Load additional data to row after update

Hi,

In my DataGrid, when I update a cell in a row, a get a action sent to my server through the Data Processor. I respond with “updated” and this part works. What I want to do now is update the value of the “Modified date” cell for this row, when another field is modified. What is the correct way to do that?
I read this: viewtopic.php?f=14&t=9181 , but I didn’t quite get how to implement it. Thank you.

Sorry, i got the answer here: viewtopic.php?f=2&t=14796
