组合框：添加文本到第0指数

Question

我尝试添加文本“选择选项”为0个的组合框指数却显示空白

public void BindDdlPartyAccount() 
    { 
     PartyAccount objDDlBind = new PartyAccount(); 
     List<PartyAccount> ListDdlParty = new List<PartyAccount>(); 
     ListDdlParty = objDDlBind.getDDlPartyDetails(); 
     objDDlBind.selectOption = "Select Option"; 
     objDDlBind.selectOptionId = 0; 
     ListDdlParty.Insert(objDDlBind.selectOptionId, objDDlBind); 
     ddlEditPartyAcc.DataSource = ListDdlParty; 
     ddlEditPartyAcc.ValueMember = "PAId"; 
     ddlEditPartyAcc.DisplayMember = "name"; 
    } 

Answer 1

你应该用自定义对象类型添加

istDdlParty = objDDlBind.getDDlPartyDetails(); 
objDDlBind.name= "Select Option";
