XMLParseException使用DatateMplate中的绑定在使用非弦乐键访问Ressource时

发布于 2025-01-27 06:37:29 字数 1053 浏览 3 评论 0原文

我有一个用于列表视图的datatemplate。
scriptAded是枚举。
错误来自stackpanel背景属性，因为如果我将其删除，则可以工作。
我的目的是根据建议的属性（也是ScriptAdatiend类型）访问其中一个刷子。

当我运行程序时，将抛出此例外：

system.windows.markup.xamlparseexception＆nbsp;：'a“ binding''无法在类型为“ resourcectionary”类型的'deferrableContent'属性上设置。只能在依赖项的依赖项上设置“绑定”。

<DataTemplate>
    <DataTemplate.Resources>
        <SolidColorBrush x:Key="{x:Static logic:ScriptAdvised.Yes}" Color="Green" Opacity="0.15"/>
        <SolidColorBrush x:Key="{x:Static logic:ScriptAdvised.Limited}" Color="Yellow" Opacity="0.15"/>
        <SolidColorBrush x:Key="{x:Static logic:ScriptAdvised.No}" Color="Red" Opacity="0.15"/>
    </DataTemplate.Resources>
    <StackPanel Background="{StaticResource {Binding Advised}}" Orientation="Horizontal">
        <CheckBox/>
        <TextBlock Text="{Binding Name}"/>
    </StackPanel>
</DataTemplate>

我不明白，因为我的应用程序中没有任何明确的资源计算。

原文

I have a DataTemplate in a style for ListViews.
ScriptAdvised is an enumeration.
The error comes from the StackPanel background attribute because if I remove it then it works.
My objective here is to access one of the brushes according to the Advised property (which is also of the ScriptAdvised type).

When I run my program, this exception is thrown :

System.Windows.Markup.XamlParseException : 'A 'Binding' cannot be set on the 'DeferrableContent' property of type 'ResourceDictionary'. A 'Binding' can only be set on a DependencyProperty of a DependencyObject.'

<DataTemplate>
    <DataTemplate.Resources>
        <SolidColorBrush x:Key="{x:Static logic:ScriptAdvised.Yes}" Color="Green" Opacity="0.15"/>
        <SolidColorBrush x:Key="{x:Static logic:ScriptAdvised.Limited}" Color="Yellow" Opacity="0.15"/>
        <SolidColorBrush x:Key="{x:Static logic:ScriptAdvised.No}" Color="Red" Opacity="0.15"/>
    </DataTemplate.Resources>
    <StackPanel Background="{StaticResource {Binding Advised}}" Orientation="Horizontal">
        <CheckBox/>
        <TextBlock Text="{Binding Name}"/>
    </StackPanel>
</DataTemplate>

I don't understand because I don't have any explicit ResourceDictionaries in my application.

使用样式与dataTriggers使用background基于的值。这样的事情：

<DataTemplate>
    <DataTemplate.Resources>
        <SolidColorBrush x:Key="Yes" Color="Green" Opacity="0.15"/>
        <SolidColorBrush x:Key="Limited" Color="Yellow" Opacity="0.15"/>
        <SolidColorBrush x:Key="No" Color="Red" Opacity="0.15"/>
    </DataTemplate.Resources>
    <StackPanel Orientation="Horizontal">
        <StackPanel.Style>
            <Style TargetType="StackPanel">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Advised}" Value="{x:Static logic:ScriptAdvised.Yes}">
                        <Setter Property="Background" Value="{StaticResource Yes}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding Advised}" Value="{x:Static logic:ScriptAdvised.Limited}">
                        <Setter Property="Background" Value="{StaticResource Limited}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding Advised}" Value="{x:Static logic:ScriptAdvised.No}">
                        <Setter Property="Background" Value="{StaticResource No}" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </StackPanel.Style>
        <CheckBox/>
        <TextBlock Text="{Binding Name}"/>
    </StackPanel>
</DataTemplate>

Use a Style with DataTriggers to set the Background based on the value of Advised. Something like this:

<DataTemplate>
    <DataTemplate.Resources>
        <SolidColorBrush x:Key="Yes" Color="Green" Opacity="0.15"/>
        <SolidColorBrush x:Key="Limited" Color="Yellow" Opacity="0.15"/>
        <SolidColorBrush x:Key="No" Color="Red" Opacity="0.15"/>
    </DataTemplate.Resources>
    <StackPanel Orientation="Horizontal">
        <StackPanel.Style>
            <Style TargetType="StackPanel">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Advised}" Value="{x:Static logic:ScriptAdvised.Yes}">
                        <Setter Property="Background" Value="{StaticResource Yes}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding Advised}" Value="{x:Static logic:ScriptAdvised.Limited}">
                        <Setter Property="Background" Value="{StaticResource Limited}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding Advised}" Value="{x:Static logic:ScriptAdvised.No}">
                        <Setter Property="Background" Value="{StaticResource No}" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </StackPanel.Style>
        <CheckBox/>
        <TextBlock Text="{Binding Name}"/>
    </StackPanel>
</DataTemplate>
