ASP.Net 頁面中GirdView 源碼內容說明

在界面中添加了GirdView控件並增加數據源之后，在代碼中可以看見它的內容。

     < div >
         < asp:GridView ID = " GridView1 "  runat = " server "  DataSourceID = " EventDataSource "  BackColor = " White "  BorderColor = " White "  BorderStyle = " Ridge "  BorderWidth = " 2px "  CellPadding = " 3 "  CellSpacing = " 1 "  GridLines = " None " >
             < FooterStyle BackColor = " #C6C3C6 "  ForeColor = " Black "   />
             < RowStyle BackColor = " #DEDFDE "  ForeColor = " Black "   />
             < Columns >
                 < asp:BoundField DataField = " Id "  HeaderText = " Id "  ReadOnly = " True "  SortExpression = " Id "   />
                 < asp:BoundField DataField = " Title "  HeaderText = " Title "  SortExpression = " Title "   />
                 < asp:BoundField DataField = " Date "  HeaderText = " Date "  SortExpression = " Date "   />
                 < asp:BoundField DataField = " Location "  HeaderText = " Location "  SortExpression = " Location "   />
             </ Columns >
             < PagerStyle BackColor = " #C6C3C6 "  ForeColor = " Black "  HorizontalAlign = " Right "   />
             < SelectedRowStyle BackColor = " #9471DE "  Font - Bold = " True "  ForeColor = " White "   />
             < HeaderStyle BackColor = " #4A3C8C "  Font - Bold = " True "  ForeColor = " #E7E7FF "   />
         </ asp:GridView >

         < asp:SqlDataSource ID = " EventDataSource "  runat = " server "  ConnectionString = " <%$ ConnectionStrings:EventsConnectionString %> "
            SelectCommand = " SELECT [Id], [Title], [Date], [Location] FROM [Events] " ></ asp:SqlDataSource >  
     </ div >

說明：
    DataSourceID：定義了與數據源控件的關聯。(DataSourceID="EventDataSource")
    <Columns></Columns>：列出了用於顯示數據的所有綁定列
    HeaderText：此列的標題
    DataField：數據源中的字段名
    <asp:SqlDataSource></asp:SqlDataSource>：定義婁數據源
    SelectCommand：定義如何從數據庫中讀取數據
    ConnectionString：定義如何連接數據庫(ConnectionString="<%$ ConnectionStrings:EventsConnectionString %>")，連接字符串我們保存在配置文件web.config中，所以用<%$ 與配置文件中動態生成的類之間建立關聯。
