[Solved] Validation before item edited

[Niranjan]

Hi,

Can someone help me to implement validation before node editing is complete?

I want to validate the edited value and if it is not proper then want to rollback to old value or want to give proper error message.

Thanks in advance.

Niranjan

Hello Niranjan,

Please take a look at the sample project I prepared for you and let me know if it helps.

Hi Tihomir Petkov,

Thanks for your reply.

The example you provided is really nice.

In my project when I add service reference I will get the classes "Employee" and "Company". So if I make changed there related to validation and then when i update the service reference the changes will be lost.

So is there any other way for validation??

Hello Niranjan,

Well, I can't think of a workaround at the moment, but I believe updating the service reference will not occur very frequently, right? To minimize the amount of overwritten code you can extract the validation logic in a static class somewhere and only add the calls to the validation methods in the setters.

Best wishes,
