silverlight 不能输入中文问题

<param name="Windowless" value="true" />
将调用silverlight页面的这句删除掉应该就能解决问题了

1.将<param name="Windowless" value="true" />以上代码注释（删除）操作，虽然可以输入中文，但是silverlight嵌套html将会报错？想要解决silverlight嵌套html问题、silverlight无法输入中文问题，只能是换一种实现方法。具体操作如下
1.自定义用户控件HtmlHost.cs

        private static void SourceHtmlChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        {
            ((HtmlHost)sender).x8c7c45ccab715fbf();
        }

        public HtmlDocument Document
        {
            get
            {
                return this._document;
            }
            private set
            {
                if (value != this._document)
                {
                    this._document = value;
                    if (this._document == null)
                    {
                        return;
                    }
                    this.OnDocumentReady(EventArgs.Empty);
                }
            }
        }

        public HtmlWindow Window
        {
            get
            {
                HtmlWindow property = this._iframe.GetProperty("contentWindow") as HtmlWindow;
                return property;
            }
        }

        public string SourceHtml
        {
            get
            {
                return (string)base.GetValue(SourceHtmlProperty);
            }
            set
            {
                base.SetValue(SourceHtmlProperty, value);
            }
        }

        public Uri SourceUri
        {
            get
            {
                return (Uri)base.GetValue(SourceUriProperty);
            }
            set
            {
                base.SetValue(SourceUriProperty, value);
            }
        }

        private HtmlElement IFrame
        {
            get
            {
                if (this._iframe != null)
                {
                    return this._iframe;
                }
                if (HtmlPage.IsEnabled)
                {
                    this._iframe = HtmlPage.Document.CreateElement("iframe");

                    this._iframe.SetStyleAttribute("position", "absolute");
                    this._iframe.SetStyleAttribute("width", "100%");
                    this._iframe.SetStyleAttribute("height", "100%");
                    this._iframe.SetStyleAttribute("border", "0px");
                    this._iframe.SetAttribute("border", "0");
                    this._iframe.SetAttribute("frameBorder", "0");
                    this._iframe.AttachEvent("onload", new EventHandler(this.IFrame_Loaded));
                    HtmlPage.Document.Body.AppendChild(this._iframe);
                }
                return this._iframe;
            }
        }
    }
}

2.将自定义用户控件引用到页面中MainPage.xaml

<UserControl x:Class="HtmlInSilverlight.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    xmlns:Html="clr-namespace:HtmlInSilverlight" 
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="25"></RowDefinition>
            <RowDefinition></RowDefinition>
            </Grid.RowDefinitions>
            <TextBox Text="" Grid.Row="0"></TextBox>
        <Html:HtmlHost Grid.Row="1" x:Name="htmlControl" SourceUri="http://hao.360.cn"></Html:HtmlHost>

    </Grid>
</UserControl>

这样就ok了。

注意：将.aspx中<param name="Windowless" value="true" />这段话注释或者删除。

 3.此做法可能还会出现异常

4.最终做法

 Label_0153:
            this._div.SetStyleAttribute("visibility", "visible");
            this._div.SetStyleAttribute("display", "inline");
            this._div.SetStyleAttribute("background", "White");
            if ((((uint)num) & 0) != 0)
            {
                goto Label_02A0;
            }

将这段代码替换HtmlHost.cs中的代码，与HtmlHost.cs类库不同的是 多加了

this._div.SetStyleAttribute("background", "White"); 
具体什么原因，我也不清楚
