Question

I have a ContextMenu defined on a Datagrid but want to bind submenu items to a collection on my viewmodel. Can anybody suggest how this should be done?

The following is a simple example of what I’m trying to achieve, BUT I want “Test1”, “Test2” to come from a collection on my viewmodel, not hardcoded. I know how to bind my collection to the whole ContextMenu, but not how to bind it to just the one submenu…

<ContextMenu>
    <MenuItem Header="Add to">
        <MenuItem Header="Test1" />
        <MenuItem Header="Test2" />
    </MenuItem>
    <MenuItem Header="Remove from All" />
</ContextMenu>

I’m using 3.5 SP1 and the WPF Toolkit.

Guess I should have experimented more. Turns out this was relatively simple:

<my:DataGrid.ContextMenu>
    <ContextMenu>
        <MenuItem Header="Add to" ItemsSource="{Binding MyItems}">
            <MenuItem.ItemTemplate>
                <DataTemplate>
                    <MenuItem CommandTarget="{Binding}" Click="AddClick">
                        <MenuItem.Header>
                            <TextBlock>
                            <TextBlock.Text><Binding StringFormat="Add to {0}" /></TextBlock.Text>
                            </TextBlock>
                        </MenuItem.Header>
                    </MenuItem>
                </DataTemplate>
            </MenuItem.ItemTemplate>
        </MenuItem>
        <MenuItem Header="Remove from All" />
    </ContextMenu>
</my:DataGrid.ContextMenu>
