I need to disable events for a control in order to avoid recursion. What is the easiest way to dynamically disable events for a control (or other class with events) in VB.NET?

I'm familiar with the AddHandler and RemoveHandler implementation, but I was hoping for something a little less cumbersome. Something like the Application.EnableEvents method of VBA.

Any suggestions?

I would suggest setting a boolean variable to false before your operation and resetting it after. Test this variable in the the event handler and only do something if it is true.

I also use the suggestion from Dhaest. For example, I have a IsLoading property/variable and in some methods I have this kind of code

private sub X()
   If IsLoading then Return
   IsLoading = True
   Try
       ...
   Finally
      IsLoading = False
   End Try
end sub

I guess thats a effortless, but effective way of doing it :) I must admit however that I had hoped for something like Form.DisableEvents = True to exist in .NET.
