How do we use Json for label that has value generated ?

Question

Hi experts,

 

After thinking and trying very hard, I think I will use WebService with Json + Store Procedure to do my udpate and work flow.

 

However, I would like to know if the label is a hidden one or the label doesn't require user to enter the text but it is based on a generated no method, how do we use Json in this case ?

 

Hope to hear from someone soon.

 

And please no jquery cos I will be doing several methods in the Web Service and jquery will be too messy.
