自定义分页/按钮

  使用GridView绑定了数据之后，设置allowpage=true之后，自动套用样式。下面的翻页按钮只有1 2 3 4 5 6等数字用于翻页，

如果想自己定义按钮，可用以下方法。

aspx文件

1. "DG" runat="server" AutoGenerateColumns="False">  //这里用的是datagrid 原理是一样的
3. "USERCODE" HeaderText="登录帐户">
4. "USERNAME" HeaderText="用户姓名">
5. "所属部门" DataField="ORGNAME">
6. "用户角色" DataField="ROLENAME">
7. "使用状态" DataField="ISUSE">
8. "修改" Text="修改">
9. "删除" Text="删除">
12. "l_CurrentPage" runat="server" oreColor="Red">
13. "l_PageCount" runat="server">页
14. "First" runat="server" CommandArgument="first" OnClick="PagerButton_Click">首 页
15. "Prev" runat="server" CommandArgument="prev" OnClick="PagerButton_Click">上一页
16. "Next" runat="server" CommandArgument="next" OnClick="PagerButton_Click">下一页                      
17.  "Last" runat="server" CommandArgument="last" OnClick="PagerButton_Click">尾 页
