如何从一个存储过程填充多个 GridView 控件？

// 存储过程
CREATE PROCEDURE GetGridViewData
AS
BEGIN
    SELECT * FROM Table1
END

// ASP.NET 页面
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="GetGridViewData" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" DataKeyNames="ID">
   <Columns>
        <asp:BoundField DataField="ID" HeaderText="ID" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Age" HeaderText="Age" />
    </Columns>
</asp:GridView>

<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="GetGridViewData" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

<asp:GridView ID="GridView2" runat="server" DataSourceID="SqlDataSource2" DataKeyNames="ID">
   <Columns>
        <asp:BoundField DataField="ID" HeaderText="ID" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Age" HeaderText="Age" />
    </Columns>
</asp:GridView>

// 页面加载事件
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        SqlDataSource1.DataBind();
        SqlDataSource2.DataBind();
    }
}
