Question How to count rows in datagridview

[jimmy6]

Hi everybody....still new to vb.net

I have a Windows form that has a datagridview on it. I populate it with records from a database. I have a checkbox on each row. Then I have a textbox on the form outside of the datagridview. Each time a checkbox is checked I want to count it and show it in the text box. Each time a checkbox is unchecked I want it to subtract the count.

Can anybody help?

        Dim counter As Integer = 0
        For Each dr As DataGridViewRow In DataGridView1.Rows
            If dr.Cells("your_checkbox_column_name").Value = True Then
                counter += 1
            End If
        Next
        Me.OutsideTextBox.Text = counter.ToString
