C＃wpf无法创建自定义控件
他们说，一张图片值得千言万语。
我有一个名为RichTextBoxEditor的自定义控件：
这是XAML：

这个控制最初来自网络，我忘记了它的位置。但后来我修改了它的一些组成部分。在Designer中它很好，但是当我把它放在主窗口上时，它看起来像这样：

编辑第二名：
如果我没弄错的话就是我所做的：
- 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（Bold＆amp; Italic除外）
- 如果我还记得其他任何内容，我会更新此部分！
更多信息：
我尝试复制粘贴原始XAML而不进行修改。当我在主窗口中使用它时，它的工作原理！但是，按钮的所有图像都没有显示（Bold和Italic除外，因为它们不使用任何图像）。
RichTextEditor.xaml.cs：
namespace WpfRichText.Ex.Controls
{
/// <summary>
/// Interaction logic for BindableRichTextbox.xaml
/// </summary>
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)
{
}
}
}
