Use reflection to remove and add events

[niteshs]

Hi all I want to be able to disable all events for controls on my form
at runtime based on a certain condition and then re-add these events
back.
I have been able to view events through the EventInfo[] class

EventInfo[] events =
comboBox1.GetType().GetEvent("SelectedIndexChanged");
and then looping through these.

Type mydel =
comboBox1.GetType().GetEvent("SelectedIndexChanged").EventHandlerType;

I need to be able to disable all SelectedIndexChanged events
I need to do something like events.RemoveEventHandler(combobox)

Cheers nitesh

You can't actually add and remove events from the classes. You can change
the list of properties, events, methods and so-on seen by the reflection
API's by using the ICustomTypeDescriptor interface. I have developed classes
that provide different property lists depending on the settings of their own
properties.
