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.
View 4 RepliesI 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...
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 2 RepliesI know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
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).
I have to implement the print functionality on aspx page like on click of print image icon user will be able to get the print out of aspx page .aspx page will contain the server controls like textboxes , Gridview etc which one approach will be the best server side or client side printing ?

View 4 RepliesI encouter some postback issue when using GetPostBackEventReference. Here is the Scenario:I have a javascript modal popup dialog and got a button in this modal dialog which used to select things (this is NOT an asp:button control)
When this javascript dialog HTML button is clicked, it will call the MS AJAX web service call by the javascript: eval() method. And this MS AJAX web service call is dynamically generated. So the code is like this:
var serviceCall = svcCall + "(" + parameters + ")"; //dynamically generate the MS AJAX web service call here
eval(serviceCall);
//use eval to trigger the MS AJAX web service call
As you may all know, after complete the MS AJAX web service, you can define a callback function to handle the completion:
function OnComplete(result, userContext, methodName) {
//force to call postback manually
eval($(userContext[0]).val()); [code]...
As you can see, this is how I bound the asp:button (i.e. btnSelectUser) 's Click Event to the asp:hiddenfield using the GetPostBackEventReference, and set the registerForEventValidation argument to false. I have also tried to use different ValidationGroup and set the CausesValidation to false.In summarize, I bound the asp:button's Click PostBackEventReference(i.e. __doPostback(....)) to the asp:hidden field's Value attribute, and using javascript eval() to eval this hidden field's value in order to manually trigger postback.
p.s. the btnSelectUser is an asp:button control and used to call out the javascript modal dialog.
Ok, here is the Problem:In the same page, there is some asp:validator, e.g. and , and of coz, when the page run into error, this validator and callout will display to the user. e.g. When the user didn't fill in anything and submit the form, the ValidatorCalloutExtender will display a ballon and tell the user. Imagine one of this ballon/validatorCalloutExtender come out and on top of your screen at the moment.
Then you click the btnSelectUser (asp:button) to show the javascript modal dialog, and in the dialog, you Add some users, and once you hit the SELECT button inside this modal dialog, a MS AJAX web service is trigger as mentioned above, and once this web service is complete, it eval() the asp:hidden field's value (i.e. __doPostback(...))......and do the postback manually.
However, because of the validatorCalloutExtender ballon has display, it somehow cannot trigger the postback in this way, but when I close the ballon/validatorCalloutExtender, the manual postback using eval() is just working fine. Even more strange is that, when the ballon is displayed, the first time I click the SELECT button inside this modal dialog it doesn't fire the postback, however, if I do the same thing again (i.e. open up the javascript dialog, and choose some users, then click the SELECT button again). It able to do the manual postback....and I don't understand why the first time doesn't work.
i am added one button on user control it is working fine locally but not working on server my error is CS1061: 'ASP.templates_categories_productsingrid_ascx' does not contain a definition for 'dl_viewall' and no extension method 'dl_viewall' accepting a first argument of type 'ASP.templates_categories_productsingrid_ascx' could be found (are you missing a using directive or an assembly reference?)

View 2 RepliesI have a button where I use an Animation Extender. When I click the button I have to set OnClientClick="return false;" otherwise the Animation Extender closes.
So that causes my problem. How do I execute server side code from this button?
I have tried this code in my code behind, but there is an error:
Code:
Dim strScript As String
strScript = "<script>"
strScript = strScript & "return false;"
strScript = strScript & "</script>"
ScriptManager.RegisterStartupScript(Me, GetType(Page), "MyScript", strScript, False)
This is my code for the Animation Extender:

I want to be able to load a customized log in page depending on a couple of parameters passed into the querystring.Each customized login page needs to be able to dynamically display log in errors and possibly have other variables passed in.
Let's say the dynamic login page looks like this (over-simplification here):
<form>
<% if (has_errors) { Response.Write(error_msg); } %>
<input type="text" name="email">
</form>
If the aspx page loads the file like this:
Response.writefile("path/to/custom/page");
the code shows up in the output and doesn't get processed. I have tried other ways to load the file contents (something similar to classic ASP includes) but get the same results every time.I could have all the custom pages set up as user controls, but I need 100% control over the css, js, and html - and the documentation I read here indicates that I won't have that level of granularity.link textPLUS - I'm stuck in a .net 2.0 environment - so .NET MVC is not available to me

i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click.
using : asp.net web form
i have a web form with few textbox and a gridview control and a button.
if i click on the button i am executing two things
1) asynchronously get data from server to client (working great) and able to display the data in the textboxes.
2) same click i want to bind the gridview.
[Code]....
recap:
1) jquery script execute asynchronously to get data from server to client and display in the textboxes
2) server side code to bind the gridview.
PROBLEM:
if i have onClientClick="return LoadDataById(); then it executes ONLY ajax code and does not execute server side but if have onClientClick="LoadDataById(); then it executes client and server but textbox value wipeout. (the textbox value popuplate through ajax)
