gridView單行編輯功能的實現

HTML：

<asp:GridView ID="gvList" runat="server" AutoGenerateColumns="false" CssClass="grid" 
     DataKeyNames="ID" EmptyDataText="暫無記錄！" onrowediting="gvList_RowEditing" 
     onrowupdating="gvList_RowUpdating"  onrowcancelingedit="gvList_RowCancelingEdit" >
     <Columns>
          <asp:BoundField HeaderText="ID" ItemStyle-Width="20" DataField="ID"  Visible="false"  ItemStyle-HorizontalAlign="Center" ReadOnly="true"/>
          <asp:BoundField HeaderText="組織編號" DataField="DeptNo" ItemStyle-Width="20%"  ItemStyle-HorizontalAlign="center" ReadOnly="true"/>
          <asp:BoundField HeaderText="組織全稱" DataField="DeptName"   ItemStyle-Width="30%" ItemStyle-HorizontalAlign="Center" ReadOnly="true"/>
          <asp:TemplateField HeaderText="組織簡稱">
              <ItemTemplate>
                  <%#Eval("ShowName") %>
              </ItemTemplate>
              <ItemStyle HorizontalAlign="Center" Width="30%" />
                 <EditItemTemplate>
                    <asp:TextBox ID="tbShowName" Text='<%#Eval("ShowName") %>' runat="server" Width="100%"/>
                 </EditItemTemplate>
              </asp:TemplateField>
                  
           <asp:CommandField ShowEditButton="true" HeaderText="操作" EditText="編輯" UpdateText="更新" CancelText="取消"  ItemStyle-HorizontalAlign="Center"/>
    </Columns>
    <EditRowStyle BackColor="#999999" />
</asp:GridView>

ReadOnly="true"用於標示不需要編輯的列。
