UltraCombo with data binding - performance issue when bound to 20k records
posted

Hi,

On a form I have 4 UltraCombos (2 x product code, product name) bound to a 2 properties (product1 code, product2 code) on a entity. The combos' data source is made of 20k product records. The combos are bound to 2 bindingsources, one for product1, the other for product2.

The editing form load extremely slow when the two properties on the entity is bound using DataBindings to the combo's values.

What can I do to speed it up?

The form is created only once, when the app is started. The products list is bound to the BindingSources at the same time. The form is shown only when the user add a new entit, or modifies an existing one.
