Silverlight 3工具包样式防止显示SL 3.0数据验证错误

如果我将SL 3.0工具包中的样式应用于我的应用程序，则内置的SL 3.0数据验证错误不会显示在应用程序编辑表单上。如果我删除了将工具箱样式应用于应用程序的代码，那么SL 3.0数据验证错误是否会按照正常的SL 3.0行为出现

还有其他人遇到过这个问题吗

任何帮助都会得到感激

经过一番研究，我终于找到了问题的解决办法。 为此，我向杰西·利伯蒂大喊一声

基本上，toolkit样式的控件模板不包含SL3.0验证工作所需的可视状态组

为了解决这个问题，我将所需的可视状态组和所需的模板标记从标准控件模板复制到toolkit控件模板

下面是复选框控件的可视状态组

<VisualStateGroup x:Name="ValidationStates">
    <VisualState x:Name="Valid"/>
    <VisualState x:Name="InvalidUnfocused">
        <Storyboard>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ValidationErrorElement" Storyboard.TargetProperty="Visibility">
                <DiscreteObjectKeyFrame KeyTime="0">
                    <DiscreteObjectKeyFrame.Value>
                        <Visibility>Visible</Visibility>
                    </DiscreteObjectKeyFrame.Value>
                </DiscreteObjectKeyFrame>
            </ObjectAnimationUsingKeyFrames>
        </Storyboard>
    </VisualState>
    <VisualState x:Name="InvalidFocused">
        <Storyboard>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ValidationErrorElement" Storyboard.TargetProperty="Visibility">
                <DiscreteObjectKeyFrame KeyTime="0">
                    <DiscreteObjectKeyFrame.Value>
                        <Visibility>Visible</Visibility>
                    </DiscreteObjectKeyFrame.Value>
                </DiscreteObjectKeyFrame>
            </ObjectAnimationUsingKeyFrames>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="validationTooltip" Storyboard.TargetProperty="IsOpen">
                <DiscreteObjectKeyFrame KeyTime="0">
                    <DiscreteObjectKeyFrame.Value>
                        <System:Boolean>True</System:Boolean>
                    </DiscreteObjectKeyFrame.Value>
                </DiscreteObjectKeyFrame>
            </ObjectAnimationUsingKeyFrames>
        </Storyboard>
    </VisualState>
</VisualStateGroup>

下面是复选框的ValidationErrorRelation的样式

<Border x:Name="ValidationErrorElement" Margin="1" Visibility="Collapsed" BorderBrush="#FFDB000C" BorderThickness="1" CornerRadius="1" ToolTipService.PlacementTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}">
    <ToolTipService.ToolTip>
        <ToolTip x:Name="validationTooltip" Template="{StaticResource ValidationToolTipTemplate}" DataContext="{Binding RelativeSource={RelativeSource TemplatedParent}}" Placement="Right" PlacementTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}">
            <ToolTip.Triggers>
                <EventTrigger RoutedEvent="Canvas.Loaded">
                    <BeginStoryboard>
                        <Storyboard>
                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="validationTooltip" Storyboard.TargetProperty="IsHitTestVisible">
                                <DiscreteObjectKeyFrame KeyTime="0">
                                    <DiscreteObjectKeyFrame.Value>
                                        <System:Boolean>true</System:Boolean>
                                    </DiscreteObjectKeyFrame.Value>
                                </DiscreteObjectKeyFrame>
                            </ObjectAnimationUsingKeyFrames>
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
            </ToolTip.Triggers>
        </ToolTip>
    </ToolTipService.ToolTip>
    <Grid Height="10" HorizontalAlignment="Right" Margin="0,-4,-4,0" VerticalAlignment="Top" Width="10" Background="Transparent">
        <Path Fill="#FFDC000C" Margin="0,3,0,0" Data="M 1,0 L5,0 A 2,2 90 0 1 7,2 L7,6 z"/>
        <Path Fill="#ffffff" Margin="0,3,0,0" Data="M 0,0 L2,0 L 7,5 L7,7"/>
    </Grid>
</Border>

您还需要将验证工具提示的控件模板放置在控件或应用程序源中。即

<ControlTemplate x:Key="ValidationToolTipTemplate">
        <Grid x:Name="Root" Margin="5,0" Opacity="0" RenderTransformOrigin="0,0">
            <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="OpenStates">
                    <VisualStateGroup.Transitions>
                        <VisualTransition GeneratedDuration="0"/>
                        <VisualTransition GeneratedDuration="0:0:0.2" To="Open">
                            <Storyboard>
                                <DoubleAnimationUsingKeyFrames Storyboard.TargetName="xform" Storyboard.TargetProperty="X">
                                    <SplineDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/>
                                </DoubleAnimationUsingKeyFrames>
                                <DoubleAnimationUsingKeyFrames Storyboard.TargetName="Root" Storyboard.TargetProperty="Opacity">
                                    <SplineDoubleKeyFrame KeyTime="0:0:0.2" Value="1"/>

Hi，我目前在验证方面遇到了完全相同的问题，你能提供一个这个东西的工作演示，或者一个到工作演示的链接吗？我遵循了你的链接，但我没有足够的带宽观看视频：/
