Hi everybody,

Is There an article or example that explain how to implement ensurerange
in Bold?
We found the IBoldListCore but We don´t know how to use it.

Thanks for help.

It is already implemented at TBoldList and TBoldObjectList. Do you want to
implement it at some other classes?

What I need is to show the data on a grid.
My grid has more or less 20 lines. My class has more or less 50.000
instances.

When I put Class.allinstances in a ListHandle it loads all the instances
on memory and my application go from 40 Mgb to 100 mgb on memory (each
class I read it improves memory)
I want it loading only the 20 lines shown on the grid and refreash it
all times I role the grid up or down.

Other problem. I have a class with more than 90000 instances.

When I do following :
class.allinstances->select(atribute = 0) : it runs ok
class.allinstances->select(atribute <> 0) : it runs ok
class.allinstances : it gives me an access violation.
I´m using the RadStudio boldgridpro.

Any sugestion?

Thanks for help
