我在我的内容占位符中使用了这个量规。

MyControl.ascx:
<link rel="stylesheet" href="Scripts/jgauge.css" type="text/css" />
<script type="text/javascript" src="Scripts/jquery-1.8.0.js"></script>
<script language="javascript" type="text/javascript" src="Scripts/jgauge-0.3.0.a3.js"></script>
<script language="javascript" type="text/javascript" src="Scripts/jQueryRotate.2.2.js"></script>
<script language="javascript" type="text/javascript" src="Scripts/excanvas.min.js"></script>
<div id="<%=this.ClientID%>_ctl" class="jgauge" ></div>
<script type="text/javascript">
$(document).ready(function () {
var isPostBack = <%= Page.IsPostBack ? "true" : "false" %>;
if(isPostBack == "true")
{
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
prm.add_endRequest(onEndRequest);
}
else{
var <%=this.ClientID%>_ctl;
<%=this.ClientID%>_ctl = new jGauge();
<%=this.ClientID%>_ctl.id = '<%=this.ClientID%>_ctl';
<%=this.ClientID%>_ctl.init();
}
});
function EndRequestHandler(sender, args){
var <%=this.ClientID%>_ctl;
<%=this.ClientID%>_ctl = new jGauge();
<%=this.ClientID%>_ctl.id = '<%=this.ClientID%>_ctl';
<%=this.ClientID%>_ctl.init();
}
</script>
在 MyPage.aspx 中:(包含动态创建的具有多个此类控件的表。将生成的表放在占位符上)
<asp:UpdatePanel ID="up1" runat="server">
<ContentTemplate>
<asp:PlaceHolder id="phMain" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="myBtn" />
</Triggers>
</asp:UpdatePanel>
<asp:Button ID="myBtn" runat="server" Text="Refresh" />
我在母版页上有脚本管理器:
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>
但是在异步回发(点击'myBtn')之后,仪表消失了。请帮忙。试图解决它,因为这几天。
