public void CreateDatatableofSelectedRows() //Get Employee ID's
        {
            //ArrayList names = new ArrayList();
            //
            //Decalre DataTable object
            DataTable _selectedRows = new DataTable();
            //Add column as here you only store one value so i have decalre only one columns
            //but you can decalre morethen as per your requirement. simply add it to DataTable
            _selectedRows.Columns.Add("Name");
            DataRow _dr;
            foreach (GridViewRow gvr in this.gridISSControl.Rows)
            {
                if (((System.Web.UI.WebControls.CheckBox)gvr.FindControl("chkSelect")).Checked == true)
                {
                    //Create new row for your DataTable
                    _dr = _selectedRows.NewRow();
                    //Add value to new rows column
                    _dr["Name"] = gvr.Cells[1].Text;
                    //Add newly row to DataTable
                    _selectedRows.Rows.Add(_dr);
                    //names.Add(gvr.Cells[1].Text);
                }
            }
            //Your database of selected rows is created use it.
            _selectedRows.AcceptChanges();
            //
            //now you can use this __selectedRows DataTable directly where you need to use
            //if you need to use this outside this method then please return that table as result of this method
            //and change return type from void to DataTable
            //
            //avoid to use another loop if you can make it done with only one loop
            //
            //this.lblError.Text = string.Empty;
            //foreach (object itm in names)
            //{
            //    //Create another  datatable here if possible..!!!!
            //}
        }
