i have a datagridview binded with the datatable via its datasource property....

now i want to add the Amount column of the dgv and display the total amount in the textbox,if the amount is greater than a certain value then i want the cell to coloured red

so i did this code and it worked great:

Code:
Dim i, j As Integer
        For i = 0 To DataGridView1.RowCount - 1
            j += Me.DataGridView1.Rows(i).Cells("Amount").Value
        Next
        If j > 150 Then
            Me.DataGridView1.Rows(2).Cells("Amount").Style.BackColor = Color.Red
        End If
        TextBox1.Text = j.ToString
but my problem is that i want the red colour of the cell to blinkafter every 2 seconds....how to do this?

i need to handle the timer tick event for this but i am not able to do this.....

please help......

thank you
