use Regex.IsMatch("RegularExpression") to match the value.

Use the regular expression used in my above link
You can call this method on any Datagrid event which you feel is suitable after databinding event....

You should be able to use something like Decimal.TryParse, supplying the appropriate parameters. In this way, you won't have to do any special coding if your code moves to machine where the format is £2,00 (and your development machine is set up as $2.00).

For example:

Private Sub btnCheck_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCheck.Click
    Dim provider As IFormatProvider = System.Threading.Thread.CurrentThread.CurrentCulture.NumberFormat
    Dim d As Decimal

    Me.lblResult.Text = Decimal.TryParse(Me.txtInput.Text, Globalization.NumberStyles.Currency, provider, d)
End Sub

P.S.

The last parameter to Decimal.TryParse is passed ByRef, so if the call to TryParse succeeds, then the converted value will be stored in "d" (in my example). TryParse itself returns a boolean value indicating whether or not the value being tested could be converted to a Decimal type.

datagridviewcell does not store values in currency (either string, decimal, double etc) you can parse the value in the cell to check it is numeric, e.g IsNumeric(Me.DataGridView1.Item(0).Value.ToString)
