Lets say we have a delegate
public delegate void MyEventHandler(string x);
and an event handler
public event MyEventHandler Something;
we add multiple events..
for(int x = 0; x <10; x++)
{
this.Something += HandleSomething;
}
My question is .. how would one remove all methods from the eventhandler presuming one doesn't know its been added 10 (or more or less) times?

Go to the objects tab, view the Document object (don't click on edit) and scroll down to Event Handlers. Select the one to delete and press delete.
To remove all event listeners from an element: Use the cloneNode() method to clone the element. Replace the original element with the clone. The cloneNode() method copies the node's attributes and their values, but doesn't copy the event listeners.
removeEventListener() The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget. addEventListener() from the target.
Simply set the event to null:
this.Something = null;
It will unregister all event handlers.
