这将取决于验证的复杂性。对于一个简单的控件，必须有一个值，您可以执行以下操作：

<UI...>
 <Dialog...>
  <Control Id="Next"...>  
   <Publish Event="SpawnDialog" Value="ErrorsDlg">Not SomeProperty</Publish>
   <Publish Event="NewDialog" Value="NextDialog">Property</Publish>
  </Control>
 </Dialog>
</UI>

其中 ErrorsDlg 是您创建的类似于 MessageBox 样式对话框的对话框。如果您有更复杂的验证，您可以编写一个自定义操作来读取属性、评估规则并设置一个标志以及要显示的错误消息。那看起来更像是这样的：

<UI...>
 <Dialog...>
  <Control Id="Next"...>  
   <Publish Event="DoAction" Value="ValidateCA">1</Publish>
   <Publish Event="SpawnDialog" Value="ErrorsDlg">Not DataValid</Publish>
   <Publish Event="NewDialog" Value="NextDialog">DataValid</Publish>
  </Control>
 </Dialog>
</UI>

It's going to depend on the complexity of your validation. For a simple one control must have a value you could do something like:

<UI...>
 <Dialog...>
  <Control Id="Next"...>  
   <Publish Event="SpawnDialog" Value="ErrorsDlg">Not SomeProperty</Publish>
   <Publish Event="NewDialog" Value="NextDialog">Property</Publish>
  </Control>
 </Dialog>
</UI>

Where ErrorsDlg is a Dialog that you create to resemble a MessageBox style dialog. If you have more complicated validation you can write a custom action that reads properties, evaluates rules and sets a flag along with an error message to be displayed. That would look more like this:

<UI...>
 <Dialog...>
  <Control Id="Next"...>  
   <Publish Event="DoAction" Value="ValidateCA">1</Publish>
   <Publish Event="SpawnDialog" Value="ErrorsDlg">Not DataValid</Publish>
   <Publish Event="NewDialog" Value="NextDialog">DataValid</Publish>
  </Control>
 </Dialog>
</UI>
