问题描述

在我的asp.net应用程序中，我在dropdownlist中遇到问题
我想在编辑时更改下拉列表的选定值

我的代码是

DataSet _DsDetail = new DataSet();
_DsDetail = objTranDetail.GetLedgerTransactionDetail(_LedgerTransID);
_AccountLedgerID = Convert.ToInt32(_DsDetail.Tables [0] .Rows [0] ["RelatedAccountLedgerID"].ToString());
ddlDebitAccount.SelectedValue = _AccountLedgerID.ToString();



在此_AccountLedgerID获取校正后的值，但在
ddlDebitAccount.SelectedValue = _AccountLedgerID.ToString();

selectedvalue不变，包含旧值


例如:
如果_AccountLedgerID为8，则ddlDebitAccount.SelectedValue不会为8
请帮助我.....................................
