Hi Hengky, 

Thanks for contacting Syncfusion support. 

We have prepared sample using TabbedMDIManager and checked your query “Unable to change text of the Label which is in another form” but we were unable to reproduce the reported issue and it is working fine as expected. In this sample we have added two child forms in TabbedMDIManager and displayed each from. Please download the sample from below location, 


On further checking the reported query we have found that some developers also facing the same issue with text of Label. Invoking Refresh or Update function after changing Text in Label may help you to resolve this case. Please refer the below link 


If we have misunderstood query please get back to us with more details like sample or screenshot which replicates your requirement or modify the above sample to reproduce the issue. This would help us to provide solution at earliest. 

Regards, 
Durga S.

Hai Durga thanks for writing back... 

i have solved the problem with that. its not because of syncfusion tabbedmdimanager. 

i use this code : 
                        Dim frm = Application.OpenForms("FrmBeli")
                        If frm IsNot Nothing Then
                            If GridCari.CurrentRow.Index <> -1 Then
                                i = GridCari.CurrentRow.Index
                                CType(frm, FrmBeli).TxtKodeSupplier.Text = GridCari.Rows(i).Cells(0).Value.ToString()
                                CType(frm, FrmBeli).LblNamaSupplier.Text = GridCari.Rows(i).Cells(1).Value.ToString()
                            End If
                        End If

Best Regards 

Hengky
