C#wpf未能创建自定义控件的实例

他们说，一幅画抵得上千言万语

我有一个名为

RichTextBoxEditor

的自定义控件：

以下是XAML：

我

这个控件最初是从网络中获取的，我忘了它在哪里了。但后来我修改了它的某些部分。在Designer中，它很好，但当我将它放在主窗口上时，它将如下所示：

以下是一些可能有用的信息：

提前感谢：）

编辑：

namespace WpfRichText.Ex.Controls
{

public partial class RichTextEditor : UserControl
{
    public static readonly DependencyProperty TextProperty =
      DependencyProperty.Register("Text", typeof(string), typeof(RichTextEditor),
      new PropertyMetadata(string.Empty));

    public RichTextEditor()
    {
        InitializeComponent();
    }

    public string Text
    {
        get { return GetValue(TextProperty) as string; }
        set { 
            SetValue(TextProperty, value);
        }
    }

    private void ToolStripButtonStrikeout_Click(object sender, RoutedEventArgs e)
    {
        TextRange range = new TextRange(mainRTB.Selection.Start, mainRTB.Selection.End);

        TextDecorationCollection tdc = (TextDecorationCollection)mainRTB.Selection.GetPropertyValue(Inline.TextDecorationsProperty);
        if (tdc == null || !tdc.Equals(TextDecorations.Strikethrough))
        {
            tdc = TextDecorations.Strikethrough;

        }
        else
        {
            tdc = new TextDecorationCollection();
        }
        range.ApplyPropertyValue(Inline.TextDecorationsProperty, tdc);
    }

    private void Tool_Link_Click(object sender, RoutedEventArgs e)

如果我没有弄错的话，这就是我所做的：

• 将我的自定义图像添加到项目资源（在编译时链接；资源）
• 更改了每个按钮的图像来源（粗体和斜体除外）
• 如果我还记得什么，我会更新这个部分

更多信息：

我试图复制粘贴原始XAML而不修改它。当我在主窗口中使用它时，它工作了！但是，按钮的所有图像都不会显示（粗体和斜体除外，因为它们不使用任何图像）

您还记得您修改了什么吗？您是否尝试过将其更改回原来的版本，然后修改较小的片段以查看失败的时间？您是否尝试过在谷歌上搜索确切的错误消息？“提供布拉布拉布拉布拉布拉的价值…”一个？你可能会得到很多这样的错误提示。@JarrettRobertson不知何故我找到了原始的XAML，它在CodeProject lol上。编辑了主要帖子。
