In a grid, I need to manually recalculate two other columns after manually changing one column.
how can you do it in vb.net

my code is 

 Private Sub Grelha_TableControlCurrentCellValidated(sender As Object, e As GridTableControlEventArgs) Handles Grelha.TableControlCurrentCellValidated
        Dim dComissaoEmpresa As Double = 0

        Select Case ccTipo
            Case tipo.Agentes

                ' CELULA ONDE ESTOU
                Dim currentCell As GridCurrentCell = Me.Grelha.TableControl.CurrentCell
                Dim tableCellStyle As GridTableCellStyleInfo = e.TableControl.GetTableViewStyleInfo(currentCell.RowIndex, currentCell.ColIndex)

                If Not IsNothing(tableCellStyle.TableCellIdentity.Column) Then
                    Dim r As Record = Grelha.Table.CurrentRecord
                    Select Case tableCellStyle.TableCellIdentity.Column.Name
                        Case "Perc." ' - nome da coluna em que estou

                            Dim dPerc As Double = r.GetValue("Perc.") -> that's my problem. it brings the old value not the value that i put in the column

                            dComissaoEmpresa = r.GetValue("Com. Empresa")
                            r.SetValue("Vl. Comissão", dComissaoEmpresa * dPerc / 100)
                            r.SetValue("Vl.Restante", dComissaoEmpresa - (dComissaoEmpresa * dPerc / 100))
                        Case "Vl. Comissão" ' 
                        Case "Vl.Restante"
                        Case Else
                    End Select

                End If
            Case Else
        End Select
    End Sub
End Class

Hi Ricardo, 
Thanks for using Syncfusion products. 
In order to perform some computation in a column based on other columns values, the ExpressionFields can be added to the GridTableDescriptor. We already documented the details to use ExpressionFields in GridGroupingControl. Please make use of the below UG link. 
Please revert us with simple screenshot of your requirement, if we misunderstood your scenario.
