分配的GridView值文本框中

Question

我要問有關C＃中的問題，Asp.net ...我在3文本框爲EMPID，姓名和地址

如果我點擊「編輯按鈕」與在文本框中手動輸入empid。我想分配其他兩個值名稱&地址到他們的文本框。然後我使用更新按鈕更新

任何人都可以教我與代碼？

//Asp.net 

<form id="form1" runat="server"> 
<div> 
    <asp:Label ID="Label1" runat="server" Text="Empid" Width="50px"></asp:Label> 
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
    <br /> 
    <asp:Label ID="Label2" runat="server" Text="Name" Width="50px"></asp:Label> 
    <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> 
    <br /> 
    <asp:Label ID="Label3" runat="server" Text="Address" Width="50px"></asp:Label> 
    <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox> 
    <br /> 
    <br /> 
    <br /> 
    <br /> 
    <asp:GridView ID="GridView1" runat="server"> 
    </asp:GridView> 
    <br /> 

</div> 
    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="update " /> 
    <asp:Button ID="Button2" runat="server" Text="Edit" Width="61px" /> 
</form> 



//Cs for update button 


    SqlConnection conn = new SqlConnection("Data Source=s\\SQLEXPRESS;Initial catalog = sample;Integrated security=True"); 
    SqlCommand cmd = new SqlCommand("UPDATE empdetails SET Name='" + TextBox2.Text + "',Address='" + TextBox3.Text + "' WHERE Empid ='" + TextBox1.Text + "'", conn); 
    conn.Open(); 
    cmd.ExecuteNonQuery(); 
    cmd.CommandText = "SELECT * FROM Empdetails"; 
    GridView.DataSource = cmd.ExecuteReader(); 
    GridView.DataBind(); 
    TextBox1.Text = ""; 
    TextBox2.Text = ""; 
    TextBox3.Text = ""; 
    conn.Close(); 

我這樣的代碼，如果我編輯按鈕，用輸入EMPID，我想其他值命名&地址會分配到文本框中

步驟：

1. 在GridView中獲取員工詳細信息。

   Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load 
       GetEmpDetails() 
   End Sub 
   Private Sub GetEmpDetails() 
   SqlConnection conn = new SqlConnection("Data Source=s\\SQLEXPRESS;Initial catalog = sample;Integrated security=True"); 
   
   conn.Open(); 
   
   cmd.CommandText = "SELECT * FROM Empdetails"; 
   GridView.DataSource = cmd.ExecuteReader(); 
   GridView.DataBind(); 
   End Sub 
   

2. 將此屬性AutoGenerateSelectButton="True"添加到設計頁面的gridview中。

   <asp:GridView ID="GridView1" runat="server" 
         AutoGenerateColumns="False" 
         AutoGenerateSelectButton="True" 
         CellPadding="4" > 
   </asp:GridView> 
   

3. 對電網的的SelectedIndexChanged得到的rowIndex，這樣我們將獲得選擇的行的行值。

   Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridView1.SelectedIndexChanged 
       LoadValues(GridView1.SelectedRow.RowIndex) 
   End Sub 
   

4. 然後將網格值加載到相應的文本框中。

5. ，並更改你想，但不改變ID值（強烈推薦）

6. 然後點擊UpdateButton。在那裏調用更新查詢。
7. 重新加載網格值並將其綁定。這樣你就可以立即看到變化。

Happy Coding .. !! :)
