Dataset updates after sorting from a grid

[ctdapper]

I am able to add a new record to the dataset with the following code.
Dim i As Integer
Dim anyRow As DataRow = Me.objpagers.COMM.NewRow
Me.objpagers.COMM.Rows.Add(anyRow)
i = Me.objpagers.COMM.Count
Me.grdCOMM.CurrentRowIndex = i
grboxadd.Visible = True
Call displaycontrols(0)
tboxlastname.Focus()
buttondelete.Visible = False
i = 0
there is a control that updates the dataset on the groupbox.

The problem is if the user sorts by clicking on a column of the grid this code will not work. it does not create a new row. I get the count of the current rows displayed in the grid.
please help it you can.
