Anyway, I have modal pop up extender in usercontrol then I used my user control twice in one page.

My problem is I can't close it with esc key is click with the code above. it always null or cant find something.

Then, I tried using behaviorID but it cannot be done too.

    function pageLoad(sender, args) {
        if (!args.get_isPartialLoad()) {
            $addHandler(document, "keydown", onKeyDown);
        }
    }


    function onKeyDown(e) {
        if (e && e.keyCode == Sys.UI.Key.esc) {
            $find('bhiModalPopupExtender1').hide();
        }
    }


<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Panel1" TargetControlID="hdnModalPopup" BehaviorID="bhiModalPopupExtender1"

    CancelControlID="hdnModalPopup" BackgroundCssClass="modalBackground">
</cc1:ModalPopupExtender>Thanks for helping.

推荐答案

addHandler（document，keydown，onKeyDown ）;
}
}

函数隐藏（controlID）{
var mpe =

addHandler(document, "keydown", onKeyDown); } } function Hide(controlID) { var mpe =

find（controlID）;
mpe.hide（）;
var mpe =

find(controlID); mpe.hide(); var mpe =

find（'ModalPopupExtender1'）;
mpe.hide（）;
}
函数onKeyDown（e）{
if（e&& e.keyCode == Sys.UI.Key.esc）{
Hide（document.getElementById（ <％ = ModalPopupExtender1.ClientID ％> ））;
}
}

我仍​​然无法找到任何答案。

无论如何，我在usercontrol中有模态弹出扩展器，然后我在一个页面中使用了我的用户控件两次。

我的问题是我无法用esc键关闭它，点击上面的代码。它总是无效或无法找到某些东西。

然后，我尝试使用behaviorID，但它也无法完成。

function pageLoad（sender，args）{
if（！args.get_isPartialLoad（））{

find('ModalPopupExtender1'); mpe.hide(); } function onKeyDown(e) { if (e && e.keyCode == Sys.UI.Key.esc) { Hide(document.getElementById("<% =ModalPopupExtender1.ClientID%>")); } } </script>Close with escape key ajax ModalPopupExtender not working in two days of searching I can't still find any answer for this.
