Refactor DataTemplate (XAML) to reduce duplication - wpf

Question

I have the following datatemplates:
First One:
<DataTemplate DataType="{x:Type WIAssistant:DestinationField}">
<ContentControl Margin="5" MinWidth="60" MinHeight="70" >
<Border BorderThickness="2" BorderBrush="Black" CornerRadius="5">
<!--This text block seems un-needed. But it allows the whole control to be dragged. Without it only the border and the
text can be used to drag the control.-->
<TextBlock>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock FontWeight="Bold" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="10"
Text="{Binding DestField.Name}"/>
<TextBlock Grid.Row="1" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="10"
Text="{Binding DestField.FieldType}"/>
</Grid>
</TextBlock>
</Border>
</ContentControl>
</DataTemplate>
Second One:
<DataTemplate DataType="{x:Type WIAssistant:SourceField}">
<ContentControl Margin="5" MinWidth="60" MinHeight="70" >
<Border BorderThickness="2" BorderBrush="Black" CornerRadius="5">
<!--This text block seems un-needed. But it allows the whole control to be dragged. Without it only the border and the
text can be used to drag the control.-->
<TextBlock>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock FontWeight="Bold" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="10"
Text="{Binding SrcField.Name}"/>
<TextBlock Grid.Row="1" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="10"
Text="{Binding SrcField.FieldType}"/>
</Grid>
</TextBlock>
</Border>
</ContentControl>
</DataTemplate>
They are 100% identical except for the stuff in the {}.
Is there a way to reduce the redundancy here? I fear I will make a change in one and forget to change the other.

Answer 1

As for your comment in the code - i think the problem can be solved by setting the Border's Background to Transparent.
And to the main problem. You could probably have a style that describes the ContentControl, which will include the DataTemplate for the type of the SrcField and DestField properties. Then bind in it to Name and FieldType, and use it the main 2 DataTemplates. Something like this:
<Style x:Key="SomeStyle" TargetType="ContentControl">
<Setter Property="Margin" Value="5" />
<Setter Property="MinWidth" Value="60" />
<Setter Property="MinHeight" Value="70" />
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate DataType=...> <!-- type of the `SrcField` and `DestField` properties -->
<Border Background="Transparent" BorderThickness="2" BorderBrush="Black" CornerRadius="5">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock FontWeight="Bold" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="10"
Text="{Binding Name}"/>
<TextBlock Grid.Row="1" TextWrapping="Wrap" HorizontalAlignment="Center" Margin="10"
Text="{Binding FieldType}"/>
</Grid>
</Border>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
<DataTemplate DataType="{x:Type WIAssistant:DestinationField}">
<ContentControl
Style="{StaticResource SomeStyle}"
Content="{Binding DestField}"
/>
</DataTemplate>
<DataTemplate DataType="{x:Type WIAssistant:SourceField}">
<ContentControl
Style="{StaticResource SomeStyle}"
Content="{Binding SrcField}"
/>
</DataTemplate>

Answer 2

Yeah, I'd create a user control with public dependency properties called Name and FieldType and then use that control in your DataTemplates.
