Hi Martin, I created 3 forms
Form1: tMgrDbo= class(tmseform) oDs:tmsedatasource; procedure OnEnterPanel(const sender: TObject); procedure tMgrDbo.OnenterPanel(const sender:TObject); oDs.dataset:= tdbwidgetgrid(sender).datasource.dataset; Form2: tfrmDataCli=class(tMgrDbo) ttabwidget1: ttabwidget; ttabpage1: ttabpage; ttabpage2: ttabpage; Form3: TfrmInfoCli01=class(tmseform) TDBwidget1: TDBwidget; procedure OnenterPanel(const sender: TObject); Uses frmDatacli; procedure tfrmInfoCli01.OnenterPanel(const sender: TObject); frmdataclifo.onEnterPanel(sender); The problem is: When the OnEnterPanel(sender) is fired from form3 oDs propertie is not visible in Form1? Error Segmentation fault. Watch window gives can not access memory address oDs. What is wrong ? Best Regards. Med
