推荐答案

将模型弹出更新面板，并使用触发器进行下拉选择的索引更改事件。会解决你的问题，







例子

Put your model pop in Update panel and use Trigger for the drop down selected index change event. will solve your problem,



Example

<asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <asp:UpdatePanel ID="UpdatePanel2" runat="server" CssClass="pnlAlign">
        <ContentTemplate>

 <asp:Button runat="server" ID="btnShowModalPopup" Style="display: none" />
                    <ajax:ModalPopupExtender ID="mpopRejectAndRework" runat="server" TargetControlID="btnShowModalPopup"

                        PopupControlID="divPopUp" BackgroundCssClass="modalBackground" DropShadow="true"

</ContentTemplate>

 <asp:DropDownList ID="ddlStatus" runat="server" Width="200px" AutoPostBack="True" CssClass="input"

                                        OnSelectedIndexChanged="ddlStatus_SelectedIndexChanged">
