Hi,
I found some useful information regarding the updation of the updated current row record from the "Dynamics AX tools and tutorials" blog.
It may be helpful to someone.
In order to update the display options for a specific row that you updated, you can use the clearDisplayOption method on the FormDataSource class.
So, after calling
yourDS_ds.reread();
yourDS_ds.refresh();
you should call
yourDS_ds.clearDisplayOption(yourDS);
This should do the trick and update the color of the row.
