onclick不起作用了，求解

C# code

//原本的代码（onclick没有问题）：<A:ButtonEx ID="btnAdvancedSearch_Up" runat="server" Text="预览结果" OnClick="btnAdvancedSearch_Click"/><A:ButtonEx ID="btnCancel_Up" runat="server" Text="取消" OnClick="btnCancel_Click"/>//修改后的代码<Anshu:ButtonEx ID="btnAdvancedSave_Up" runat="server" Text="保存检索条件到个人数据分类"/><A:ButtonEx ID="btnAdvancedSearch_Up" runat="server" Text="预览结果" OnClick="btnAdvancedSearch_Click"/><A:ButtonEx ID="btnCancel_Up" runat="server" Text="取消" OnClick="btnCancel_Click"/>//添加代码：<A:PopupPanelControl ID="FilterPopupPanel" runat="server" Width="400" Height="100" Caption="分类"><A:ButtonEx ID="btnCategoryOk" runat="server" Text="确定" CausesValidation="false" CommandName="OK" OnClientClick="if(!onSave()) return false;" OnClick="btnCategoryOk_Click"/><A:ButtonEx ID="btnCategoryCancel" runat="server" Text="取消" CausesValidation="false" CommandName="Cancel" OnClick="btnCategoryCancel_Click"/><asp:HiddenField ID="hd_IsHide" runat="server" /></A:PopupPanelControl><script type="text/javascript">        //初始化        $(document).ready(function () {            reload();               var isHide = $('<%=hd_IsHide.ClientID %>').val();            if (isHide == null ||  isHide == "hide"){                HideFilterPopupPanel();            }            else{                ShowFilterPopupPanel();            }        });        function reload() {            Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);        }        function EndRequestHandler() {            var isHide = $('<%=hd_IsHide.ClientID %>').val();            if (isHide == null  ||  isHide == "hide"){                HideFilterPopupPanel();            }            else{                ShowFilterPopupPanel();            }        }        function HideFilterPopupPanel(){           <%=FilterPopupPanel.ClientID%>.Hide();        }        function ShowFilterPopupPanel(){            <%=FilterPopupPanel.ClientID%>.Show();        }        function onSave() {            var categoryName = <%=txtCategoryName.ClientID %>.GetValue();;            options = {                type: "POST",                url: "……",                contentType: "application/json;charset=utf-8",                dataType: "json",                async: false            };            returnText = $.ajax(options).responseText;        }</script>//aspx.cs页面：onLoad方法添加：btnAdvancedSave_Up.OnClientClick = string.Format("ShowFilterPopupPanel();return false;", FilterPopupPanel.ClientID);

是不是因为弹出的这个PopupPanelControl，或者是因为我在添加的那个buttom用了Ajax？..
求解以及解决方法……

试试 是不是跟页面加载元素顺序有关

onclientclick


在不行的话，直接在后台注册一个js事件：

C# code

btndisply.Attributes.Add("onclick", "javascript:return bntAddClick();");
