AJAX控件AutoCompleteExtender 如何将默认选项定位到第一条记录

这个控件默认情况下，是没有默认项，需要选择才可以。
如果修改他的元代码 应该修改什么呢？

    _onGotFocus: function(ev) {
        /// <summary>
        /// Handler for textbox focus event.
        /// </summary>
        /// <param name="ev" type="Sys.UI.DomEvent" DomElement="false" mayBeNull="false" />
        /// <returns />      
        this._textBoxHasFocus = true;
        if (this._flyoutHasFocus) {
            // hide the flyout now that the focus is back on the textbox
            this._hideCompletionList(); 
        }
        if ((this._minimumPrefixLength == 0) && (!this.get_element().value)) {
            this._timer.set_enabled(true);
            // only start the timer if the minimumprefixlength is 0
            // since we would like to retrieve results even if
            // the user has not entered any text and the textbox is empty.
        }
    },
