AJAX Toolkits -- ListSearch
在AJAX Toolkits中有个ListSearch扩展功能,其主要用于DropDownList和ListBox
当用户输入信息之后,其会对此进行定位查询。其属性如下:
- PromptText - 在对应控件的上方显示的初始信息,默认为'Type to search'. 当用户输入信息之后,该信息将会被用户实际输入的信息替代。注意,在布局该控件的时候,上方应留下部分距离
- PromptCssClass - 弹出信息的CssClass.
- PromptPosition - 弹出信息的位置,默认为TOP,这里还有Buttom选项。如果控件是DropDownList,应保证为TOP;如果是ListBox则两者都可以。
- Animations - Generic animations for the ListSearch extender. See the Using Animations walkthrough and Animation Reference for more details.
- OnShow - The OnShow animation will be played each time the extender's prompt is displayed. The prompt will be positioned correctly but hidden. The animation can use <HideAction Visible="true" /> to display the prompt along with any other visual effects.
- OnHide - The OnHide animation will be played each time the extender's prompt is hidden.
- 这个属性我没有使用,太复杂了
