当设置PopupDragHandleControlID属性时,我在将ModalPopupExtender定位在屏幕中心时遇到问题(没有此属性,它可以正常工作).
ModalPopupExtender未位于屏幕中央.我认为导致问题的原因是页面的CSS布局导致当我禁用它时,弹出窗口位于屏幕中央(我不明白为什么页面的css仅在设置了PopupDragHandleControlID属性时影响ModalPopupExtender)

模态弹出面板被赋予绝对位置.所以它需要在一个具有非静态位置的元素内部.在这种情况下,我希望它以页面为中心,所以我把它放在一个元素(在这种情况下是一个UpdatePanel,但它不管是什么类型的元素)里面有一个内联样式的位置:fixed ; left:0; top:0.
<asp:UpdatePanel ID="updProductPopup" runat="server" style="position:fixed;left:0;top:0;">
<contenttemplate>
<act:ModalPopupExtender ID="mpeProduct" runat="server" BackgroundCssClass="modalPopupBackground" BehaviorID="behaviourModalPopup" OkControlID="btnMpClose" PopupControlID="pnlModalPopup" PopupDragHandleControlID="pnlMpHandle" TargetControlID="btnMpHidden">
</act:ModalPopupExtender>
<!-- pnlModalPopup MUST have inline style display:none -->
<asp:Panel ID="pnlModalPopup" runat="server" CssClass="modalPopup" style="display:none;">
<asp:Panel runat="server" ID="pnlMpHandle" CssClass="modalPopupDragHandle">
Panel Header
</asp:Panel>
<asp:Panel runat="server" ID="pnlMpContent">Here's my content</asp:Panel>
<p class="modalPopupClose">
<a id="btnMpClose" href="#" class="custom-button">Close</a>
</p>
</asp:Panel>
<asp:Button ID="btnMpHidden" runat="server" Text="Button" CssClass="modalPopupHiddenButton" />
</contenttemplate>
我知道原来的问题很老了,但我花了很多时间寻找这个问题的答案而没有找到它,而且这个问题在Google上得到了很高的评价,所以希望这会为别人节省一些时间.

希望这可以通过两种方式来实现。
CSS：
.hcenter{margin:0 auto; width:200;} /* I have given a sample width you give the width of your popup */
代码 ：
<asp:Panel ID="pnlUploader" runat="server" CssClass="hcenter" style="display: none;">
<cc1:ModalPopupExtender ID="mdlPopup1" runat="server" TargetControlID="btnShowPopup"
PopupControlID="pnlUploader" CancelControlID="btnCancel"
BackgroundCssClass="modalBackground"
PopupDragHandleControlID="pnlUploader"
RepositionMode="RepositionOnWindowResize" />
