  What is the most efficient way to implement cascading combobox. Fox example if i have three comboboxes in a form where one selection of country in 1st combobox, second combobox should populate with States in the country selected in Combobox 1 and when we select a State in 2nd combobox then 3rd combox should populate with cities based on country and state selected in 1st and 2nd combobox.

  Hi Leo,

  We have created a sample project using C1ComboBox to implement the cascading ComboBox as per your comments, please have a look into the sample and let us know if you found this useful or not.
