when the data goes to gridview i am trying to change how the data is displayed in the third column. so far i can get the data formated as i want in
textbox5.text the porblem is getting it back in to gridview column 3 on all rows.

Dim i As Integer

Do While dr.Read()

Dim str As String

TextBox4.Text = dr.Item("cardnum").ToString()
str = TextBox4.Text
TextBox5.Text = "************" & str.Substring(12, 4)
GridView1.Rows(i).Cells(2).Text = TextBox5.Text

Loop
