Silverlight不；t调用OnLoad参数

本文关键字：OnLoad 参数 调用 Silverlight | 更新日期: 2023-09-27 17:59:01

我已经设置了Silverlight ASPX页面，如下所示：

<%@ Page Language="C#" MasterPageFile="~/ASPResources/MasterPage.master" AutoEventWireup="true"
CodeBehind="SilverlightPage.aspx.cs" Inherits="Adapt.Presentation.AssetInventory.SilverlightPage"
Title="Xivic" %>
<%@ MasterType VirtualPath="~/ASPResources/MasterPage.master" %>
<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"
TagPrefix="asp" %>
<asp:Content ID="Content2" ContentPlaceHolderID="mainContent" runat="server">
<script type="text/javascript" id="silverlightport">
    var silverlightControl = null;
    function pluginLoaded(sender, args)
    {
        silverlightControl = sender.getHost();
    }
    function externalCommand(data)
    {
        if (silverlightControl != null)
        {
            silverlightControl.Content.JSR.ExternalCommand(data);
        }
        else
        {
            alert("Couldn't get silverlight host object in SilverlightPage.aspx");
        }
    }
</script>
<asp:Silverlight ID="SilverlightLaunchPage" EnableGPUAcceleration="true" runat="server"
    Source="~/ClientBin/Xivic.xap" Width="100%" Height="100%" InitParameters="onLoad=pluginLoaded" />

Silverlight启动并且不能调用pluginLoaded函数，因为当我调用externalCommand功能时，未设置silverlightControl变量。因此，要么是我的Silverlight页面没有加载（我很确定它已经加载了），要么我的onLoad事件一定没有正确挂接（这更有可能是因为我对ASP几乎一无所知）。

有人能告诉我我在这里做错了什么吗？

Silverlight不；t调用OnLoad参数

这里是Silverlight 5控件的一个示例。我将其调整为您在示例中的内容

<head runat="server">
    <script type="text/javascript" src="..'Scripts'Silverlight.js"></script>
    <script type="text/javascript">
        function onSilverlightError(sender, args) {
            var appSource = "";
            if (sender != null && sender != 0) {
                appSource = sender.getHost().Source;
            }
            var errorType = args.ErrorType;
            var iErrorCode = args.ErrorCode;
            if (errorType == "ImageError" || errorType == "MediaError") {
                return;
            }
            var errMsg = "Unhandled Error in Silverlight Application " + appSource + "'n";
            errMsg += "Code: " + iErrorCode + "    'n";
            errMsg += "Category: " + errorType + "       'n";
            errMsg += "Message: " + args.ErrorMessage + "     'n";
            if (errorType == "ParserError") {
                errMsg += "File: " + args.xamlFile + "     'n";
                errMsg += "Line: " + args.lineNumber + "     'n";
                errMsg += "Position: " + args.charPosition + "     'n";
            }
            else if (errorType == "RuntimeError") {
                if (args.lineNumber != 0) {
                    errMsg += "Line: " + args.lineNumber + "     'n";
                    errMsg += "Position: " + args.charPosition + "     'n";
                }
                errMsg += "MethodName: " + args.methodName + "     'n";
            }
            throw new Error(errMsg);
        }

            {
                silverlightControl.Content.JSR.ExternalCommand(data);
            }
            else
            {
