    //fd.AddExtension=true;
    if(fd.CheckPathExists)
    {
  
    
     // Insert code to set properties and fields of the object.
     XmlSerializer mySerializer = new
      XmlSerializer(contextMenu1.SourceControl.GetType());
     // To write to a file, create a StreamWriter object.
     StreamWriter myWriter = new StreamWriter(fd.FileName);
     mySerializer.Serialize(myWriter,contextMenu1.SourceControl);
    }
   }
   catch(Exception ex)
   {
    MessageBox.Show("please repeat"+ex.ToString());
