Wpf 如何正确地将图标或图像添加到Mahapp DropDownButton中的每个菜单项
我正在使用 以下是我所拥有的: 使用 具有:Wpf 如何正确地将图标或图像添加到Mahapp DropDownButton中的每个菜单项,wpf,mahapps.metro,Wpf,Mahapps.metro,我正在使用 以下是我所拥有的: 使用 具有: public class SomeDefinition { public int Id { get; set; } public string Title{ get; set; } public ICommand Command { get; set; } public string IconPath { get; set; } } 这只显示菜单上最后一个值的图像,我无
public class SomeDefinition
{
public int Id { get; set; }
public string Title{ get; set; }
public ICommand Command { get; set; }
public string IconPath { get; set; }
}
这只显示菜单上最后一个值的图像,我无法找出我缺少了什么。为什么它只显示最后一张记录的图像
我测试了所有图像,它们都写得正确,它们也确实存在,所以问题是找不到图像文件
更新
因此,我尝试使用@mm8解决方案,并将定义类更改为:
public class SomeDefinition
{
public int Id { get; set; }
public string Title{ get; set; }
public ICommand Command { get; set; }
public Image IconImage { get; set; }
}
具有xaml:
<mah:DropDownButton
Content="my button"
Icon="{DynamicResource appbar_projector_screen}"
ItemsSource="{Binding Path=MySource}">
<mah:DropDownButton.ItemContainerStyle>
<Style TargetType="MenuItem">
<Setter Property="Header" Value="{Binding Path=Title}"/>
<Setter Property="Command" Value="{Binding Path=Command}"/>
<Setter Property="CommandParameter" Value="{Binding Path=Id }"/>
<Setter Property="Icon" Value="{Binding IconImage}" />
</Style>
</mah:DropDownButton.ItemContainerStyle>
</mah:DropDownButton>
和代码隐藏:
var Image = new Bitmap(@"D:\\1.png");
MySource = new List<SomeDefinition>
{
new SomeDefinition{Id=1, Title= $@"1", Command = Command1, IconImage = Image},
new SomeDefinition{Id=2, Title= $@"2", Command = Command2, IconImage = Image},
new SomeDefinition{Id=3, Title= $@"3", Command = Command3, IconImage = Image},
new SomeDefinition{Id=4, Title= $@"4", Command = Command4, IconImage = Image},
new SomeDefinition{Id=5, Title= $@"5", Command = Command5, IconImage = Image}
};
var Image=新位图(@“D:\\1.png”);
MySource=新列表
{
新的SomeDefinition{Id=1,Title=$@“1”,Command=Command1,IconImage=Image},
新的SomeDefinition{Id=2,Title=$@“2”,Command=Command2,IconImage=Image},
新的SomeDefinition{Id=3,Title=$@“3”,Command=Command3,IconImage=Image},
新的SomeDefinition{Id=4,Title=$@“4”,Command=Command4,IconImage=Image},
新的SomeDefinition{Id=5,Title=$@“5”,Command=Command5,IconImage=Image}
};
结果是:
如何将对象转换为图像?“这仅显示菜单上最后一个值的图像”-Setter仅创建一个图像实例,只能在一个位置显示
作为一种解决方法,您可以将图像声明为非共享资源,并通过Setter中的StaticResource使用它:
<Image x:Key="StdIcon" x:Shared="False" Width="25" Height="25" Source="{Binding IconPath}" />
<Setter Property="Icon" Value="{StaticResource StdIcon}"/>
您是否尝试将图标
属性绑定到您的图标路径
源属性?:
@mm8如果我这样做,我确实会为所有菜单项显示urlPath,但我想要的是图像而不是url,这是因为我使用图像源…我应该在哪里添加图像声明?在参考资料中,在样式之前<代码>
