Master detail gdbg sorting question

Hi I have 2 dataset's tables Master and Detail linked by dataset foreign key. I have 2 GridDataBoundGrid bounded one to Master and other to foreign key MasterDetail. All this work well BUT i need MasterDetail GDBG to be sorted on some column (saying PosInList)_without_ _user_ _intervention_ (clicking header). How can i implement this ? DefaultView - useless, datagrid ignore defaultView (i don't know why). TIA Alex

I think you can sort the master grid if you get the DataView from the CurrencyManager. CurrencyManager cm = (CurrencyManager) this.BindingContext[this.masterGrid1.DataSource, this.masterGrid1.DataMember]; DataView dv = (DataView) cm.List; dv.Sort = "ParentName desc";
