WPF CheckBox style with the TextWrapping

Question

I need to apply a TextWrapping in the WPF CheckBox.

Please look at this two samples:

<CheckBox>  
  <TextBlock TextWrapping="Wrap"  
             Text="_This is a long piece of text attached to a checkbox."/>  
</CheckBox>

<CheckBox>  
  <AccessText TextWrapping="Wrap"  
              Text="_This is a long piece of text attached to a checkbox."/>  
</CheckBox>

If I use a TextBlock in the Content of the CheckBox, the check element (vertical alignment is top) and the text displays properly, but not the accelerator.

If I use an AccessText in the Content of the CheckBox, the check element displays wrong (vertical alignment is center).

How can I change the Style of the elements to display this CheckBox correct?

Answer 1

Havew you tried setting an implicit style for the AccessText, or just an AccessText style you can apply?

Here's an implicit style that would work:

    <Style x:Key="{x:Type AccessText}" 
    TargetType="{x:Type AccessText}"
    BasedOn="{x:Null}">
    <Setter Property="Foreground" Value="Black"/>
    <Setter Property="FontFamily" Value="Segoe UI"/>
    <Setter Property="FontSize" Value="12"/>
    <Setter Property="TextTrimming" Value="CharacterEllipsis"/>
    <Setter Property="TextWrapping" Value="NoWrap"/>
    <Setter Property="OverridesDefaultStyle" Value="True"/>
    <Setter Property="VerticalAlignment" Value="Top"/>
    <Setter Property="Margin" Value="5,2"/>
    <Setter Property="Text" Value="AccessText"/>
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Foreground" Value="Gray"/>
        </Trigger>
    </Style.Triggers>
</Style>

If you include this in your project the AccessText should work the way you want. If you need something else, adjust the style.

If you don't want all AccessTexts to behave this way, name the style and apply it where you use it:

<CheckBox>         
  <AccessText TextWrapping="Wrap" Style="{DynamicResource CkbxAccessTextStyle}"        
              Text="_This is a long piece of text attached to a checkbox."/>         
</CheckBox> 

Answer 2

If you combine the two you will probably get the effect you desire.

<CheckBox>
    <TextBlock>
        <AccessText TextWrapping="Wrap"  
                    Text="_This is a long piece of text attached to a checkbox."/>  
    </TextBlock>
</CheckBox>
