Iis - Run Server-side Code AFTER Page Render & Sending?
Dec 10, 2010
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.
I'm new to writing custom ASP.NET server controls, and I'm encountering the following issue:
I have a control that inherits from System.Web.UI.HtmlControls.HtmlGenericControl. I override the control's Render method, use the HtmlTextWriter to emit some custom HTML (basically a TD tag with some custom attributes), and then call the case class' Render method.
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.
The 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.
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...
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.
I have an asp.net button, that when clicked calls a code behind function. The function does some evaluation, and then I want to call javascript from within this asp.net function.
I 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?
Suppose 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 ?
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?)
I've been using code behind files since day one. Now, I have this funky example that uses inline code. How do I use inline code that needs to be executed in Page_Load() while VS still gives me a code behind page? Do I remove the Page_Load event from code behind file?
I 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: Open data"></asp:Button>
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 want a confirm box from server side code but it's not working
a= a+", "+texbox1.text;
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "confirm", "<script>return confirm('"+a+"'File Already Exists do you want to replace!');</script>");
