Hi All,
I want to create custom control by using Web.UI.WebControls.Calendar,
in which I want to set few days with different color. I had created two
property to set the color and storing in viewstate. I had created 4
methods to Add/Remove my special dates in viewstate.
Up to here all seems perfect, but how do I used it in prerender event
for my new calendar control.
Scenario:
I want to creae a web applicaiton which for Even Organizer.
I want to create my own custom calendar control/ User control which
show the dates in different color. There are list of dates on which the
event is organized, and there are few dates which are expiered. I want
to display this dates in two different color. I can easily implement it
in OnDayRender(object sender, DayRenderEventArgs e) event of system
calendar control. But i want to use same functionality on multiple web
pages, and for that i want to create Custom Control/User Control.
My quesion is where should i put my code to change the color of dates.
Below is my stuff. Your ideas also most welcomed.
Thanks & Regards,
Rushikesh
