Hi, Try this code: // Create the `DataTable` structure according to your data source DataTable table = new DataTable(); table.Columns.Add( "FileNumber" , typeof ( int )); table.Columns.Add( "ShiftDate" , typeof (DateTime)); table.Columns.Add( "TimeCreated" , typeof (DateTime)); table.Columns.Add( "Remarks" , typeof ( string )); // Iterate through data source object and fill the table foreach (var item in CollectionUserData) { table.Rows.Add(item.FileNumber, item.ShiftDate, item.TimeCreated, item.Remarks); }
