Silverlight Custom Grid с фиксированным заголовком и столбцом, необходимый рефакторинг

Question

Я пытаюсь создать пользовательскую сетку с фиксированным заголовком и столбцом в Silverlight. Я не знаю, построил ли SL встроенные функции для создания этого или нет, потому что я очень новичок в SL. Посмотрите следующий код. Я не думаю, что это правильный способ построить это. Если вы не возражаете, пожалуйста, отредактируйте мой код и сообщите мне правильный путь.

Спасибо большое за акцию кода, это было очень полезно для меня, чтобы построить свою сетку с замораживанием Колонны и Роу , Надеюсь, это поможет и другим. Вам нужно изменить позиции начала следующих элементов в соответствии с расположением, (scrollableGrid, HScrollBar, VScrollBar, colHeaderContainer, rowHeaderContainer)

 private Grid theGrid = new Grid();  
     private Canvas gridContainer = new Canvas();  
     private Canvas colHeader = new Canvas(); 
     private StackPanel colHeaderContainer = new StackPanel();  
     private Canvas rowHeader = new Canvas(); 
     private StackPanel rowHeaderContainer = new StackPanel();

     private Border firstRowfirstColCell = new Border();  
     private ScrollBar hScrollBar = new ScrollBar(); 
     private ScrollBar vScrollBar = new ScrollBar();

      for (int i = 0; i <= 10; i++) 
      {

       cdef.Width = new GridLength(100);
