I usually use custom class (or line) for functional objects. Don't remember ever using Control class.

With the idea of container, do you mean you can have container based class for grid column's object? But if this is the case, perhaps, we can subclass Column class and add incremental search to the column class instead? I haven't thought of this.

My particular problem is already resolved, but I'd like to learn all possible approaches here.

Thanks again.
