在内容中设置的 WPF DataTemplate 属性

发布于 2024-09-07 04:51:36 字数 2321 浏览 9 评论 0原文

WPF 新手,有选项卡,每个选项卡中的内容都显示在弯曲的角面板/窗口/无论什么内容中。我不确定如何执行此操作( Style、ControlTemplate ),但决定采用 DataTemplate 方式。

所以现在我有了这个 DataTemplate:

<DataTemplate x:Key="TabContentPresenter" >
    <Border Margin="10"
            BorderBrush="{StaticResource DarkColorBrush}"
            CornerRadius="8"
            BorderThickness="2"
            Grid.Row="0"
            Padding="5" 
            Background="{TemplateBinding Background}">         

        <ContentPresenter Content="{Binding}" />

    </Border>
</DataTemplate>

正如您所看到的背景属性,我不想在内容中设置背景颜色,但不知道如何设置。这里我用它。

<Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="120"/>
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>

            <ContentControl ContentTemplate="{StaticResource TabContentPresenter}" Background="White">


                <!-- Something Here -->

            </ContentControl>

            <ContentControl ContentTemplate="{StaticResource TabContentPresenter}" Grid.Row="1" Background="Blue">

                <!-- Something Here -->

            </ContentControl>

        </Grid>

这里使用 DataTemplate 是错误的还是有其他方法?

我可能可以直接在内容上设置背景,并将模板中的填充更改为内容中的边距,但在某些类似的情况下,这是行不通的,最好只设置一次。

编辑:

根据建议,我更改为 ControlTemplate 并将其放入样式中。这解决了背景问题,但产生了一个更大的问题。现在内容不会出现。我在博客此处上读到放置 targetType 可以解决但这并没有解决我的问题。代码现在看起来像这样,并且还更改了 ContentControl 以使用样式而不是模板。

<Style x:Key="TabContentPresenter" TargetType="ContentControl" >
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ContentControl">
                <Border Margin="10"
            BorderBrush="{StaticResource DarkColorBrush}"
            CornerRadius="8"
            BorderThickness="2"
            Grid.Row="0"
            Background="{TemplateBinding Background}">

                    <ContentPresenter Content="{Binding}" />

                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

New to WPF and have Tabs and in each tab the content is presented in a curved corner panel/window/whateveryouwannacallit. I wasn't sure how to do this ( Style, ControlTemplate ) but decided to go the DataTemplate way.

So now I have this DataTemplate:

<DataTemplate x:Key="TabContentPresenter" >
    <Border Margin="10"
            BorderBrush="{StaticResource DarkColorBrush}"
            CornerRadius="8"
            BorderThickness="2"
            Grid.Row="0"
            Padding="5" 
            Background="{TemplateBinding Background}">         

        <ContentPresenter Content="{Binding}" />

    </Border>
</DataTemplate>

As you can see with the the background property I wan't to set the background color at the content but Don't know how. Here I use it.

<Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="120"/>
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>

            <ContentControl ContentTemplate="{StaticResource TabContentPresenter}" Background="White">


                <!-- Something Here -->

            </ContentControl>

            <ContentControl ContentTemplate="{StaticResource TabContentPresenter}" Grid.Row="1" Background="Blue">

                <!-- Something Here -->

            </ContentControl>

        </Grid>

Is using DataTemplate wrong here or is there any other way?

I could probably set the background straight on the content and change from padding in mthe template to margin in the content but in some similiar situations that wouldn't work and it's nicer to only have to set it once.

EDIT:

As per advice I changed to ControlTemplate and also put it inside a style. This solves the Background problem but creates a bigger one. Now the content won't appear. I read on a blog here that putting a targetType solves this but it didn't solve my problem. The code looks like this now and also changed the ContentControl to use the style instead of Template.

<Style x:Key="TabContentPresenter" TargetType="ContentControl" >
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ContentControl">
                <Border Margin="10"
            BorderBrush="{StaticResource DarkColorBrush}"
            CornerRadius="8"
            BorderThickness="2"
            Grid.Row="0"
            Background="{TemplateBinding Background}">

                    <ContentPresenter Content="{Binding}" />

                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

使用 ControlTemplate 代替 DataTemplate

 <ControlTemplate  x:Key="TabContentPresenter">
        <Border Margin="10" 
                    CornerRadius="8" 
                    BorderThickness="2" 
                    Grid.Row="0" 
                    Padding="5"  
                    Background="{TemplateBinding Background}">
            <ContentPresenter Content="{Binding}"/>
        </Border>
    </ControlTemplate>

使用 Template 代替 ContentTemplate

<ContentControl  Background="Green" Template="{StaticResource  TabContentPresenter}"/>

Use ControlTemplate instead DataTemplate

 <ControlTemplate  x:Key="TabContentPresenter">
        <Border Margin="10" 
                    CornerRadius="8" 
                    BorderThickness="2" 
                    Grid.Row="0" 
                    Padding="5"  
                    Background="{TemplateBinding Background}">
            <ContentPresenter Content="{Binding}"/>
        </Border>
    </ControlTemplate>

Use Template instead of ContentTemplate

<ContentControl  Background="Green" Template="{StaticResource  TabContentPresenter}"/>

可能是因为 TemplateBinding 不适用于 DataTemplate。 查看此问题了解详细信息

即使它有效,您所需要的只是一个 ControlTemplate 而不是数据模板。

May be because TemplateBinding does not work with DataTemplate. Check this question for details.

Even if it works, all you need is a ControlTemplate and not a datatemplate.
