Dim table As DataTable = CType(DataGrid1.DataSource, DataTable) Dim row As DataRow = table.Rows(DataGrid1.CurrentCell.RowNumber) row.BeginEdit row(1) = Edit1.Text If row.HasVersion(datarowversion.Proposed) Then If row(1, DataRowVersion.Current) Is _ row(1, DataRowversion.Proposed) Then Console.WriteLine("The original and the proposed are the same") row.CancelEdit Exit Sub Else row.AcceptChanges End If Else Console.WriteLine("No new values proposed") End If End Sub
