Doing some work after Response.End() (11/14/2013 updated)

I need to do something that after users download a file from my website. Most file downloading approach is using something like this:

//data preparation at here...

Page.Response.ClearContent();
Page.Response.ClearHeaders();
Page.Response.Clear();
Page.Response.Buffer = true;
Page.Response.ExpiresAbsolute = DateTime.Now.Subtract(new TimeSpan(1, 0, 0, 0, 0));
Page.Response.Expires = 0;
Response.AddHeader("content-disposition", "attachment;filename=" + YourFileNameHere + ".xls";
//here I use excel file type
Response.ContentType = "application/vnd.ms-excel";
//FileContent is a string variable which stores your file content
Page.Response.AddHeader("content-length", FileContent.Length.ToString());
Response.Write(FileContent);
Response.End();

Mobile version is on.

Added a mobile version to my blog. If you use your smart phone to browse my blog, it will transfer you to the mobile version of my blog after few seconds.

Tips: Prevent CheckBox from being changed by user

The easiest way to prevent your CheckBox from being changed by users is adding this to your CheckBox's html code:

OnClick="return false;"

For example:

<asp:CheckBox ID="CheckBox1" runat="server" Text="Want a salary increase?" Checked="False"
 OnClick="return false;" />
