How to update specific row using checkbox?

This is what I've tried. This works for checkbox value only and all displayed data will be updated.

 Public Sub updateDGV()







    Dim id As String

    Dim cb As String

    Dim time As String

    Dim str As String

    Dim mycon As New SqlConnection(ConString)

    Try

        mycon.Open()

        For Each row As DataGridViewRow In dgv.Rows

            row.Cells(22).Value = Date.Now.ToString("MM/dd/yyyy HH:mm:ss tt")

            id = row.Cells(0).Value.ToString

            cb = row.Cells(1).Value.ToString

            time = row.Cells(22).Value.ToString

            str = "UPDATE GuardMonitoring SET EmploymentStatus =@EmpStat, 

           ModifiedBy =@ModifiedBy, ModifyDate =@ModifyDate WHERE 

            (Employee_Id =@EmpId)"





            Dim cmd As SqlCommand = New SqlCommand(str, mycon)

            cmd.Parameters.AddWithValue("@EmpId", SqlDbType.VarChar).Value = id

            cmd.Parameters.AddWithValue("@EmpStat", SqlDbType.VarChar).Value = cb

            cmd.Parameters.AddWithValue("@ModifiedBy", SqlDbType.VarChar).Value = UserPass.txtfull2.Text

            cmd.Parameters.AddWithValue("@ModifyDate", SqlDbType.VarChar).Value = time

            cmd.ExecuteNonQuery()



        Next

        mycon.Close()

    Catch ex As Exception

        showmsg.ForeColor = Color.LightCoral

        showmsg.Text = "Rows not found!"

        MsgBox(ex.Message)

    End Try



End Sub

Expected output: update only when changing the specific value of checkbox.

It should be fairly obvious that if you want to do something for a row only IF it is checked then you need an If statement in there somewhere. This is why I tell people to work out the logic they want to implement before they start writing any code to implement it. If you had done that then there would have to be some check in that logic for whether the row was checked or not, so you would have to implement that logic in your code.

        For Each row As DataGridViewRow In dgv.Rows

            If Convert.ToBoolean(row.Cells("your checkbox column name").Value) Then

                row.Cells(22).Value = Date.Now.ToString("MM/dd/yyyy HH:mm:ss tt")

                id = row.Cells(0).Value.ToString

                cb = row.Cells(1).Value.ToString
