Hi guys: Is there any way I can change these values by means of using the arow keys as right now they only change in the textboxes when I use the mouse.

Thanks

    Public Sub Get_Weights(Active_Status)
        DataGridView1.DataSource = "null"
        sDataBaseString(2) = "data source=175.16.64.3;user id=sa;password=;initial catalog=processtwo"
        Dim strConnection As String = sDataBaseString(2)
        Dim cn As SqlConnection = New SqlConnection(strConnection)
        Dim bSource As New BindingSource
        DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
        Try
            cn.Open()
            query = "select BarcodeType as Tank, Active as Active, Description as Description, ContractWeight as 'Contract Weight', ComponetWeight as 'Component Weight', WatchTolerance as 'Watch Tolerance', LimitTolerance as 'Limit Tolerance', convert(float, ComponetWeight)+convert(float, ContractWeight) as 'Target Weight' from Weights " & Active_Status
            command = New SqlCommand(query, cn)
            sda.SelectCommand = command
            sda.Fill(dbDataSet)
            bSource.DataSource = dbDataSet
            DataGridView1.DataSource = bSource
            'sda.Update(dbDataSet)
            command = New SqlCommand(query, cn)
            reader = command.ExecuteReader
        Catch ex As SqlException
            MessageBox.Show(ex.Message)
        Finally
