Datagrid Recalculate

I'm using the code below to sum a column in my datagrid, and it works. BUT when i delete a row and try rerunning the code i get the following error.

-Deleted row information cannot be accessed through the row.-

Code:

---

    Private Sub cmdShow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdShow.Click
        ShowBalance(DataSet11)
    End Sub    Private Sub ShowBalance(ByVal dataset As DataSet)
        Try
            Dim dataTable As DataTable = dataset.Tables(0)
            Dim Rows As Integer = dataTable.Rows.Count
            Dim Row As Integer = 0
            Dim number As Integer = 0
            While Row < Rows
                number = Convert.ToInt32(dataTable.Rows(Row)(1))
                txtTotalBalance.Text = number + Convert.ToInt32(txtTotalBalance.Text)
                Row += 1
            End While
        Catch ShowBalanceException As System.Data.OleDb.OleDbException
            MessageBox.Show(ShowBalanceException.Message)
        End Try
    End Sub

After you have deleted your row, do you update the dataset?
The process of deleting a row in a datatable simply marks the row for deletion, it does not actually delete it until you run the update command.

how do you capute the event of a row being deleted?

there is no ned to bother capturing the delete event, there is a row state property which means you can ignore any rows set for deletion.
