 private ICollection createDataSource() { //create a data table to store the data for the ddl_langauge control DataTable dt = new DataTable(); //define the columns of the table dt.Columns.Add("languageTextField",typeof(string)); dt.Columns.Add("languageValueField",typeof(string)); //read the content of the xml file into a DataSet DataSet lanDS = new DataSet(); string filePath = ConfigurationSettings.AppSettings["LanguageXmlFile"]; lanDS.ReadXml(filePath); if(lanDS.Tables.Count > 0) { foreach(DataRow copyRow in lanDS.Tables[0].Rows) { dt.ImportRow(copyRow); } } DataView dv = new DataView(dt); return dv; }
