I followed up the instructions on above mentioned topic, and found a solution (I think :), it is working for me AFAIK
). Here the code for the code manias out there, and I urge you to always provide the code since it makes things easier.
HyperLink datelink = new HyperLink();
datelink.Target = "#";//instead of having to loop for in JS :)
datelink.Text = e.Day.DayNumberText;
datelink.ID = "day_" + e.Day.Date.Month.ToString() + "_" + e.Day.Date.Day.ToString();
The above should go in the DayRender Event handler.
