把它定义在用户控件中的。在。ASCX中写的。

在CSDN上看了很多的DATAGRID分页问题，当然DATAGRID有自己的分页项，功能是很有限的，我也在CSDN上看了很多自己分页的代码，发现都是用C#写的，我写了一个用ASP。NET中VB语言写的。以下代码供大家参考。

HTML代码：

<%@ Control Language="vb" AutoEventWireup="false" Codebehind="DataGridPage.ascx.vb" Inherits="datagridfenye.DataGridPage" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>

runat="server" Visible="True">

BorderWidth="1px" CausesValidation="False" BackColor="#E0E0E0" Font-Size="XX-Small">

BorderWidth="1px" CausesValidation="False" BackColor="#E0E0E0" Font-Size="XX-Small">

BorderWidth="1px" CausesValidation="False" BackColor="#E0E0E0" Font-Size="XX-Small">

BorderWidth="1px" CausesValidation="False" BackColor="#E0E0E0" Font-Size="XX-Small">

runat="server">
