Ehlib Delphi Selection contains a component introduced in an ancestor form Which can not be deleted
When I add column to grid in design time via right-click->Columns editor, I can't remove it from this place. I get error message "Selection contains a component introduced in an ancestor form Which can not be deleted". Column created in designtime can be deleted only from Structure windows (DBGridEd1->Columns). Note: Form is inerited from other form, but columns is created on the form that inherits from the base. กรณีนี้ เป็น Bug ของ Ehlib วิธีแก้เบื้องต้น ให้ลบ จาก View Object Treeview แทน
