  • AJAX Control Toolkit PagingBulletedList

    PagingBulletedList is an ASP.NET AJAX extender that can be attached to an ASP.NET BulletedList control and provide client-side sorted paging. It is very flexible and lets you specify either the number of characters used in the heading indices or the maximum number of items to display per index. If the input is not sorted (either on the server or client), it will generated more header indices but still function appropriately.

    TargetControlID - The ID of the BulletedList to page.

    ClientSort - Whether or not the items should be sorted client-side.(Default is false)

    IndexSize - Number of characters in the index headings(ignored if MaxItemPerPage is set)(default is 1)

    MaxItemPerPage - Maximum number of items per page (ignores the IndexSize property)

    Separator - Separator text to be placed between indices.

    SelectIndexCssClass - Css Class for the selected index.

    UnselectIndexCssClass - CSS class for indices that aren't selected.

    79 </div>
    80 <input id="radioOption1" name="radioOption" type="radio" value="1" checked="checked"
    81 onclick="onChangeSelectOption()" />
    82 <label for="radioOption1">
    83 Index size 1</label>
    84 <input id="radioOption3" name="radioOption" type="radio" value="3" onclick="onChangeSelectOption()" />
    85 <label for="radioOption3">
    86 10 Items per page</label><br />
    87 <input id="radioOption2" name="radioOption" type="radio" value="2" onclick="onChangeSelectOption()" />
    88 <label for="radioOption2">
    89 Index size 2</label>
    90 <input id="radioOption4" name="radioOption" type="radio" value="4" onclick="onChangeSelectOption()" />
    91 <label for="radioOption4">
    92 20 Items per page</label>
    93 <br />
    94 <input type="checkbox" id="clientSort" checked="checked" onclick="onChangeClientSort()" /><br />
    95 <label for="clientSort">
    96 Sort</label>
    97 </div>

    该案例不是很明白:

    1.页面中不存在“PagingBulletedListBehavior1”这个ID的控件;

    2.JavaScript中的$find 和$get ,还有 bl.set_MaxItemPerPage(),bl.set_IndexSize(1)两个方法?

    {若是有人知道请告诉我哦!谢谢}
