I created a class form with buttons to manipulate data (i.e Add, Edit, Delete, Move Record, ...)

The code I'm running is as follows:
Me.BindingContext(_MyDataSet.Tables(_MyDataTable.ToString)).Position += 1
where _MyDataSet is a property that contains the dataset name.
_MyDataTable is a property that cointains the table name.

Also if I move the record pointer in the grid by using the mouse, the record that I moved from is marked as modified.
