C#最簡單的關閉子窗體更新父窗體的實現方法

主窗體Form1關鍵代碼：

將子窗體最為對話框模式彈出，當窗體關閉或取消時更新主窗體
代碼如下：

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();
}
}

子窗體
代碼如下：

private void simpleButton1_Click(object sender, EventArgs e)
{
this.Close();
}

public DataTable CreateTable()
{
DataTable tableA1 = new DataTable();
tableA1.Columns.AddRange(new DataColumn[] { new DataColumn("名稱"), new DataColumn("規格"), new DataColumn("單號"), new DataColumn("數量") });
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[] { "指針", "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;
}
