Aspx代码

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" 
Inherits="_Default" %>

<body>
    <form id="form1" runat="server">
    <div>

    </div>
    <asp:Button ID="Button1" runat="server" onclick="Button1_Click1" 
        Text="Button" />
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
        ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName 
%>" 
        SelectCommand="SELECT * FROM [Machine]"></asp:SqlDataSource>
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
    </asp:GridView>
    </form>
</body>
</html>

最初，Grid视图的DataSourceID未分配给SQLDataSource。我希望只在同一页面上按钮上显示表格。

参考 - execute sqldatasource with button

Gridview没有在ButtonClick上与SQLDataSource连接（不显示数据）
