小编Gil*_*zzi的帖子

对不起,如果标题令人困惑,但我真的不知道如何缩短我的问题.无论如何,在这里.

我正在使用WPF,实体框架和MVVM.

目前,在我的ViewModel中,我有一个属性

public Model.Document Document {get;set;} //Model.Document is an EF Entity

然后,在XAML中,我绑定到

<TextBox Text={Binding Path=Document.Title}/>

标题当然是模型上的属性.

现在我想到了以下问题:要将模型与View分开,如果我将属性添加到ViewModel就不会更好

    public string Title
    {
        get { return Document.Title; }
        set { Document.Title = value; }
    }

然后像这样绑定:

<TextBox Text={Binding Path=Title}/>

推荐哪种方式？

我有一个带有ItemsSource属性的UserControl.由于基本UserControl类没有实现ItemsSource,我必须创建自己的依赖属性,如下所示:

#region ItemsSource Dependency Property
    public static readonly DependencyProperty ItemsSourceProperty =
        DependencyProperty.Register("ItemsSource", typeof(IEnumerable), typeof(MonthViewControl),
        new PropertyMetadata(OnItemsSourceChanged));

    static void OnItemsSourceChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e)
    {
        (obj as MonthViewControl).OnItemsSourceChanged(e);
    }

    private void OnItemsSourceChanged(DependencyPropertyChangedEventArgs e)
    {
        RefreshLayout();
    }

    public IEnumerable ItemsSource
    {
        get
        {
            return (base.GetValue(ItemsSourceProperty) as IEnumerable);
        }
        set
        {
            base.SetValue(ItemsSourceProperty, value);
        }
    }

    #endregion

现在在我的ViewModel中,我有一个Events属性,它是EventItem项的ICollectionView,如下所示:

private ObservableCollection<Controls.EventCalendar.EventItem> eventItems;
    private CollectionViewSource events;
    public System.ComponentModel.ICollectionView Events
    {
        get
        {
            if (events == null)
            {
                events = new CollectionViewSource();
                events.Source = eventItems;
            }

            return events.View; …

我正在学习WPF和MVVM模式,我正在尝试构建一个类似日历的视图.所以我目前有一个6行7列的网格.第一行应该是标题,因此指定周日,如'星期一,星期二等......'我现在在MonthView.xaml中有以下内容

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="{Binding RowHeight}"/>
        <RowDefinition Height="{Binding RowHeight}"/>
        <RowDefinition Height="{Binding RowHeight}"/>
        <RowDefinition Height="{Binding RowHeight}"/>
        <RowDefinition Height="{Binding RowHeight}"/>
        <RowDefinition Height="{Binding RowHeight}"/>
        <RowDefinition Height="{Binding RowHeight}"/>
    </Grid.RowDefinitions>

    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="{Binding CellWidth}"/>
        <ColumnDefinition Width="{Binding CellWidth}"/>
        <ColumnDefinition Width="{Binding CellWidth}"/>
        <ColumnDefinition Width="{Binding CellWidth}"/>
        <ColumnDefinition Width="{Binding CellWidth}"/>
        <ColumnDefinition Width="{Binding CellWidth}"/>
        <ColumnDefinition Width="{Binding CellWidth}"/>
    </Grid.ColumnDefinitions>

    <!-- Header Row-->
    <ContentPresenter Grid.Row="0" Grid.Column="0">
        <ContentPresenter.ContentTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding DaysOfWeek[0]}"/>
            </DataTemplate>
        </ContentPresenter.ContentTemplate>
    </ContentPresenter>
    <ContentPresenter ContentTemplate="{StaticResource CalendarHeaderCellTemplate}" Grid.Row="0" Grid.Column="1" DataContext="{Binding DaysOfWeek[1]}"/>
    <ContentPresenter ContentTemplate="{StaticResource CalendarHeaderCellTemplate}" Grid.Row="0" Grid.Column="2" DataContext="{Binding DaysOfWeek[2]}"/>
    <ContentPresenter ContentTemplate="{StaticResource CalendarHeaderCellTemplate}" Grid.Row="0" …
