装订影像清单 [英] Binding A List of Images

问题描述

我试图将图像列表(List)绑定到StackPanel，我试图使用< >分隔这些图像，但遗憾的是它不起作用.有人知道为什么吗? (我是wpf..sry的菜鸟)

I was trying to bind a list of images (List) to a StackPanel, I tried to separate those Images by using <Separator> but sadly it's not working. Anyone has a clue why? (i'm kinda rookie on wpf..so sry)

我的代码: 后面的代码:

My Code: Code Behind:

            List<Image> v2 = new List<Image>();
        for (int i = 0; i < 10; i++)
        {
            Image v2image = new Image();
            v2image.BeginInit();

            v2image.Source = new BitmapImage(new Uri("http://static.lolskill.net/img/champions/64/xayah.png"));
            v2image.Width = 40;
            v2image.Height = 40;
            v2.Add(v2image);
        }

        BlueTeam.ItemsSource = v2;

XAML:

<Window x:Class="FML.MainWindow"

<Grid>
    <ItemsControl Grid.Column="0" x:Name="BlueTeam">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="Horizontal" >

                </StackPanel>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Vertical" >
                    <Image Source="{Binding v2image.Source}"></Image>
                    <Separator Opacity="0" Height="20" Width="20"/>
                </StackPanel>
            </DataTemplate>
        </ItemsControl.ItemTemplate>   
    </ItemsControl>
</Grid>

请帮我:D 顺便说一句:图像也很小.他们不是40宽度\高度

Ty for helping me :D btw: The Images are very small aswell. they're not 40 Width\Height

它应该是这样工作的: http://imgur.com/a/bZbLf (有效当我正在使用仅具有图像的课程时

edit: This is how it supposed to work: http://imgur.com/a/bZbLf (It works when I'm using a class who has only Image)

这是它的工作方式: http://imgur.com/a/uptlo

推荐答案

您不应使用List<Image>，而应使用List<ImageSource>:

You should not have a List<Image>, but a List<ImageSource> instead:

var v2 = new List<ImageSource>();

for (int i = 0; i < 10; i++)
{
    v2.Add(new BitmapImage(
        new Uri("http://static.lolskill.net/img/champions/64/xayah.png")));
}

BlueTeam.ItemsSource = v2;

然后您将在ItemTemplate中声明一个具有固定大小的Image控件，并通过Source="{Binding}"将其直接绑定到collection元素:

You would then declare an Image control with a fixed size in the ItemTemplate and bind it directly to the collection element, by Source="{Binding}":

<ItemsControl.ItemTemplate>
    <DataTemplate>
        <Image Source="{Binding}" Width="40" Height="40" Margin="10"/>
    </DataTemplate>
</ItemsControl.ItemTemplate>   

不确定分隔符应该做什么.在上面的示例中，我仅设置了Image的Margin属性.

Not sure what the Separator was supposed to do. In the example above, I've simply set the Image's Margin property.
