Sort B1 DataTable - Code Inside...

Question

Hi
I hope this will help you ...
In case you know a  better way to implement this - please post your code...
[B1Listener(BoEventTypes.et_ITEM_PRESSED, false)]
        public virtual void OnAfterItemPressed(ItemEvent pVal)
            bool ActionSuccess = pVal.ActionSuccess;
            Form oForm = B1Connections.theAppl.Forms.Item(pVal.FormUID);
            if (pVal.Row < 0)
                //click on headers...
                //call sort DT according to Col.
                Grid oGrid = (Grid) oForm.Items.Item("CFLG").Specific;
                DataTable oDT = oGrid.DataTable;
                oForm.Freeze(true);
                SortDT(ref oDT , pVal.ColUID);
                oForm.Freeze(false);
        public static bool SortDT(ref DataTable oDT, string ColName)
            //Copy To System DT
            System.Data.DataTable oSysDT = new System.Data.DataTable();
            // Add Cols
            for (int iCol = 0; iCol < oDT.Columns.Count; iCol++)
                oSysDT.Columns.Add(oDT.Columns.Item(iCol).Name);
            for (int iRow = 0; iRow < oDT.Rows.Count; iRow++)
                System.Data.DataRow oRow =  oSysDT.NewRow();
                for (int iCol = 0; iCol < oDT.Columns.Count; iCol++)
                    oRow[iCol] = oDT.GetValue(iCol, iRow);
                oSysDT.Rows.Add(oRow);
            //Sort DT
            SortSystemDataTable(oSysDT, ColName);
            //Copy Sorted table to B1DT
            oDT.Rows.Clear();
            oDT.Rows.Add(oSysDT.Rows.Count);
            for (int iRowCount = 0; iRowCount < oSysDT.Rows.Count; iRowCount++)
                for (int iColCount = 0; iColCount < oSysDT.Columns.Count; iColCount++)
                    string scol = oDT.Columns.Item(iColCount).Name;
                    int icol = oSysDT.Columns.IndexOf(scol);
                    string sValue = oSysDT.Rows[iRowCount].ItemArray[icol].ToString();
                    if (oDT.Columns.Item(iColCount).Type == BoFieldsType.ft_Date)
                        if (sValue.Length > 0)
                            DateTime dDate = DateTime.Parse(sValue);
                            oDT.SetValue(iColCount, iRowCount, dDate);
                    else
                        if (sValue.Length > 0)
                            oDT.SetValue(iColCount, iRowCount, sValue);
            return true;
        private static void SortSystemDataTable(System.Data.DataTable oDT, string Sort)
            System.Data.DataTable newDT = oDT.Clone();
            int rowCount = oDT.Rows.Count;
            System.Data.DataRow[] foundRows = oDT.Select(null, Sort); // Sort with Column name
            for (int i = 0; i < rowCount; i++)
                object[] arr = new object[oDT.Columns.Count];
                for (int j = 0; j < oDT.Columns.Count; j++)
                    arr[j] = foundRows<i>[j];
                System.Data.DataRow data_row = newDT.NewRow();
                data_row.ItemArray = arr;
                newDT.Rows.Add(data_row);
            //clear the incoming dt
            oDT.Rows.Clear();
            for (int i = 0; i < newDT.Rows.Count; i++)
                object[] arr = new object[oDT.Columns.Count];
                for (int j = 0; j < oDT.Columns.Count; j++)
                    arr[j] = newDT.Rows<i>[j];
                System.Data.DataRow data_row = oDT.NewRow();
                data_row.ItemArray = arr;
                oDT.Rows.Add(data_row);
Enjoy,
J.
