Question

I am using ASP.NET2.0. I have created a download form with some input fields and a download button. When the download button is clicked, I want to redirect the user to a “Thank you for downloading…” page and immediately offer him/her the file to save.

I have this following code to show the savefile dialog:

public partial class ThankYouPage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Clear();
        Response.AddHeader("Content-Disposition", 
                          "attachment; filename=\"downloadedFile.zip\"");
        Response.ContentType = "application/x-zip-compressed";
        Response.BinaryWrite(this.downloadedFileByteArray);
        Response.Flush();
        Response.End();
    }
}

Obviously, this code does not allow to display any “Thank you” message. Is there an “AfterRender” event or something similar of the Page where, I could move this download code and give a chance for the page to render the “thank you” message to the user? After all, I am truely thankful to them, so I do want to express that.

Answer 1

You could reference a download page from your thank you page using an IFrame

<iframe src="DownloadFile.aspx" style="display:none;" />

In this case, DownloadFile.aspx would have the code behind from your example.
