I have a placeholder control where i have added the files from my folder. I have also binded a check box with each file How i can download the files if checkbox is clicked.

string strDir = Request.QueryString["d"] == null ? FileBrowerProperty.IntialPath : Request.QueryString["d"];

//read the directory
DirectoryInfo DirInfo = new DirectoryInfo(strDir);
//read the subdirectories inside the parent directory
DirectoryInfo[] subDirs = DirInfo.GetDirectories();
//read the files in the parent directory
FileInfo[] Files = DirInfo.GetFiles();

foreach (DirectoryInfo di in subDirs)
    ListItem listitem1 = new ListItem(di.FullName);
    // <a href='more.php' onclick='show_more_menu()'>More >>></a>
    //add the directory info to our table 
    LiteralControl lcFolders = new LiteralControl(@"<TR><TD style='WIDTH: 20px'><input type='checkbox' id='"
       + @di.FullName
       + "'>Directory</TD><TD style='WIDTH:350px'><a href='webform1.aspx?d=" 
       + @di.FullName + "'>" + di.Name + "</a></TD><TD style='WIDTH: 150px'>"
