How to remove dafault nulls from the datagrid on the form?

My code is:

 Dim ds As New DataSet
        dt = ds.Tables.Add("CourseInfo")
        dt.Columns.Add("Course", GetType(String))
        dt.Columns.Add("Course Date (MMDDYY)", GetType(String))


        grdCourse.DataSource = dt
        Dim ts As New DataGridTableStyle
        ts.MappingName = "CourseInfo"
        grdCourse.TableStyles.Clear()
        grdCourse.TableStyles.Add(ts)

        ts.GridColumnStyles(0).Width = 150
        ts.GridColumnStyles(1).Width = 170

When entering the valus on the form, I see the word null in the datagrid.
How can I get rid of that?

Please help.

Thanks.

 For i = 0 To dt.Columns.Count - 1
