我是Silverlight的新手。打印時，我需要刪除DatePicker圖標。所以我編寫了這個代碼來在打印時刪除圖標。如果點擊打印對話框中的打印按鈕，它正常工作。但如果我關閉打印對話框日期選取器圖標不會出現。我必須在打印對話框關閉的情況下編寫代碼。我無法找到打印對話框的事件。如何處理Silverlight中的打印對話框關閉事件5
這是打印的代碼：

{
if (ele is FirstPageTC)
{
if ((ele as FirstPageTC).Content is StackPanel)

if ((ele as FirstPageTC).Content is Grid)
Download_Grid((ele as FirstPageTC).Content as Grid);

{
