That was what I was afraid for

I know, I even change all the headers with a custom class

Need it to HighLight the current row. (property of the grid: HighLightCurrentRow)
In the event that the DynamicBackColor is changed by program, I have to 'intercept' the assignment and change it,
eg grid.Columns(3).DynamicBackColor = 'rgb(255,0,0)'
is changed by the assigmethod (in case grid.HighLightCurrentRow = TRUE) to
[iif( recno(thisalias) == this.CurrentRecno, rgb(255,255,64), rgb(255,0,0))]

Simply put: I need an event to know that the DynamicBackColor of any column has changed

the rest of the code is fine, it's just the addition of 86 columns and the deletion of the 'old' 86 columns, preserving all the properties of the 'old' columns, like ColumnOrder, and the like
