How to close jQuery ColorBox on file download

Lets suppose you want to display a custom message in a jquery colorbox before a user can download a file, on clicking an agree button on that colorbox, user should be prompted to download/save/open the file and the colorbox should be closed, use the following steps to do so

1. Agree button event handler on the colorbox page should do this

protected void btnAgree_Click(object sender, EventArgs e)
    {
        Session["FilePath"] = YourCompleteFilePath;//put your complete file path here
        ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "popupclose", "window.location.href='DownloadFile1.aspx';parent.$.colorbox.close();", true);          
    }
2. Page load on the DownloadFile1.aspx should have the following code



byte[] FileData = new byte[0];
            string filePath = Server.MapPath(Session["FilePath"].ToString());
            FileInfo file = new FileInfo(filePath);
            if (file.Exists)//set appropriate headers
            {
                Response.Clear();
                Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
                Response.AddHeader("Content-Length", file.Length.ToString());
                Response.ContentType = "application/octet-stream";
                Response.WriteFile(file.FullName);
            }

Great piece of writing! I am agree with the writer's opinion.
The removal of data definitely directs a person to some sense of discontent.
However for the simplicity of end users, Specialists developed an alternative for data corruption problems.
If a deletion of data problem is occured, person got to know which tool or software package to apply so that he can handle this case of data files loss.

Thank you. Yes its better to be responsive to users rather than relying on them to take some action...
