Hi Sudeshna,
Here i am giving you the code for your problem.
So do as you have done adding the data to the datagrid view. Now add these code for evaluation of the rowdata and its values for coloring.

<code>Dim i As Integer
        For i = 0 To DataGridView1.Rows.Count - 1
            If IsNothing(DataGridView1.Rows(i).Cells(0).Value) Then
                DataGridView1.Rows(i).DefaultCellStyle.BackColor = Color.Green
            Else
                DataGridView1.Rows(i).DefaultCellStyle.BackColor = Color.Red
            End If
        Next</code>
here the cells(0) refers to the column where the date data is entered. I think it will solve your problem.
Thank you

For Each rw As GridViewRow In dgrd_WWWH.Rows
            If String.IsNullOrEmpty(rw.Cells("date").ToString()) Then
                rw.BackColor = Drawing.Color.Green
            Else
                rw.BackColor = Drawing.Color.Red
            End If
        Next
