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

                 }
                 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="" d:DesignWidth="">

     <Grid x:Name="LayoutRoot" Background="White">
         <Grid.RowDefinitions>
             <RowDefinition Height=""></RowDefinition>
             <RowDefinition></RowDefinition>
             </Grid.RowDefinitions>
             <TextBox Text="" Grid.Row=""></TextBox>
         <Html:HtmlHost Grid.Row="" 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) & ) != )
            {
                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
