>
<a href="<% =ResolveUrl("~/cPanel/UserView.aspx?User=")%><%# Eval("StudentUserName") %>">

I need to do stuff after my page is rendered in the browser. In detail, i need to send email/sms and other non-browser related stuff, but the operation takes time, and i dont want my visitors waiting 5-8s for the success message.I have tried putting the "After Rendering Code" in the page Unload event. That seems to work - but only on localhost. It does not work on our production server.So i figgured, maybe this is some IIS setting? I've also read that it's up to the browser, if it will show th epage after rendering is complete - or wait for the whole package to end.So i tried to end the package with Response.end before my "A-R-C", but that just killed it.
View 3 RepliesThe scenario is this. I have a long page that has a scroll bar. I'm us an Ajax ModalPopupExtender and that too is very long and has a scroll bar.
The problem I'm seeing is that in IE when a user scrolls the modal popup window, when it reaches the bottom it also scrolls to main window which has a really ugly user experience.
So what I want to do is, through server side code, I want to dynamically change the body css overflow from auto to hidden and I can't seem to find a way to make that happen. I've tried a number of approaches and none of them seem to work.
<body style="overflow:hidden;">
I am using Ajax's EnablePageMethods way to call server side code using javascript. The problem is that in IE8 the page automatically refreshes after the ajax call has been completed i.e. the server side function has been executed successfully. I want the same to happen with Chrome and Firefox but it doesnt refresh the page once the server side function has been executed.

I'm building an application that creates bar code images based on the number of selected rows in a GridView. It counts out 6 bar codes and the corresponding labels, and then it needs to force a page break when my counter hits "6".
How do you force a page break from your server side (VB page-behind) code in ASP.NET?
Can you change the pagestyle from the code-behind? I wanted to try : "pagestyle = "page-break-before:always" - but it was not an option in the intelisense menu...
Currently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.
If I have a standard HTML textbox
[Code]....
but got a readonly error.
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.

View 11 RepliesI 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?

View 2 RepliesI know that I can receive an javascript object from the server via ASP.NET AJAX using Json.

View 1 RepliesSuppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

View 4 RepliesI have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
