摘要:GridView練習

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ProductID" DataSourceID="SqlDataSource1">

<asp:BoundField DataField="ProductID" HeaderText="產品ID" ReadOnly="True" SortExpression="ProductID" />

<asp:BoundField DataField="ProductName" HeaderText="產品名稱" SortExpression="ProductName" />

<asp:BoundField DataField="Quantity" HeaderText="品質" SortExpression="Quantity" />

<asp:BoundField DataField="Price" HeaderText="價錢" SortExpression="Price" />

</Columns>

</asp:GridView>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnection %>" SelectCommand="SELECT * FROM [Suppliers]"></asp:SqlDataSource>

GridView ID : 此ASP GridView的ID

DataKeyNames : 引入資料的主鑑值欄位名稱

DataSourceID : 引入的DataSource ID

PS: datasource宣告時資料庫語法會跟著

ConectionString 需在Webconfig中設置(使用精靈的話會自動幫你設置)

connectionString範例，請放在connectionStrings標籤裡

<add name="NorthwindConnection" connectionString="Data Source=CLRIS-PC\SQLEXPRESS;Initial Catalog=Northwind;User ID=sa;Password=sa"

providerName="System.Data.SqlClient" />

Columns標籤中

BoundField 為每一個資料列

DataField 填上資料庫欄位名稱

HeaderText 請填上想在網頁上顯示的欄位名稱

SortExpression="string" 可以使此欄位排序

↓某欄位加上編輯、刪除按鈕

<asp:TemplateField ItemStyle-Width="5%" HeaderText="動作">

<asp:Button ID="Button_review" Text="編輯" CommandName="review" runat="server" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"/>

<asp:Button ID="Button_Delete" Text="刪除" CommandName="Delete" runat="server" CommandArgument="<%# ((GridViewRow)

Container).RowIndex %>" OnClientClick="return confirm('確定刪除嗎？');" />

</ItemTemplate>

</asp:TemplateField>

後置程式碼對應

//GV裡面的編輯按鈕

if (e.CommandName == "review")

{

}

//GridView裡面的刪除按鈕

if (e.CommandName == "Delete")

{

}

流程

(1)Webcofig的ConnectString

(2)SqlDataSource 使用 (1)的字串

(3)GridView使用SqlDataSource的ID
