请帮助.. 如何修改 ajax 日历扩展器中的日历扩展器显示以仅显示月份和年份，我的意思是日历视图而不是文本框文本格式，所以我只选择特定年份的月份名称。

所示的 OnClientShown 函数需要做的不仅仅是切换模式。这是我得到的解决方案，它只显示月份，您可以选择月份，并且只在文本框中显示月份和年份。
第1步
<asp:CalendarExtender ID="calendar1" ClientIDMode="Static" runat="server"
TargetControlID="txtDate" Format="yyyy-MM"
DefaultView="Months" OnClientShown="onCalendarShown"
OnClientHidden="onCalendarHidden" PopupButtonID="imgStart" />
请注意：ClientIDMode = Static、DefaultView = Months 以及附加的OnClientShown和OnClientHidden事件。
您还可以将 Format="yyyy-MM" 更改为您想要的任何格式，其中包含月份和年份。
第2步
创建这些 Javascript 函数。如果您没有加载 JQuery，请将 $find 更改为 document.getElementById
<script type="text/javascript">
function onCalendarHidden() {
var cal = $find("calendar1");
if (cal._monthsBody) {
for (var i = 0; i < cal._monthsBody.rows.length; i++) {
var row = cal._monthsBody.rows[i];
for (var j = 0; j < row.cells.length; j++) {
Sys.UI.DomEvent.removeHandler(row.cells[j].firstChild, "click", call);
}
}
}
}
function onCalendarShown() {
var cal = $find("calendar1");
cal._switchMode("months", true);
if (cal._monthsBody) {
for (var i = 0; i < cal._monthsBody.rows.length; i++) {
var row = cal._monthsBody.rows[i];
for (var j = 0; j < row.cells.length; j++) {
Sys.UI.DomEvent.addHandler(row.cells[j].firstChild, "click", call);
}
}
}
}
function call(eventElement) {
var target = eventElement.target;
switch (target.mode) {
case "month":
var cal = $find("calendar1");
cal._visibleDate = target.date;
cal.set_selectedDate(target.date);
//cal._switchMonth(target.date);
cal._blur.post(true);
cal.raiseDateSelectionChanged();
break;
}
}
</script>

在处理带有顽固脚本管理器的继承页面时，我的 javascript 函数未定义，我最终只是在 CalendarExtender 上将“DefaultView”的 html 属性设置为“Months”，如下所示：
<asp:CalendarExtender ID="dtPickerFrom" runat="server" CssClass="calendarClass" Enabled="true" Format="MMM-yy" PopupButtonID="imgcalendarFileDate" TargetControlID="TextBoxFileDate" DefaultView="Months">
</asp:CalendarExtender>
这是关联的属性及其选项：
结果：

CalendarExtender您可以简单地更改月份的显示模式。
步骤 1.OnClientShown向CalendarExtenderie添加一个事件。
<AjaxControlToolkit:CalendarExtender ID="calTitleLength" runat="server"
TargetControlID="txtMonth" OnClientShown="calendarShown">
</AjaxControlToolkit:CalendarExtender>
步骤 2.处理OnClientShown事件以切换日历模式，即。
function calendarShown(sender, e) {
sender._switchMode("months", true);
}
