[WPF] Editable ComboBox with context menu

08/31/2012 13:19 Obilee#1

I implemented a editable combobox with wpf:

Code:

 <ComboBox IsEditable="True">
                <ComboBoxItem Content="Item1"></ComboBoxItem>
                <ComboBoxItem Content="Item2"></ComboBoxItem>
</ComboBox>

and it works fine, but now i want to add my own context menu:

Code:

<ComboBox IsEditable="True" ContextMenu="{StaticResource contextMenu}">

and here is my problem: the comobox shows the editable contextmenu with copy, paste, cut and not my own declared one.

do somebody know how to avoid that my context menu is overwritten?

PHP Code:


			
<ComboBox IsEditable="True" ContextMenuService.ShowOnDisabled="True">
    <ComboBoxItem Content="Item1"></ComboBoxItem>
    <ComboBoxItem Content="Item2"></ComboBoxItem>
</ComboBox>

Code:

<ComboBox IsEditable="True" ContextMenuService.ShowOnDisabled="True">
            <ComboBox.ContextMenu>
                <ContextMenu>
                    <MenuItem Header="test"></MenuItem>
                </ContextMenu>
            </ComboBox.ContextMenu>
            <ComboBoxItem Content="Item1"></ComboBoxItem>
            <ComboBoxItem Content="Item2"></ComboBoxItem>
        </ComboBox>

still the "cut/paste/copy" context menu visible and not my "test" context meu.
you can only see it if you right click on a select able combobox item, but i want this menu in the editable field of the context menu

du hast aber in deinem beispiel auch kein "IsEditable="True"" drinne ;) wenn ich eine normale combobox mache geht es auch ohne probleme

Ah jetzt wei� ich was du meinst.

PHP Code:


			
        <ComboBox HorizontalAlignment="Left" Height="28" Margin="10,10,0,0" Width="296" IsEditable="True" ContextMenuService.ShowOnDisabled="True" Name="combobox" Loaded="combobox_Loaded">
            <ComboBox.ContextMenu>
                <ContextMenu>
                    <MenuItem Header="test"></MenuItem>
                </ContextMenu>
            </ComboBox.ContextMenu>
            <ComboBoxItem Content="Item1"></ComboBoxItem>
            <ComboBoxItem Content="Item2"></ComboBoxItem>
        </ComboBox>

PHP Code:


			
        private void combobox_Loaded(object sender, RoutedEventArgs e)
        {
            (VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(combobox, 0), 2) as TextBox).ContextMenu = combobox.ContextMenu;
        }
