I’m trying to find an example of a multi line user editable combobox for WPF. We’ve tried various things with a custom template but can’t make it work. The specific problem we’re trying to solve is displaying a list of addresses in a drop down where the user can type in new ones at the same time. Typing into a combobox is no problem.. multi line is killing us though.

    If we want show Textbox in ComboBox we can override the ItemTemplate of ComboBox. And to display multiline text we can set AcceptReturn=”True” for TextBox.

        <ComboBox Width="250" Height="30"  >
        <ComboBox.ItemTemplate>
            <DataTemplate>
                <TextBox AcceptsReturn="True" Width="200" Height="100"/>
            </DataTemplate>
        </ComboBox.ItemTemplate>
    </ComboBox>

    Is this what you need or am I missing something?
