In the last few days Ive been searching books and websites to get back to "object oriented programming" I remember in my head from back time in college java and C++ courses about classes, event handling, delegates, inheritance .. etc but cant seem to get what I have in mind done in current C# development work requirements as custom electronic request forms automation, built with custom .net controls in SharePoint environment to be reused among them all when needed.

in this post Ill be showing you how to raise an event from within usercontrols native controls events and handle it with a custom code in webpage code file hosting the usercontrol.

watching Kudvenkats YouTube videos below helped a lot to understand the event handling technique by following the 5 steps to raise an event from the usercontrol

1. Step 1: Create XxEventArgs class that will contain the event data.
2. Step 2: Create XxChangedEventHandler delegate that raises this event. 
3. Step 3: Create XxChanged event that is a variable of type delegate.
4. Step 4: Create a protected virtual method to raise the event that enables the derived classes to do some additional work before the event can be raised. 
5. Step 5: Finally raise the event, whenever the usercontrols controls is changed.

Lets say, we want to raise TimeChanged event every time the usercontrol ( from the previous post ) controls values changes. i.e, when hours TextBoxs Text is changed, minutes TextBoxs Text is changed, or time DropDownLists Index is Changed.
