Hi,



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…



/Thanks

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


       a1
       a2
       a3
       a1^a2^a3



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.
