You can do loops like this::

Dim intRowCount as Integer
Dim decPrice as Decimal = 0

'dtTable is a DataTable in your dataset that is binded in your datagridview

Do until intRowCount = dtTable.Rows.Count
            decPrice = decPrice + CDec(dtTable.Rows(intRowCount).Item(4))
            'Were Item(4) is your column named  PRICE

            If intRowCount <> dtTable.Rows.Count - 1 Then
                       intRowCount = intRowCount + 1
            Else
                       Exit Do
            End If
Loop

TextBox1.Text = format(decPrice, "#,##0.#0")


thats all....... hope this could help

-where should I write this code?
I assume you a have a button that would trigger the calculation event. And the code provided you should be in that code block.

-is it in same textbox?
Probably yes? That was just an example if your using other TextBox name then set to the respective textbox!

maybe you can submit you partial code and feed me more of what your trying to do: :-)

sorry for late,
I don't have a button to calculate the event,
I put a textbox under the datagridview to calculate the total amount of the price column,

when I tried your code, it doesn't do that, it just calculate the rows of the datagrid
