Mas como é que preencheste as combo? Com um DataSet? Em código?

É que, em príncipio, tens de capturar o evento ComboBoxIndexChanged para actualizar a 2ª combobox

boas,

os comboboxs estam ligados ao dataset.

DataSource  TbEstadoBindingSource

Display Member Estado

Display Value CodEstado

selected value bindingSource1-CodEstado

DataSource  TbEstadoBindingSource

Display Member cidade

Display Value CodEstado

selected value bindingSource1-Nomecidade

possivelmente será um selecte na query dentro do evento ComboBoxIndexChanged.

agradeço um link ou ajuda .

pode ser em c# ou VB mas prefiro em c#
