Validation of label

Dear All,
I would like to validate the label text,before its is set to the businessobject. Is there a way to do this? I was looking at the link , but could not get the answer,.
Thanks and Regards

Validation of labels is possible, but you’d have to implement it yourself. If you have any further questions about this I’m happy to help.

Hi Philipp,
Good to hear this. Can you please provide details of how to implement this?
