Constant Line Collection Editor

[User (Legacy)]

I am trying to use the System.ComponentModel.Design.CollectionEditor at 

runtime to allow the end user to configure ConstantLines and 

ConditionalAttributes. This works fine except for the fact that the Add / 

Remove buttons are grayed out. I am assuming that this is because these 

collections do not implement IList. Even though they have implementations 

for Add and AddRange etc.? If this is the case then how does the 

CollectionEditor work at design time?

Anyone have any ideas on this. I want to expose all the customizable 

attributes of these classes to the user in the UI without having to recreate 

the collection editor manually.

Thanks,

You need to implement a class that derives from CollectionEditor, 

overriding:

protected override object SetItems(object editValue,object[] value)

and

protected override Type CreateCollectionItemType()
