重构 DataTemplate (XAML) 以减少重复
我有以下数据模板:
第一个:
<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>
第二个:
<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>
除了 {} 中的内容之外,它们 100% 相同。
有没有办法减少这里的冗余?我担心我会改变其中一处而忘记改变另一处。
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.

至于您在代码中的评论 - 我认为可以通过将
Border
的Background
设置为Transparent
来解决问题。并解决主要问题。您可能有一个描述
ContentControl
的样式,其中包含SrcField
和DestField
属性类型的 DataTemplate。然后将其绑定到Name和FieldType,并使用它的主要2个DataTemplates。像这样的事情:As for your comment in the code - i think the problem can be solved by setting the
Border
'sBackground
toTransparent
.And to the main problem. You could probably have a style that describes the
ContentControl
, which will include the DataTemplate for the type of theSrcField
andDestField
properties. Then bind in it to Name and FieldType, and use it the main 2 DataTemplates. Something like this:是的,我将创建一个具有名为 Name 和 FieldType 的公共依赖属性的用户控件,然后在 DataTemplates 中使用该控件。
Yeah, I'd create a user control with public dependency properties called Name and FieldType and then use that control in your DataTemplates.
