如何將gridview綁定到另一個網格視圖？

Question

我在我的項目中使用2 gridview，我將員工綁定在一個網格上，我想在第二個網格上顯示每個員工的訂單。我被卡在過濾其他員工，當我點擊顯示訂單按鈕時​​，它顯示我所有的訂單，我如何指向正確的索引（員工選擇）？ 。

我的代碼：

private void Form3_Load(object sender, EventArgs e) 
{ 
     using (NorthWindDataContext db = new NorthWindDataContext()) 
     { 

      var query = 
       from d in db.Employees 
       select new 
     { 
      d.FirstName 
     }; 
      dataGridView1.DataSource = query; 
     } 

} 

private void displayOrdersToolStripMenuItem_Click(object sender, EventArgs e) 
{ 
     using (NorthWindDataContext db = new NorthWindDataContext()) 
     { 

      var query = 
       from o in db.Orders 
       select new 
       { 
        o.ShipName <----problem here :(
       }; 
      dataGridView2.DataSource = query; 

     } 
} 

請幫

感謝

使用GridView.SelectedValue屬性。

你需要寫類似於：

private void displayOrdersToolStripMenuItem_Click(object sender, EventArgs e) 
{ 
    using (NorthWindDataContext db = new NorthWindDataContext()) 
    { 

     var query = 
      from o in db.Orders. 
       Where(item => item.ID == dataGridView1.SelectedValue) 
      select new 
      { 
       o.ShipName <----problem here :(
      }; 
     dataGridView2.DataSource = query; 

    } 
}
