我找到了一个例子并且效果很好,如果我删除ScrollViewer
,但我需要ScrollViewer
内的图像。 TextBox
应该是图像的叠加。
在此示例中,图像不在ScrollViewer
内。有人可以建议我如何在里面添加图片吗?
<Image Grid.Column="2" HorizontalAlignment="Center" Source="/Images/Italien.png"
Stretch="None"/>
<ScrollViewer Grid.Column="2" Margin="2,2,2,2" HorizontalScrollBarVisibility="Visible"
VerticalScrollBarVisibility="Visible">
<ItemsControl ItemsSource="{Binding Tests}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas IsItemsHost="True"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Canvas.Left" Value="{Binding X}"/>
<Setter Property="Canvas.Top" Value="{Binding Y}"/>
</Style>
</ItemsControl.ItemContainerStyle>
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBox Text="123" Foreground="Aqua" Background="Transparent"
FontSize="10" TextAlignment="Justify" BorderBrush="Red"
BorderThickness="1" Width="{Binding Width}"
Height="{Binding Height}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
</Image>

我不确定我是否理解您的要求,但您可以将Image和ItemsControl添加到Panel(例如Grid),然后将Panel添加到ScrollViewer:
<ScrollViewer Grid.Column="2" Margin="2,2,2,2" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible">
<Grid>
<Image Grid.Column="2" HorizontalAlignment="Center" Source="/Images/Italien.png" Stretch="None"/>
<ItemsControl ItemsSource="{Binding Tests}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas IsItemsHost="True"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Canvas.Left" Value="{Binding X}"/>
<Setter Property="Canvas.Top" Value="{Binding Y}"/>
</Style>
</ItemsControl.ItemContainerStyle>
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBox Text="123" Foreground="Aqua" Background="Transparent" FontSize="10" TextAlignment="Justify" BorderBrush="Red" BorderThickness="1" Width="{Binding Width}" Height="{Binding Height}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
</ScrollViewer>
ScrollViewer只能有一个Child元素,所以为了能够将Image和其他元素都添加到它,你需要将它们都添加到Panel中。
编辑:如果您想将图像设置为Canvas ItemsPanel的背景,您可以将Canvas的Background属性设置为ImageBrush:
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas IsItemsHost="True">
<Canvas.Background>
<ImageBrush ImageSource="/Images/Italien.png" />
</Canvas.Background>
</Canvas>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
