"Visible" is true, but it not working

This is my code:

string result = BackUp.BackupDatabase(folder, fileName);
if (result == "Complete")
{
    BackupSuccessfullyLbl.Text = "BackUp created successfully.";
    BackupSuccessfullyPnl.Visible = true;
    if (BackUpPlaceRBL.SelectedIndex == 1)
    {
        var file = new System.IO.FileInfo(folder + fileName);
        Response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);
        Response.AppendHeader("Content-Length", file.Length.ToString());
        Response.TransmitFile(file.FullName);
    }
}

By default "Visible" of "BackupSuccessfullyPnl" is false.

I have created a back-up from my db, then I have showed the successfull message.

I want to download the created file, if BackUpPlaceRBL.SelectedIndex == 1.

When BackUpPlaceRBL.SelectedIndex != 1, the "BackupSuccessfullyPnl" is shown perfectly. But when file is downloaded, panel is not visible. what is wrong?

TransmitFile take full control of the response.

so although you set True to visibility of the control , the output response is actually a file which is downloaded. that's why you dont see the changes.

So what can I do?

great.

you create an iframe which hosts a page which has this code of downloading a file(only).

and on your main screen(page) you can set the visible=true.
