When user click a button the system query from DB, made the zip file and it will be downloaded.
Problem is that after the download i wanted to delete the file from the server.
But After Response.End() no further processing done and cursor is not coming to next line of code where this File.Delete line is calle.
When my Application face a long-time process, i.e fetch a query (SELECT a, b, c FROM d)This query needs 10 seconds to be completed in the MSSQL Management Studio, but when the ASP.NET application try to fetch it, it refuse to return any response to any other requests made on that Server.
I am hosting my Application on VPS Server with good specifications, and I am giving this example the (SELECT a, b, c FROM d) just to tell you the issue, it can be any process, maybe processing a movie, or even fetching some data through external API that is experiencing some slow-down,or whatever.
I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive processing occurs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs.
How do i show a message in this case, that the processing is still going on and ask the user to wait.
I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page ?
We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?

I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
I have written simple HttpModule. context.Response.Output.Write is working fine. but not context.Response.Write().

I have a webpage that reads data from an external source. It can take awhile to retrieve the data.I was wondering if someone could give me an idea on the best way to have this happen in the background. I would like the page to come up and display 'Processing' (or somthing like that) in the panel where the data will eventually be displayed.I thought of the BackgroundWorker component, or maybe an AsyncPostBackTrigger... not sure if these will even solve the problem to my satisfaction.
