'AddHandler' and 'RemoveHandler' methods must have exactly one parameter
A custom event declaration must have AddHandler or RemoveHandler declarations, each of which takes a single parameter of the delegate type specified by the custom event's As clause.
Error ID: BC31133
To correct this error
- Remove the extra parameters from the parameter list, and change the parameter type to be the same as the delegate type specified by the custom event's As clause.
Example
This example shows a custom event with the correct parameter types for the AddHandler and RemoveHandler declarations.

AddHandler(ByVal value As System.EventHandler)
' Code for adding an event handler goes here.
End AddHandler
RemoveHandler(ByVal value As System.EventHandler)
' Code for removing an event handler goes here.
End RemoveHandler
RaiseEvent(ByVal sender As Object, ByVal e As EventArgs)
' Code for raising an event goes here.
End RaiseEvent
End Event
