UserControl 中的圆角未显示

Rounded Corners in UserControl not showing

我正在尝试让我的 UserControl 显示圆角。

这是我的标记:

<Border CornerRadius="10" Padding="5" HorizontalAlignment="Center" VerticalAlignment="Center" >
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="50" />
            <RowDefinition Height="20" />
            <RowDefinition Height="25" />
            <RowDefinition Height="25" />
            <RowDefinition Height="25" />
            <RowDefinition Height="25" />
            <RowDefinition Height="50" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="10" />
            <ColumnDefinition Width="220" />
            <ColumnDefinition Width="10" />
        </Grid.ColumnDefinitions>
        <Grid.Background>
            <ImageBrush ImageSource="{StaticResource NavyBlueGround}" />
        </Grid.Background>
        <Label Grid.Column="1" Grid.Row="0"  Style="{StaticResource GelTitle}"   Content="Customer Search" VerticalAlignment="Bottom" HorizontalAlignment="Center"/>
        <Label Grid.Row="1" Grid.Column="1" Style="{StaticResource GelCaption}"  Content="Enter Customer First Name" VerticalAlignment="Bottom" />
        <TextBox  Grid.Row="2" Grid.Column="1" Name="txtForeName"  Background="White" VerticalContentAlignment="Center"/>
        <Label Grid.Row="3" Grid.Column="1" Style="{StaticResource GelCaption}"  Content="Enter Customer Last Name" VerticalAlignment="Bottom" />
        <TextBox Name="txtSurname" Grid.Column="1" Grid.Row="4"  FontSize="14" Text="hello" VerticalContentAlignment="Center" VerticalAlignment="Stretch" HorizontalContentAlignment="Center" />
        <Button Name="btnCustomerSearch" Grid.Column="1" Grid.Row="5" Style="{StaticResource GelButton}" Content="Search" Click="btnCustomerSearch_Click" VerticalAlignment="Center" />
    </Grid>
</Border>

这是它的样子:

与其将背景用于网格,不如将其用于边框。

<Border CornerRadius="10" Padding="5" HorizontalAlignment="Center" VerticalAlignment="Center" >
    <Border.Background>
        <ImageBrush ImageSource="{StaticResource NavyBlueGround}" />
    </Border.Background>

编辑:这个问题的原因是边框(当 padding=5 时)将其子元素的边距设置为 5 个像素。同时定义 CornerRadius 设置网格的边距更进一步。

因此 Grid(及其背景)的边界不是出现圆角的地方。

你肯定有别的事情要发生。我使用 UserControl 将您的代码粘贴到一个新项目中,它呈现得很好。

如果新项目不适合您,您能否提供更多详细信息,并比较差异以帮助解决问题?
