How can I allow selected rows in a DataGridView (DGV) to be moved up or down in a button click. susanna.floora11-Feb-13 22:50 susanna.floora 11-Feb-13 22:50  i have datagridview whose datasource is assigned to datatable and 2 buttons. click on up button should move my row up. and click on down button should move row down. it gives error. "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
