图像源属性 - 内部 DataTemplate 和 UserControl.Resources - 来自不同程序集的图像
如果我不在数据模板内,则使用图像源属性就可以了。 否则他无法找到另一个名为“Images”的程序集中的图片。
XAML,有效。我可以看到由“图像”程序集持有的图像:
<UserControl x:Class="Views.ViewUserInfo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="600">
<StackPanel Orientation="Horizontal">
<StackPanel Orientation="Horizontal" Margin="0,5,0,5">
<TextBlock Text="Authorized: "/>
<TextBlock Text="{Binding Path=IsAuthorized, Mode=OneWay}" VerticalAlignment="Center"/>
<Image Width="16" Height="16" Source="/Images;Component/Img16/Ok.png" />
</StackPanel>
</StackPanel>
</UserControl>
不起作用:
<UserControl x:Class="Views.ViewUserInfo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="600">
<UserControl.Resources>
<DataTemplate DataType="{x:Type System:Boolean}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="DataTemplate has been found " />
<Image Width="16" Height="16" Source="/Images;Component/Img16/Ok.png" />
</StackPanel>
<DataTemplate.Resources>
<!--simplyfied, Triggers removed...--->
</DataTemplate.Resources>
</DataTemplate>
</UserControl.Resources>
<StackPanel Orientation="Horizontal">
<StackPanel Orientation="Horizontal" Margin="0,5,0,5">
<TextBlock Text="Authorized: "/>
<ContentPresenter Content="{Binding Path=IsAuthorized, Mode=OneWay}" VerticalAlignment="Center"/>
<!--IsAuthorized.GetType() = typeof(System.Boolean)-->
</StackPanel>
</StackPanel>
</UserControl>
他实际上在 DataTemplate 中,因为他向我显示了文本“DataTemplate 已找到”,但我看不到任何图片。 这里有什么问题吗?
Using the Image Source Property just works, if I'm not inside a DataTemplate.
Otherwise he cannot find the picture which is in another assembly named "Images".
XAML, that works. I can see the Image, holded by the "Images" assembly:
<UserControl x:Class="Views.ViewUserInfo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="600">
<StackPanel Orientation="Horizontal">
<StackPanel Orientation="Horizontal" Margin="0,5,0,5">
<TextBlock Text="Authorized: "/>
<TextBlock Text="{Binding Path=IsAuthorized, Mode=OneWay}" VerticalAlignment="Center"/>
<Image Width="16" Height="16" Source="/Images;Component/Img16/Ok.png" />
</StackPanel>
</StackPanel>
</UserControl>
Does not work:
<UserControl x:Class="Views.ViewUserInfo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="600">
<UserControl.Resources>
<DataTemplate DataType="{x:Type System:Boolean}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="DataTemplate has been found " />
<Image Width="16" Height="16" Source="/Images;Component/Img16/Ok.png" />
</StackPanel>
<DataTemplate.Resources>
<!--simplyfied, Triggers removed...--->
</DataTemplate.Resources>
</DataTemplate>
</UserControl.Resources>
<StackPanel Orientation="Horizontal">
<StackPanel Orientation="Horizontal" Margin="0,5,0,5">
<TextBlock Text="Authorized: "/>
<ContentPresenter Content="{Binding Path=IsAuthorized, Mode=OneWay}" VerticalAlignment="Center"/>
<!--IsAuthorized.GetType() = typeof(System.Boolean)-->
</StackPanel>
</StackPanel>
</UserControl>
He's actually in the DataTemplate, because he shows me the Text "DataTemplate has been found" but i cannot see any picture..
Whats the problem here?

你说你看到了文本框,那怎么可能,你的模板是空的,你的StackPanel只是你的DataTemplate中的一个资源。尝试删除
和行,或者添加您的
。
You said you see the text box, how can that be, your template is empty, your StackPanel is just a resource in your DataTemplate. Try removing the
<DataTemplate.Resources>
and</DataTemplate.Resources>
lines or maybe add your<!--simplyfied, Triggers removed...--->
.不要使用 ContentPresenter。使用内容控件。
Dont use ContentPresenter. Use ContentControl.
