why construct new dataview instead of using defaultview of datatable in c#? what scenarios creating new dataview preferable? what advantages , disadvantages of both? var dataview = new dataview(datatable); vs var dataview = datatable.defaultview; the defaultview has advantage of being there default, name implies. additional dataviews have advantage of allowing keep several of them ready , in use in parallel . so can filter , sort 3 of them in different ways , bind 3 different controls, e.g. three datagridviews or dgv , items of comboboxcell them independently . quoting this post : a dataview view on datatable, bit sql view. allows filter , sort rows - binding windows form control. additionally, dataview can customized present subset of data datatable. capability allows have 2 controls bound same datatable, showing different versions of data.
