C# 如何在datagrid中添加新行（datatable中的源）

如何在单击我的按钮时添加新行？谢谢：）

示例代码：

private void button1_Click(object sender, RoutedEventArgs e)
{
  DataTable dt = new DataTable();
  dt.Columns.Add("id");
  dt.Columns.Add("Name");

  dt.Rows.Add("1","John");
  dataGrid1.ItemsSource = dt.DefaultView;
}

DataTable dt = new DataTable ("Table_AX"); 

// Method 1 
dt.Columns.Add ("column0", System.Type.GetType ("System.String")); 
// Method 2 
DataColumn dc = new DataColumn("column1",System.Type.GetType("System.Boolean")); 
dt.Columns.Add (dc);

动态创建表、添加克隆、添加行

1-创建新的数据表

private void button1_Click(object sender, RoutedEventArgs e)
{
  DataTable dt = new DataTable();
  dt.Columns.Add("id");
  dt.Columns.Add("Name");

  dt.Rows.Add("1","John");
  dataGrid1.ItemsSource = dt.DefaultView;
}

DataTable dt = new DataTable ("Table_AX"); 

// Method 1 
dt.Columns.Add ("column0", System.Type.GetType ("System.String")); 
// Method 2 
DataColumn dc = new DataColumn("column1",System.Type.GetType("System.Boolean")); 
dt.Columns.Add (dc);

2-将列添加到数据表中

private void button1_Click(object sender, RoutedEventArgs e)
{
  DataTable dt = new DataTable();
  dt.Columns.Add("id");
  dt.Columns.Add("Name");

  dt.Rows.Add("1","John");
  dataGrid1.ItemsSource = dt.DefaultView;
}

DataTable dt = new DataTable ("Table_AX"); 

// Method 1 
dt.Columns.Add ("column0", System.Type.GetType ("System.String")); 
// Method 2 
DataColumn dc = new DataColumn("column1",System.Type.GetType("System.Boolean")); 
dt.Columns.Add (dc);

3-向数据表添加行

private void button1_Click(object sender, RoutedEventArgs e)
{
  DataTable dt = new DataTable();
  dt.Columns.Add("id");
  dt.Columns.Add("Name");

  dt.Rows.Add("1","John");
  dataGrid1.ItemsSource = dt.DefaultView;
}

DataTable dt = new DataTable ("Table_AX"); 

// Method 1 
dt.Columns.Add ("column0", System.Type.GetType ("System.String")); 
// Method 2 
DataColumn dc = new DataColumn("column1",System.Type.GetType("System.Boolean")); 
dt.Columns.Add (dc);

  DataRow dr=dt.NewROw();
  dr[0]="a";
  dr[1]="abc";
  dt.Rows.Add(dr);
  dataGrid1.ItemsSource = dt.DefaultView;
}
