C#教程之C#最简单的关闭子窗体更新父窗体的实现

主窗体Form1关键代码：

将子窗体最为对话框模式弹出，当窗体关闭或取消时更新主窗体

复制代码代码如下:

	
	private void simpleButton1_Click(object sender, EventArgs e)

	{

	Form2 f2 = new Form2();

	f2.Owner = this;

	DialogResult result=f2.ShowDialog();

	if (result == DialogResult.Cancel)

	{

	this.gridControl1.DataSource = f2.CreateTable();

	}

	}

子窗体

复制代码代码如下:

	
	private void simpleButton1_Click(object sender, EventArgs e)

	{

	this.Close();

	}

	public DataTable CreateTable()

	{

	DataTable tableA1 = new DataTable();

	tableA1.Columns.AddRange(new DataColumn[] { new DataColumn("名称"), new DataColumn("规格"), new DataColumn("单号"), new DataColumn("数量") });

	tableA1.Rows.Add(new object[] { "螺旋", "LS-X", "111", "2" });

	tableA1.Rows.Add(new object[] { "螺旋", "LS-X", "222", "1" });

	tableA1.Rows.Add(new object[] { "指针", "LX-3", "523", "2" });

	tableA1.Rows.Add(new object[] { "其他", "L-1", "666", "2" });

	tableA1.Rows.Add(new object[] { "其他", "L-1", "456", "1" });

	tableA1.Rows.Add(new object[] { "其他", "L-1", "990", "2" });

	return tableA1;

	}
