AdornerDecorator 和制表位问题

我正在使用 IDataErrorInfo 来验证并指示文本框中的错误。 我发现我必须为文本框点击一次,为装饰装饰器点击一次。

我有一个错误模板:

<ControlTemplate x:Key="ErrorTemplate">
        <StackPanel KeyboardNavigation.IsTabStop="False" >
        <Border KeyboardNavigation.IsTabStop="False"  BorderBrush="Red" BorderThickness="1" Padding="2" CornerRadius="2">
            <AdornedElementPlaceholder KeyboardNavigation.IsTabStop="False" />
        </Border>
        </StackPanel>                
    </ControlTemplate>

文本框模板:

<Style x:Key="TextBoxInError" TargetType="{x:Type TextBox}">
        <Setter Property="KeyboardNavigation.TabNavigation" Value="None"/>
        <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
        <Setter Property="Margin" Value="0,5,0,5"/>
        <Setter Property="AllowDrop" Value="true"/>
        <Setter Property="HorizontalContentAlignment" Value="left"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TextBox}">
                    <Grid  KeyboardNavigation.IsTabStop="False" >
                        <Border  KeyboardNavigation.IsTabStop="False" x:Name="Border" Background="{DynamicResource WindowBackgroundBrush}" BorderBrush="{DynamicResource SolidBorderBrush}" BorderThickness="1" Padding="2" CornerRadius="2">
                            <ScrollViewer IsTabStop="False" Margin="0" x:Name="PART_ContentHost" Style="{DynamicResource SimpleScrollViewer}" Background="{TemplateBinding Background}"/>
                        </Border>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="Validation.HasError" Value="true">
                            <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors), Converter={StaticResource errorConverter}}"/>
                        </Trigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="Gray"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

并声明一个如下所示的文本框:

<AdornerDecorator  KeyboardNavigation.IsTabStop="False" >
<TextBox Margin="5,5,5,3" x:Name="txtName" IsEnabled="{Binding EditMode}" Validation.ErrorTemplate="{StaticResource ErrorTemplate}"
 Text="{Binding ApplicationName, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=True, ValidatesOnDataErrors=True}" 
 Height="25" MaxLength="50" MaxLines="1" Style="{StaticResource TextBoxInError}"/>
 </AdornerDecorator>

如果装饰器是如上所述的圆形文本框,那么我按一次标签键离开文本框,然后按一次标签键离开“装饰”(看起来)如果我在文本框堆栈面板周围有装饰器,然后我为文本框每个选项卡一次,然后必须依次返回所有“装饰”。 当通过装饰选项卡时,焦点集中在控件模板中定义的红色边框上..

有什么想法吗?

谢谢

I am using IDataErrorInfo to validate and indicate errors in my text boxes. I am finding I have to tab once for the text box and once for the adornerdecorator.

I have an error template:

<ControlTemplate x:Key="ErrorTemplate">
        <StackPanel KeyboardNavigation.IsTabStop="False" >
        <Border KeyboardNavigation.IsTabStop="False"  BorderBrush="Red" BorderThickness="1" Padding="2" CornerRadius="2">
            <AdornedElementPlaceholder KeyboardNavigation.IsTabStop="False" />
        </Border>
        </StackPanel>                
    </ControlTemplate>

a textbox template:

<Style x:Key="TextBoxInError" TargetType="{x:Type TextBox}">
        <Setter Property="KeyboardNavigation.TabNavigation" Value="None"/>
        <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
        <Setter Property="Margin" Value="0,5,0,5"/>
        <Setter Property="AllowDrop" Value="true"/>
        <Setter Property="HorizontalContentAlignment" Value="left"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TextBox}">
                    <Grid  KeyboardNavigation.IsTabStop="False" >
                        <Border  KeyboardNavigation.IsTabStop="False" x:Name="Border" Background="{DynamicResource WindowBackgroundBrush}" BorderBrush="{DynamicResource SolidBorderBrush}" BorderThickness="1" Padding="2" CornerRadius="2">
                            <ScrollViewer IsTabStop="False" Margin="0" x:Name="PART_ContentHost" Style="{DynamicResource SimpleScrollViewer}" Background="{TemplateBinding Background}"/>
                        </Border>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="Validation.HasError" Value="true">
                            <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors), Converter={StaticResource errorConverter}}"/>
                        </Trigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="Gray"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

and declare a text box like this:

<AdornerDecorator  KeyboardNavigation.IsTabStop="False" >
<TextBox Margin="5,5,5,3" x:Name="txtName" IsEnabled="{Binding EditMode}" Validation.ErrorTemplate="{StaticResource ErrorTemplate}"
 Text="{Binding ApplicationName, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=True, ValidatesOnDataErrors=True}" 
 Height="25" MaxLength="50" MaxLines="1" Style="{StaticResource TextBoxInError}"/>
 </AdornerDecorator>

If the adorner is round one text box as above then I tab once to leave the text box and once to leave the 'adornment' (it seems) If I have the adorner around a stackpanel of text boxes then I tab once each for the text boxes then have to go back through all the 'adornments' in turn. When tabbing through the adornments the focus goes on the red border defined in the control template..

any ideas?

thanks

将其添加到窗口的资源部分:

<Style TargetType="{x:Type Control}">
    <Setter Property="Focusable" Value="False"/>
</Style>

有关详细信息,请参阅我的博客:http://www.nbdtech.com/blog/archive/2008/05/25/WPF-Problems-with-Keyboard-Focus-When-Using-Validation .aspx

Add this to the window's resources section:

<Style TargetType="{x:Type Control}">
    <Setter Property="Focusable" Value="False"/>
</Style>
