Silverlight，旋转文本框时并非所有文本都显示

Question

我有一个自定义控件，其中有一个文本框，可以旋转，具体取决于您希望它折叠还是展开，当它折叠时，我希望文本框是垂直的，当它展开时，我希望它水平。

问题是，当它是垂直的时，文本框不会显示所有文本，我一直在寻找答案，并且我知道这与 silverlight 更新其布局的方式有关。这是我的代码

private void CollapseControl()
{
    CollapseCommand.Content = "E";            
    CollapseCommand.Margin = _btnMarginOnCollapse;

    BtnZoomIn.Visibility = Visibility.Collapsed;
    BtnZoomOut.Visibility = Visibility.Collapsed;
    ScrollViewerStackPanel.Visibility = Visibility.Collapsed;
    ZoomPanel.Visibility = Visibility.Collapsed;

    this.HorizontalAlignment = HorizontalAlignment.Left;
    this.Width = 40;

    RotateTransform nameRotateTransform = new RotateTransform();
    nameRotateTransform.Angle = 270;            
    Nametb.RenderTransform = nameRotateTransform;            
    Nametb.VerticalAlignment = VerticalAlignment.Bottom;
    Nametb.Height = Nametb.Width;
    Nametb.Width = Nametb.Height;
    Nametb.UpdateLayout();

}

一种解决方案是使用 Silverlight 工具包LayoutTransformer 控件>。

您将现有的文本块包装在 LayoutTransformer 中

        <toolkit:LayoutTransformer x:Name="Namelt" ...>
            <toolkit:LayoutTransformer.LayoutTransform>
                <RotateTransform />
            </toolkit:LayoutTransformer.LayoutTransform>
            <TextBlock x:Name="Nametb" Text="Hello World" />
        </toolkit:LayoutTransformer>

然后您的代码如下所示：-

((RotateTransform)Namelt.LayoutTransform).Angle = 270;                         
Namelt.VerticalAlignment = VerticalAlignment.Bottom;     
Namelt.Height = Nametb.Width;     
Namelt.Width = Nametb.Height;

我最近遇到了类似的问题，并提出了以下解决方案（基于 Silverlight 论坛上的帖子），这也应该有助于解决您的问题：

private void CollapseControl()
{
    CollapseCommand.Content = "E";
    CollapseCommand.Margin = _btnMarginOnCollapse;

    BtnZoomIn.Visibility = Visibility.Collapsed;
    BtnZoomOut.Visibility = Visibility.Collapsed;
    ScrollViewerStackPanel.Visibility = Visibility.Collapsed;
    ZoomPanel.Visibility = Visibility.Collapsed;

    this.HorizontalAlignment = HorizontalAlignment.Left;

    LayoutTransform lt = new LayoutTransform();
    lt.Content = Nametb;

    RotateTransform nameRotateTransform = new RotateTransform();
    nameRotateTransform.Angle = 270;

    lt.LayoutTransform = nameRotateTransform;
    lt.ApplyLayoutTransform();
    Nametb.UpdateLayout();
}

我刚刚写了以下内容，我的类似问题就解决了。

layoutTransform.VerticalAlignment = VerticalAlignment.Bottom;
layoutTransform.VerticalAlignment = VerticalAlignment.Center;
