设置“属性”；在验证器上
我在数据网格列中的每个单元格上使用 NumberValidator。源设置为数据网格的 dataProvider 但属性是问题。我不能只说“文本”，因为我使用 labelFunction 来检索属性，因为它嵌套在另一个对象内。
有办法解决这个问题吗？我需要创建自己的自定义验证器吗？我希望不会。任何提示表示赞赏。
谢谢！

I'm using a NumberValidator on each cell in a column on a datagrid. The source is set to the datagrid's dataProvider but the property is the problem. I can't just say 'text' because I use a labelFunction to retrieve the property because it's nested inside another object.
Any way to get around this? Am I going to need to create my own custom validator? I hope not. Any tips are appreciated.
Thanks!

这里的解决方案是使用
source和property值的正确组合。你走在正确的轨道上。对于
source属性，文档是这样说的：因此，在您的情况下，您可能希望使您的
source属性字符串更长一些，以深入到包含要验证的属性的项目中。也许：那么您要验证的属性将是：
The solution here is to use the proper combination of
sourceandpropertyvalues. You were on the right track.For the
sourceproperty the documentation says this:So in your case, you would have wanted to make your
sourceproperty string a bit longer, something that reached down into the item that contained the property to validate. Perhaps:Then your property to validate would simply be:
