code behind

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Response.Clear();
    Response.ContentType = "application/octet-stream/mp4";
    Response.AppendHeader("Content-Disposition", "filename=" + e.CommandArgument);
    Response.TransmitFile(Server.MapPath("~/video/") + e.CommandArgument);
    Response.End();
