are there any Validation Controls in WPF controls just like Validation Controls in ASP.net

Question

I've created a simple form in WPF. I have worked on ASP.NET previously, so I'm wondering if there are 'Validation Controls' in WPF that are similar to ASP.NET, or if I need to manually validate my fields.

Thanks.

Answer 1

sure, you can easily do this. What you want is IDataErrorInfo interface.
here is an example.

Answer 2

If you are using Binding, here's a good post on Stackoverflow

Quickly, you want something like that :

<TextBox Text="{Binding Age, ValidatesOnDataErrors=True}" />

And then with DataAnnotations you specify your rules. Then you use the

string IDataErrorInfo.this[string columnName]

function to validate. I use that all accross my application.
