Hi..

i would like to add a calendar in my windows application form.
i have added some dates as special in a table.
i would like to display that dates as bold or in different color when that particular month is selected.
can any one help me to customize the calendar??

should i need to create a user control???
If yes, which property i have to set to display the dates as bold??
