一、委托
WPF 子窗口对父窗口进行操作
这个需要借助委托事件来完成
首先需要在子窗口添加一个委托事件,在父窗体的按钮事件中注册此委托事件,然后处理即可.
子窗体:
public delegate void AddButtonDelegate();
public event AddButtonDelegate addButtonEvent;
private void button1_Click(object sender, RoutedEventArgs e)
{
//抛出事件
addButtonEvent();
}
父窗体:
private void button3_Click(object sender, RoutedEventArgs e)
{
Window2 win = new Window2();
win.addButtonEvent += new AddButtonDelegate(AddButton);
}
private void AddButton()
{
Button btn1 = new Button();
//添加进去按钮
}
