AspNetPager6.0分页控件 增强版

 增加了可自定义每页的记录数,并修订了在ajax的情况下,js不能动态绑定页面记录数绑定的问题

部分代码如下:

 

       /**//// <include file='AspNetPagerDocs.xml' path='AspNetPagerDoc/Method[@name="RenderContents"]/*'/>

                writer.RenderEndTag();
                WriteCellAttributes(writer, false);
                writer.AddAttribute(HtmlTextWriterAttribute.Class, CssClass);
                writer.RenderBeginTag(HtmlTextWriterTag.Td);
            }

                for (int i = pageoffset + 1; i <= endpage; i++)
                ...{

                }
