update data at server side using DataProcessor


I am using DataProcessor to update the data at server side,

I am getting the data that I updated in grid when I submit the request,

Is there any way to maintain the previous values of the row?

Because I need to update the values in DB using previous values, I have no primary key in my table.

Please suggest me in this regard…



There is no way to preserve original values, but you can provide any additional data, which will be need later , inside userdata sections


In such case the dataprocessor will send new values for cell, but it will also provide “origin” value from XML, which may contain any info, necessary to identify record in DB.
