GridView自带分页功能,但是模板单一,试用较少数据。

AllowPaging="true"

PageSize="10"

启用分页设置。默认每页数量为10

添加分页触发事件:
OnPageIndexChanging="GridView1_PageIndexChanging"

<PagerTemplate>
当前第:
<%--((GridView)Container.NamingContainer)就是为了得到当前的控件--%>
<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
页/共:
<%-- //得到分页页面的总数--%>
<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>

<%--//如果该分页是首分页,那么该连接就不会显示了.同时对应了自带识别的命令参数CommandArgument--%>
<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First"
     CommandName="Page" Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一页</asp:LinkButton>
<%-- //如果该分页是尾页,那么该连接就不会显示了--%>
<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾页</asp:LinkButton>
转到第
<asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' BorderStyle="None" />页
<%--//这里将CommandArgument即使点击该按钮e.newIndex 值为3--%>
<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-3" CommandName="Page" Text="GO"/> </PagerTemplate>

下面是添加分页触发事件(C#后台代码):
GridView1_PageIndexChanging

protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
// 得到该控件
GridView theGrid = sender as GridView;
int newPageIndex = ;
if (e.NewPageIndex == -)//点击了Go按钮
{
TextBox txtNewPageIndex = null; //GridView较DataGrid提供了更多的API,获取分页块可以使用BottomPagerRow 或者TopPagerRow,当然还增加了HeaderRow和FooterRow
GridViewRow pagerRow = theGrid.BottomPagerRow; if (pagerRow != null)
{
//得到text控件
txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
}
if (txtNewPageIndex != null)
{
//得到索引
newPageIndex = int.Parse(txtNewPageIndex.Text) - ;
}
}
else //点击了其他的按钮
{
newPageIndex = e.NewPageIndex;
}
//防止新索引溢出
newPageIndex = newPageIndex < ? : newPageIndex;
newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - : newPageIndex; //得到新的值
theGrid.PageIndex = newPageIndex; //重新绑定
bind();
}

最终分页样式:
