Question

我在网格中有图像，我想将网格的高度和宽度分别设置为图像的源高度+ 10和宽度+ 10。我写了下面的代码，但它没有用。

<Grid VerticalAlignment="Top" HorizontalAlignment="Center"> <Grid.ColumnDefinitions> <ColumnDefinition Width="{Binding ElementName=imagePreview, Path=imagePreview.Source.Width}" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions > <RowDefinition Height="{Binding ElementName=imagePreview, Path=imagePreview.Source.Height}" /> </Grid.RowDefinitions> <Image Name="imagePreview" Grid.Row="0" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Center" Stretch="None"/> </Grid>

怎么做？

Answer 1

使用Margin属性怎么样？：

<Grid VerticalAlignment="Top" HorizontalAlignment="Center" Margin="10">
    <Grid.ColumnDefinitions>
       <ColumnDefinition  Width="{Binding ElementName=imagePreview, 
           Path=imagePreview.Source.Width}" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions >
       <RowDefinition Height="{Binding ElementName=imagePreview, 
           Path=imagePreview.Source.Height}" />
    </Grid.RowDefinitions>
    <Image Name="imagePreview" Grid.Row="0" Grid.Column="0"
       VerticalAlignment="Center" HorizontalAlignment="Center" Stretch="None"/>     
</Grid>

Answer 2

您可以将代码缩减为：

 <Grid>
     <Image Name="imagePreview" Grid.Row="0" Grid.Column="0"
         VerticalAlignment="Center"
         HorizontalAlignment="Center"
         Stretch="None" Margin="10"/>
 </Grid>

在图片控件中使用保证金属性。
