[删除幼稚的txtspeak请求]如何绑定下拉列表 [英] [childish txtspeak begging removed] how to bind drop down list

问题描述

我有一个像这样的下拉列表:-

i have a drop down list like this:-

<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="AccessDataSource2"
    DataTextField="type" DataValueField="type" Style="z-index: 112; left: 90px; position: absolute;
    top: 33px">

我想在用户更新数据库后更新其信息
我已经尝试过此代码，但在关闭页面并重新打开后，下拉列表更新却没有任何作用，但是在没有任何作用的情况下:

and i want to update its information after a user updates the data base
already tries this codes nothing working after i close the page and reopen it the dropdownlist updates but during the working nothing:

this.AccessDataSource2.DataBind();
this.DropDownList1.DataBind();

推荐答案

您是否尝试过:(鉴于您的问题尚不完全清楚，请大猜一下.)

Have you tried: (Big guess given that your question is not entirely clear).

if (!IsPostBack)
{
    // code...
}

this.AccessDataSource2.DataBind();
this.DropDownList1.DataBind();
