Question

I have a WPF DataGrid bound to a collection of Entity Framework objects that s inside a parent EF object. Something along the lines of:

<DataGrid ItemsSource="{Binding SelectedCustomer.Orders}" />

Now when I want to "delete" an Order, I don t want to actually delete it from the data source, I simply want to set its IsDeleted property to true so the data is retained.

我的问题是:我如何能够获得我的<条码>DataGrid,如果它有<条码>,不动产是真实的? 我真的希望使用具有约束力的而不是表面上。与此相仿的是:

<DataGrid ItemsSource="{Binding SelectedCustomer.Orders}" RowVisibilityPath="IsDeleted" />

遵循<代码> • 显示成员Path。我认识到,我需要改写<代码> 待删除的<>代码/代码>,但这是一个不同的议题。

Any ideas?

Answer 1

除使用收集资料外如你所述,可以通过罗皮尔:

<DataGrid.RowStyle>
    <Style TargetType="{x:Type DataGridRow}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding IsDeleted}" Value="True">
                <Setter Property="Visibility" Value="Collapsed"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</DataGrid.RowStyle>

Answer 2

<DataGrid.RowStyle>
    <Style TargetType="{x:Type DataGridRow}">
       <Setter Property="Visibility" Value="{Binding IsDeleted, Converter={StaticResource BoolToVisibility}}"/>                                     
    </Style>
</DataGrid.RowStyle>
