Question

winform问题：在子窗体中为父窗体添加子窗体？

Answer 1

有很多方法，推荐委托法 :

form1.cs

private void button1_Click(object sender, EventArgs e)
{
Form2 form = new Form2();
form.Todo += new EventHandler<EventArgs>(form_Todo);
form.ShowDialog();
}

void form_Todo(object sender, EventArgs e)
{
//做你想做的事。如:

TextBox test = new TextBox() { Size = new System.Drawing.Size(100, 21), Location = new System.Drawing.Point(5, 5) };
this.Controls.Add(test);
}

form2.cs
public partial class Form2 : Form
{
public event EventHandler<EventArgs> Todo;

public Form2()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
if (Todo != null)
Todo.Invoke(this, new EventArgs());
}
}

直接实例化窗体后把属性父窗体设置为该子窗体的父窗体即可
