新建一个网站

将控件添加到工具箱中，在工具箱中点击鼠标右键，点选选择项菜单，然后在弹出的对话框中点击浏览按钮，找到编译后的 SqlPaging.dll 最后点击确定按钮即可。

新建一个 Default2.aspx 页面然后在页面中添加控件 GridView Datalist 各一个添加两个 SqlPaging 控件添加一个按钮控件如下图

然后设置 SqlPaging 控件的两个重要的属性如下图

下面是控件的测试页面 default2.aspx 文件的html源码

<%... Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>

<%... Register Assembly="SqlPaging" Namespace="DRMSystem.DataLayer" TagPrefix="drmsp" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<tr>

GridView Sample<br />

<br />

<asp:GridView ID="GridView1" runat="server" Width="100%">

</asp:GridView>

<br />

<drmsp:SqlPaging ID="SqlPaging1" runat="server" StoredProcedureName="sys_QuickSortPaging" ControlToPaginate="GridView1" />

</td>

</tr>

<tr>

</td>

</tr>

<tr>

DataList Sample<br />

<br />

<asp:DataList ID="DataList1" runat="server" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal" HorizontalAlign="Justify" RepeatLayout="Flow" Width="100%">

<%...#DataBinder.Eval(Container.DataItem, "EmployeesID")%>

<%...#DataBinder.Eval(Container.DataItem, "LastName")%>

<%...#DataBinder.Eval(Container.DataItem, "FirstName")%>

<%...#DataBinder.Eval(Container.DataItem, "BirthDate")%>

<%...#DataBinder.Eval(Container.DataItem, "Address")%>

<%...#DataBinder.Eval(Container.DataItem, "City")%>

<%...#DataBinder.Eval(Container.DataItem, "HomePhone")%>

<%...#DataBinder.Eval(Container.DataItem, "Extension")%>

</ItemTemplate>

</asp:DataList><br />

<drmsp:SqlPaging ID="SqlPaging2" runat="server" ControlToPaginate="DataList1" StoredProcedureName="sys_QuickSortPaging" />

<asp:Button ID="Button1" runat="server" Text="生成1百万条测试数据" />

更具硬件大约需要 5-20 分钟</td>

</tr>
