    [CLOSED] V2.0 ComboBox Editable

    Hi, i have a problem with a combox editable, i have 2 Store, the first content the Continents and the second the Nations, load the store and in a grid panel show the Nations with GroupingSummary from Continets, in the formPanel when click on the gridpanel load the nation e the combo show the continent of the nation correctly.
    Now execute this actions:

    1) Select "Italia" from the grid panel
    2)Click in the combobox and type "Eu", it's show "Europa"
    3)Select "Cina" from the GridPanel, the combobox not show "Asia" but show "Select a state"

    He seems to have applied a filter on the combobox for "Europa"

    Now execute this actions:
    1)Open the dropdown combobox and close.
    2)Select from GridPanel "Italia" and reselect "Cina"

    it's work the combobox show "ASIA"..

    In the 1.2 it's work fine, the problem is only the type in the combobox, se not type but select the line with the mouse, it works fine.

    Here it the code for the sample:

    Hi @Aurelio,

    Yes, there is the default functionality in Ext.NET v2 to filter ComboBox items on user input.

    To fix please clear filter before applying a value:
