我正在设置一系列文本框的验证规则.我宁愿不为每个TextBox创建一个新的自定义验证规则实例…… Window.Resources my:IsIntegerRule x:Key="IsIntegerRule"//Window.Resources......TextBox TextBox.Text Binding XPa
<Window.Resources> <my:IsIntegerRule x:Key="IsIntegerRule"/> </Window.Resources> ... ... <TextBox> <TextBox.Text> <Binding XPath="@num" UpdateSourceTrigger="PropertyChanged" Mode="TwoWay"> <Binding.ValidationRules> <-- WHAT IS THE EQUIVALENT OF WRITING: {StaticResource IsIntegerRule} here --> </Binding.ValidationRules> </Binding> </TextBox.Text> </TextBox>
有人可以帮忙吗?
您可以使用常规属性元素语法进行标记扩展.见 Markup Extensions and WPF XAML.它看起来像这样:<Binding.ValidationRules> <StaticResource ResourceKey="IsIntegerRule"/> </Binding.ValidationRules>
