AjaxToolKit学习笔记 之 Accordion

1.功能描述

功能类似于TAB选项卡，可以将一组功能相似任务相同的内容放在选项卡内，然后通过选项卡的标题查看各组内容．　就像我们VS开发工具中的工具栏．

2.属性说明

SelectedIndex：已显示的AccordionPane控件的索引号．

HeaderCssClass：作用于标题的CSS样式．可以指定Accordion控件的HeraderCssClass属性，以此作为所有AccordionPane控件的默认属性值．或者直接指定定单独的AccordionPane控件的HeraderCssClass属性．

ContentCssClass：用于显示内容的CSS样式．使用方法类似于HeaderCssClass．

FadeTransitions：为true时是渐变效果（在伸缩时颜色变淡，伸缩完成后恢复正常）；为false时是标准变换．

TransitionDuration：在选择一标题后伸展和收缩过渡动画持续的时间，单位为毫秒．

FramesPerSecond：用于伸展和收缩过渡动画每秒所需要的帧数．

AutoSize：用于限制Accordion控件展开的高度．None：没有限制；Limit：不能超过控件的最开始设置高度．如果显示内容太多则会出现滚动条．Fill：始终精确保持和高度设置一样的尺寸．

Panes：AccordionPane控件集合．

HeaderTemplate：标题模板，其中包含的标记用于进行数据绑定来显示面板标题．

ContentTemplate：内容模板，其中包含的标记用于进行数据绑定来显示面板内容．

DataSource：指定数据源，必须要调用DataBind（）方法进行数据绑定．

DataSourceID：用数据源的ID来指定一个数据源．

DataMember：当使用DataSourceID来指定数据源时用于绑定的成员．
