Ajax Toolkit Calendar Extender bold current date, ASP.NET

I am using Ajax Toolkit Calendar Extender, and i want to bold the current date, when calendar pops up.

var a = "1";
var b = "";

function ShowToday(e) {
    if (a == "1") {
        a = $("td.ajax__calendar_active > div").attr('id');
        a = '#' + a;
        b = a;
        $(a).css('font-weight', 'bold');
    }
    else {
        $(b).css('font-weight', 'bold');
    }
}

function CurrentDateShowing(e) {
    if (!e.get_selectedDate() || !e.get_element().value) {
        e._selectedDate = (new Date()).getDateOnly();
    }
}

I am uisng "CurrentDateShowing" function on OnClientShowing event, and "ShowToday" on OnClientShown event.

Currently I am using this javascript, but this script has a problem when i am switching on another mont开发者_StackOverflow社区h, the cell which was the cell of current date is still bold. How can I overcome this problem. And another problem, when i have two Calendar Extenders on the page this does not work. Please Help.

Use CSS to style the "today" element:

.ajax__calendar_today { font-weight: bold; }

Full details of the CSS classes available are on the Samples Site

You can modify your css code to change the style.
.ajax__calendar_active : This is applied to an element in the DOM above a day, month or year and is used to apply CSS attributes that show the currently selected value.

.ajax__calendar_active
 {
      font-weight:bold;
 }
