Hello sphinx,

Please feel free to contact me if you have any additional questions regarding this matter.

Hello Daryl007,

Thank you for your response and sharing your solution. In the old controls, successfully setting the even handlers from the code behind is not done as in the AIKIDO controls via delegates and that is one possible reason for the handlers not firing previously. Setting the event handlers from the code-behind is the best approach in this case.

I am trying this solution and trying to access the renderDay event from the calendar control.

Using custom days type routine, when they drop down the calendar, I need to have some days have a color change.

Here is the client JS that is rendered...

Do you see any issue as to why it isn't working?

EDIT... Oddly enough this wouldn't work with the events assigned in the server side code, when I assigned the events in the aspx code it worked fine

//
var customDays = [
[2014,12,31,'Red','This day is closed for New Year~s Day.']
, [2014,12,24,'Red','This day is closed for Christmas.']
, [2014,11,26,'Red','This day is closed for Day After Thanksgiving.']
, [2014,11,25,'Red','This day is closed for Thanksgiving.']
, [2014,9,6,'Red','This day is closed for Labor Day.']
, [2014,7,4,'Red','This day is closed for Independence Day.']
, [2014,5,31,'Red','This day is closed for Memorial Day.']
, [2014,1,19,'Red','This day is closed for Martin Luther King Jr. Day.']
, [2014,1,1,'Red','This day is closed for New Year~s Day.']
]
// ]]>

function renderDay(sender,evt) {
    try {
    var gday = evt.get_day();
      if(customDays == null) return;
      var d, back = "";
      var i = customDays.length;
      while(i-- > 0) {
          d = customDays[i];
          if(d == null || d.length
          if((d[0] == -1 || d[0] == gday.year) && (d[1]

          }
      }
