aspnetpager分页控件_如何自动分页

一．如果你使用GET方式传递参数

如http://www.CSDN.com/indx?id=1&page=5

调用方式如下：

CSS样式:

.Dcssa{
padding:4px8px;border:1pxsolid#999999;color:#000000;margin-left:1px;}

.Scss{
padding:4px8px;}

控制器：

一：默认显示10个页数

ViewData[“Page”] = newAspNetMvcPage.MVCPage(10, 500, 3, “Dcss”, “Scss”,”page”,).RetureHtml();

二：自定义显示页数的显示个数(20个)
ViewData[“Page”] = new AspNetMvcPage.MVCPage(10, 500, 3,”Dcss”, “Scss”, “page”, 20).RetureHtml();

视图：

<%=ViewData[“Page”] %>

构造函数参数说明

/// <summary>

/// 默认链接模式(合适Get的URL传递参数模式)

/// </summary>

/// <param name=”url”>自定义链接地址</param>

/// <param name=”Number”>每页显示数</param>

/// <param name=”Count”>数据总行数</param>

/// <param name=”Page”>当前页数</param>

/// <param name=”DClassName”>外观DIV样式（可定义A链接样式）</param>

/// <param name=”SClassName”>当前选择页样式</param>

/// <param name=”PageName”>URL分页参数名</param>

public MVCPage(int Number, int Count, int Page, string DClassName,string SClassName,string PageName)

/// <summary>

/// 默认链接模式(自定义显示分页的个数，合适Get的URL传递参数模式)

/// </summary>

/// <param name=”url”>自定义链接地址</param>

/// <param name=”Number”>每页显示数</param>

/// <param name=”Count”>数据总行数</param>

/// <param name=”Page”>当前页数</param>

/// <param name=”DClassName”>外观DIV样式（可定义A链接样式）</param>

/// <param name=”SClassName”>当前选择页样式</param>

/// <param name=”PageName”>URL分页参数名</param>

/// <paramname=”ShowPageCount”>显示分页的个数</param>

public MVCPage(int Number, int Count, int Page, string DClassName,string SClassName, string PageName, int ShowPageCount)

二如果你使用自定义路径如

http://www.CSDN/index/1/5

调用方法如下：

CSS样式:

.Dcssa{
padding:4px8px;border:1pxsolid#999999;color:#000000;margin-left:1px;}

.Scss{
padding:4px8px;}

控制器：

一：默认显示10个页数

ViewData[“Page”] = newAspNetMvcPage.MVCPage(“http://www.csdn.com/index/@page/5”, 10, 500,3, “Dcss”, “Scss”).RetureHtml();

二：自定义显示页数的显示个数(20个)

ViewData[“Page”] = newAspNetMvcPage.MVCPage(“http://www.csdn.com/index/@page/5”, 10, 500,3, “Dcss”, “Scss”,20).RetureHtml();

视图：

<%=ViewData[“Page”] %>

构造函数参数说明

/// <summary>

/// 经典模式(自定义链接模式)

/// </summary>

/// <param name=”url”>自定义链接地址(页数用@page代替)</param>

/// <param name=”Number”>每页显示数</param>

/// <param name=”Count”>数据总行数</param>

/// <param name=”Page”>当前页数</param>

/// <param name=”DClassName”>外观DIV样式（可定义A链接样式）</param>

/// <param name=”SClassName”>当前选择页样式</param>

public MVCPage(string url,int Number,int Count,int Page,stringDClassName,string SClassName)

/// <summary>

/// 经典模式(自定义链接,显示分页的个数模式)

/// </summary>

/// <param name=”url”>自定义链接地址(页数用@page代替)</param>

/// <param name=”Number”>每页显示数</param>

/// <param name=”Count”>数据总行数</param>

/// <param name=”Page”>当前页数</param>

/// <param name=”DClassName”>外观DIV样式（可定义A链接样式）</param>

/// <param name=”SClassName”>当前选择页样式</param>

/// <param name=”ShowPageCount”>显示分页的个数</param>

public MVCPage(string url, int Number, int Count, int Page, stringDClassName, string SClassName, int ShowPageCount)
