SilverLight 4，DataGrid，DataGridColumnHeader，MouseLeftButtonDown事件

Question

DataGridColumnHeader事件MouseLeftButtonDown。我怎樣才能使用這個事件？

我如何加入DataGridColumnHeader與DataGridColumn？我見過

for Example: 
... 
    DataGridTextColumn TC; 
    TC = new DataGridTextColumn(); 
    TC.Header = "ID"; 
    TC.Binding = new Binding(); 
    TC.Binding.Converter = new MyCustomConverter(); 
    TC.Binding.ConverterParameter = 0; 

    // I need something like this: 
    TC.MouseLeftButtonDown += new event .... 
    // i need - when click on column header, my custom function will executed. 

    dataGrid.Columns.Add(TC);

最壞的代碼;）SRY ü應該使用的方法（回調）/λ確保滿足事件委託簽名來處理該事件

回調方法：

TC.MouseLeftButtonDown += MouseLeftButtonDownHandler; 
//define callback 
private void MouseLeftButtonDownHandler(object sender, MouseButtonEventArgs mouseButtonEventArgs) 
{ 
    //write ur logic here... 
} 

Lambda方法

TC.MouseLeftButtonDown += (sender, args) => {//write ur logic here} 
//where "sender" means the object raises the event(i.e. "TC"), args - object contains some helpfull information about the happened event(like "ClickCount", etc.).
