请问如何得到右键菜单是哪个对象引发的？
比如说我在textBox1,textBox2都调用了一个contextMenu1。
如何在menuItem1_Click中得到调用它的是textBox1还是textBox2。

Remarks:
You can use this event to initialize the MenuItem objects before they are displayed. For example, if you use a ContextMenu for three TextBox controls and you want to disable certain menu items in the ContextMenu depending on which TextBox is displaying the shortcut menu, you can create an event handler for this event. You could use the SourceControl property to determine which TextBox is about to display the ContextMenu and disable the appropriate MenuItem objects.
