Anjali we use DELEGATES when :

Creating custom events.
Asynchronous call back(when we need to call multiple function parallel).
Dynamic method calling.

Hi,

Delegate is similar to “C” language function pointer, where functions can be assigned like a variable and called at the run time based on dynamic conditions
Or
Delegate is the type that defines a method signature. To invoke a delegate object, one or more methods are required with the EXACT same signature. The delegate object will basically hold a reference of a function. The function will then can be called via the delegate object.

Check the following Reference :
