Hi,

We have a grid that we put an UltraCombo control in the EditorComponent property of one of the column.

This works great but when we have a lot of data (e.g. 30 000 rows), it take a couple of seconds to create the datasource.

The same UltraCombo control with the same datasource directly on a form; not in the EditorComponent of a grid is approximatly 500% faster. (1.5 seconds instead of 6 seconds)

Does anybody know why the datasource is slower to initialize in the grid?

I think the reason is that the EditorComponent create a clone of the AutoComplete and that clone process many things that when put in form directlly don't process.

(I know that you will tell me that is a huge quantity of data but my customer want it like that)
