}
/// <summary>

PagerModel代码：
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Web; namespace ClientModels
{

[Serializable]
public class PagerModel

#region 字段

/// </summary>
public int page { get; set; }
/// <summary>
/// 每页记录数
/// </summary>
public int rows { get; set; }
/// <summary>
/// 排序字段
/// </summary>
public string sort { get; set; }
/// <summary>
/// 排序的方式asc，desc
/// </summary>
public string order { get; set; }
/// <summary>
/// 记录
/// </summary>
public object result { get; set; }
/// <summary>
/// 记录数
/// </summary>
public int totalRows { get; set; }
#endregion #region 构造函数
public PagerModel()
{ }
/// <summary>
///
/// </summary>
/// <param name="page">当前页数</param>
/// <param name="rows">每页记录数</param>
public PagerModel(int page, int rows)
{
this.page = page;
this.rows = rows;
}
#endregion #region 扩展字段
/// <summary>
/// 总页数
/// </summary>
public int pageCount
{
get
{
if (rows != )
{
return (totalRows - ) / rows + ;
}
else
{
return ;
}
}
}
/// <summary>
/// 上一页
/// </summary>
public int prePage
{
get
{
if (page - > )
{
return page - ;
}
return ;
}
}
/// <summary>
/// 下一页
/// </summary>
public int nextPage
{
get
{
if (page + < pageCount)
{
return page + ;
}
return pageCount;
}
}
#endregion }
}
如何使用：
PagerModel pager = pagerControl.Pager;
List<BS_Meeting_ext> list;
if (cbxReviewTime.Checked)
{
list = m_MeetingDal.GetList(ref pager, cbxType.SelectedValue.ToString(), txtTerm.Text, txtNum.Text, dtpStart.Value.ToString("yyyy-MM-dd"), dtpEnd.Value.ToString("yyyy-MM-dd"));
}
else
{
list = m_MeetingDal.GetList(ref pager, cbxType.SelectedValue.ToString(), txtTerm.Text, txtNum.Text, null, null);
}
pagerControl.Pager = pager;
