Question

下拉列表的HTML代码是

 <div style="float: left; width: 100%; margin-top: 5px;">
        <div style="float: left; width: 42%;">
            <span class="Red_Bold_70">* </span>
            <asp:Label ID="lblStateTitle" runat="Server" Text="State/Province: " CssClass="NoColor_Bold_70"></asp:Label>
        </div>
        <div style="float: left; width: 54%; padding-left: 4px;">
            <asp:DropDownList ID="ddlState" runat="server" CssClass="NoColor__70">
            </asp:DropDownList>
            <asp:RequiredFieldValidator ID="rfvStateDDL" runat="server" ErrorMessage="* State is required" ControlToValidate="ddlState" CssClass="Red__70" Display="Dynamic" InitialValue="0"></asp:RequiredFieldValidator>
            <asp:TextBox ID="txtState" runat="server" CssClass="NoColor__70" Width="50%" Text=""></asp:TextBox>
            <asp:RequiredFieldValidator ID="rfvStateTextBox" runat="server" ErrorMessage="* State is required" ControlToValidate="txtState" CssClass="Red__70" Display="Dynamic" InitialValue="0"></asp:RequiredFieldValidator>
        </div>
    </div>

代码背后：

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
   If Not Page.IsPostBack Then

        PopulateCountryDDL()
        PopulateStateDDL()
   end if 
end sub

populateStateDDL从数据源中恢复状态。

 Protected Sub ddlState_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ddlState.SelectedIndexChanged


        selectedState = ddlState.SelectedValue.ToString()

End Sub

当我检查ddlstate所选项目的值时，我看到了一个随机值而不是select.owever，但它适用于少数几个选项，并且经常不是很少。你可以在这里建议可能是什么问题？

下拉列表显示随机选择，而不是在提交时选择用户
