我正在使用IDataErrorInfo來驗證並在我的文本框中指出錯誤。我發現我必須爲文本框選擇一次,併爲adornerdecorator選擇一次。AdornerDecorator和製表符問題
我有一個錯誤的模板:
<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>
一個文本框模板:
<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>
,並宣佈這樣一個文本框中:
<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>
如果裝飾器是圓的一個文本框如上,然後我選擇一次離開文本框,一次離開'裝飾'(看起來)如果我有裝飾者圍繞一個文本框的堆疊面板,然後我爲每個文本框選擇一次,然後必須依次返回所有'裝飾物'。當穿過裝飾品時,焦點集中在控制模板中定義的紅色邊框上。
任何想法?
感謝
太棒了!感謝這一直使我發瘋 - 將閱讀博客的興趣:-) – Trev 2008-12-10 09:25:34
