    Hello,
    I need to load a large number of items inside3 different combobox (consider a class of type ID,Name,Country), for now the items are 9000 but will grow up shortly, I need to have them in a dropdown and enabling text-search on them... I got slow loading problem when binding more then 3000 items.... I supposed it should have a similar behavior like the gridview...

    can anyone tell me if it's possible to have an async load?

    I bind them as :

      cbClient.ItemsSource = m_listaClienti.Take(5000);

    Thanks in advance

    Paolo
