Suspend CollectionChanged event in BaseCollection class

[Joe]

Hello,

I have a class that inherits from BaseCollection. I want to implement a Move
method so an item in the collection can be moved from one index postion to
another for example index = 5 to index = 2.

I don't want the CollectionChanged event to get called when I remove the
item and do an Insert.

Is there anyway to suspend the event in my class that inherits from
BaseCollection?

Thanks,
Joe

Can you clarify? The System.Windows.Forms.BaseCollection class doesn't
have a CollectionChanged event.

Sorry it turned out this was our BaseCollection.

Hi Joe,

Thank you for the clarify. Then, do you still need any help on this issue?

Basically, since you implement the event yourself, you may use some private
flag to control if this event should be fired. When you are implementing
the "Move" method, you may set this flag, so that the all the internal
operations will honor this flag and will not fire CollectionChanged event.

Thanks.

Best regards,
