>>>>>This is pretty much the same what I do as well, except I do not have a textbox that is directly bound to the controlsource. I highjack the Refresh method on the control to display the data, but when executing the refresh it changes the value of the controls for all rows. I think the grid expects a textbox with a controlsource to display the data.

If you want to go with the Dynamic properties, then I suggest to try Fabio's solution of using DynamicFontBold (or Strike) and calling refresh method of the column. I used that idea a lot in the past, it is simple way to achieve desired functionality.

You are trying to combine a numeric value and a string. Try
THIS.txt.ControlSource = THIS.ControlSource/10
Or
THIS.txt.ControlSource = (THIS.ControlSource) + "/10")
