这可以实现吗？

我已经尝试过XAML，就像Private Sub Copy_Images() Dim wks as worksheet, wks2 As Worksheet Set wks = Sheets("export") Set wks2 = Sheets("HomePage") wks2.Shapes("picture").Copy wks.range("A1").Paste End Sub一样。它隐藏了我的右侧，现在我需要显示右侧边框并隐藏我的右侧边框。

我该怎么做？

已更新：

RichTextBox

以上是我的XAML。

borderthickness ="3,3,0,3"

但它不起作用。

您可以使用以下代码执行相同的操作：

myRichTextBox.BorderThickness = new Thickness(3);

然后，如果所有边框都需要具有相同的厚度，则只能使用一个数字：

<Style x:Key="MyStyleNoBorders" BasedOn="{x:Null}" TargetType="{x:Type RichTextBox}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type RichTextBox}">
                <Border x:Name="bg" BorderBrush="Yellow" BorderThickness="0,3,0,3" Background="{TemplateBinding Background}">
                    <ScrollViewer x:Name="PART_ContentHost"  IsDeferredScrollingEnabled="True" CanContentScroll="False" />
                </Border>                       
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
<Style x:Key="MyStyleBothBorders" BasedOn="{x:Null}" TargetType="{x:Type RichTextBox}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type RichTextBox}">
                <Border x:Name="bg" BorderBrush="Yellow" BorderThickness="3" Background="{TemplateBinding Background}">
                    <ScrollViewer x:Name="PART_ContentHost"  IsDeferredScrollingEnabled="True" CanContentScroll="False" />
                </Border>                       
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

修改

由于您正在使用样式，您可以定义多个样式，然后在它们之间切换：

RichTextBox

确保txtAppendValue.Style = FindResource("MyStyleNoBorders") as Style;不是太宽，不适合屏幕，否则您将无法看到边框。然后在代码中使用一个调用来改变样式：

txtAppendValue.Style = FindResource("MyStyleBothBorders") as Style;

和

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

在WPF RichTextBox代码隐藏中显示/隐藏左右边框？
