    I design a function form as record finder in my Application. I want to use it instead of dropdownlist in a MultiColumnComboBox Column in a radgridview. Is it possible to do that?

    Hello, Cesar,   

    RadMultiColumnComboBoxElement, which is used as an editor in RadGridView's GridViewMultiComboBoxColumn, offers the CreatePopupForm method which can be overridden in a derivative. Thus, you can create a custom RadMultiColumnComboBoxElement and override its CreatePopupForm method where you can construct your own MultiColumnComboPopupForm. The custom editor can be applied in the EditorRequired event that RadGridView offers: 

    Another suitable control that can be hosted in a custom editor by using a RadHostItem is RadPopupEditor. It allows you to show any predefined or custom controls in its popup. Additional information about RadPopupEditor is available here: 

    Feel free to use this approach which suits your requirements best.
    I hope this information helps. If you need any further assistance please don't hesitate to contact me.
