Hi,
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
