前台代码：

<div style="position: relative;">            <span style="margin-left: 132px; width: 18px; overflow: hidden;">                <asp:DropDownList ID="DropDownList1" runat="server" Style="width: 150px; margin-left: -132px"                    AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">                    <asp:ListItem>1</asp:ListItem>                    <asp:ListItem>2</asp:ListItem>                    <asp:ListItem>3</asp:ListItem>                </asp:DropDownList>            </span>            <asp:TextBox ID="TextBox1" runat="server" Style="width: 126px; position: absolute;                left: 0px;" AutoPostBack="True" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>        </div>

后台代码：

    //具体可以根据自己使用时扩展    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)    {        TextBox1.Text = DropDownList1.SelectedItem.Text;    }    protected void TextBox1_TextChanged(object sender, EventArgs e)    {        DropDownList1.SelectedValue = TextBox1.Text;    }
