Style.Triggers，从 WPF 移动时的 DataTrigger 问题，如何

  • 772

在 WPF 中，我使用了以下代码：

 <Button.Style>
    <Style TargetType="{interop:TypeName Button}">
        <Style.Triggers>
            <DataTrigger Value="True" Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.NormalCell}}">
                <Setter Property="Template" Value="{StaticResource NormalCellTemplate}" />
            </DataTrigger>
            <DataTrigger Value="True" Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.NulledCell}}">
                <Setter Property="Template" Value="{StaticResource NulledCellTemplate}" />
            </DataTrigger>
            <DataTrigger Value="True" Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.CurrentCell}}">
                <Setter Property="Template" Value="{StaticResource CurrentCellTemplate}" />
            </DataTrigger>
            <DataTrigger Value="True" Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.PossibleCell}}">
                <Setter Property="Template" Value="{StaticResource PossibleCellTemplate}" />
            </DataTrigger>
            <DataTrigger Value="True" Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.DeleteCell}}">
                <Setter Property="Template" Value="{StaticResource DeleteCellTemplate}" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
</Button.Style>

转移到时，UWP它变成了南瓜。我在谷歌上搜索了几个拐杖，但不知何故我不喜欢它们，而且总的来说我们与它们没有任何关系。

    试试这样：

        <Interactivity:Interaction.Behaviors>
    <Core:DataTriggerBehavior Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.NormalCell}}" Value="True">
        <Core:ChangePropertyAction PropertyName="ItemTemplate" TargetObject="{Binding ElementName=myButt}" Value="{StaticResource NormalCellTemplate}"/>
    </Core:DataTriggerBehavior>
    <Core:DataTriggerBehavior Binding="{Binding CellStatus, Converter={StaticResource CellViewStateConverter}, ConverterParameter={x:Static model1:CellState.NulledCell}}" Value="True">
        <Core:ChangePropertyAction PropertyName="ItemTemplate" TargetObject="{Binding ElementName=myButt}" Value="{StaticResource NulledCellTemplate}"/>
    </Core:DataTriggerBehavior>
</Interactivity:Interaction.Behaviors>

 <Button x:Name="myButt" />
