Problem with TDBTree

Using mode with Code field and Parent field on a large dataset takes forever to load. (10M records+)

Even while there are only 20 records i n the root en next level.

Why aren't only the records loaded that are expanded? Am I mssing something here?

I guess I'll have to stay with my own TDBTree implementation which does load partial data.

Hi,

Partial load is not implemented in the TDBTree implementation. With TTree you can create a partial load, but if you want to use it together with a database, you indeed need to implement your own TCustomTree descendant.
