Here is your code dropdown in checkbox which give you a result in alert message.Hope this will work for you. String message = ; foreach ( ListItem sp in listSports.Sports) { if (item.Selected) { message += sp .Text +   + sp .Value + \n ; } } ClientScript.RegisterClientScriptBlock( this .GetType() alert  alert(' + message + ');  true ); }
