DataGridColumnHeader 有事件 MouseLeftButtonDown。我该如何使用这个活动?

如何将 DataGridColumnHeader 与 DataGridColumn 一起加入?

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 );

我见过的最糟糕的代码;)你应该使用方法(回调)/ lambda 确保满足事件委托签名来处理事件

回调方法:

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.).
