我有一个高度自定义的编辑控件，它继承了RichTextBox。我需要一种方法将Value绑定到此控件，因此我注册了一个新的DependencyProperty，但我无法像我需要的那样对其进行编码。
public static readonly DependencyProperty ValueProperty =
DependencyProperty.Register("Value", typeof(string), typeof(XliffRichCellEditor),
new PropertyMetadata(new PropertyChangedCallback(XliffRichCellEditor.OnValuePropertyChanged)));
public String Value
{
get { return (String)this.GetValue(ValueProperty); }
set { this.SetValue(ValueProperty, value); }
}
private static void OnValuePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
// Need to change Document in RichTextBox when Binding Source is changed
// But also ignore if the change comes from RichTextBox which is only updating
// the DependencyProperty. In this case Binding Source should be updated.
}
请帮忙。
