<asp:DataGrid id="MyDataGrid" runat="server" CssClass="EmptyTable" AutoGenerateColumns="False" Width="99%" PageSize="15" AllowPaging="True">
<HeaderStyle CssClass="TableTop"></HeaderStyle>
<FooterStyle HorizontalAlign="Right"></FooterStyle>
<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="Id" DataNavigateUrlFormatString="Class.aspx?Id={0}" DataTextField="SchoolName" HeaderText="学校名称" DataTextFormatString="□{0}">
<HeaderStyle HorizontalAlign="Center"></HeaderStyle>
<ItemStyle CssClass="Left"></ItemStyle>
</asp:HyperLinkColumn>
<asp:BoundColumn DataField="ClassNumber" HeaderText="班级数量">
<HeaderStyle HorizontalAlign="Center" Width="20%"></HeaderStyle>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:BoundColumn>
<asp:HyperLinkColumn Text="进入" DataNavigateUrlField="Id" DataNavigateUrlFormatString="Class.aspx?Id={0}" HeaderText="进入">
<HeaderStyle HorizontalAlign="Center" Width="20%"></HeaderStyle>

private void MyDataGrid_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
MyDataGrid.CurrentPageIndex=e.NewPageIndex;
MyDataGrid.DataBind();
}

在DataGrid里增加PageIndexChange事件
然后加上面的代码

[blackcatiii]

你的code-behind代码里有没有这样写代码？
private void MyDataGrid_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
MyDataGrid.CurrentPageIndex = e.NewPageIndex;
BindGrid();//注意必须要重新绑定数据源
}
