模态弹出扩展器没有显示

Question

我在页面上有两个模态弹出扩展器

<cc1:ModalPopupExtender ID="ModalPopupConfirm" runat="server"
                        TargetControlID="Button4"
                        PopupControlID="pnlPopup"
                        BackgroundCssClass="ModalPoopup"
                        BehaviorID="popup" />

<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server"
                        TargetControlID="anchorbtn"
                        X="200" RepositionMode="None"
                        PopupDragHandleControlID="EmptyPanel"
                        PopupControlID="pnlSelfOrLetOut"
                        BackgroundCssClass="ModalPoopup"
                        BehaviorID="popupSL" />

我正在调用c＃中的第一个模态弹出扩展器

ModalPopupExtender1.Show();

模态弹出窗口没有显示。

请帮帮我。
