Kevin,
I am getting IndexOutOfRange exception in mmDataGrid.RowChangedHandler

if (this.IsSelected(e.LastRow)){ <-- Here
this.UnSelectRow(e.LastRow);
this.SelectRow(e.CurrentRow);
}

To reproduce:
1. Debug/Exceptions/CLR Exceptions - Break into debugger
2. Run sample application and go to Lists/Employee
3. Hit new button

Two things are not quite right:
1. CurrentRow is set to the last row (as the matter of fact the first row was selected at the very beginning, not the last)
2. LastRow has value of -1 and IsSelected method does not like that

Regards,
Nick Chakarov
