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

2.将自定义用户控件引用到页面中MainPage.xaml
1 <UserControl x:Class="HtmlInSilverlight.MainPage" 2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 4 xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 5 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 6 mc:Ignorable="d" 7 xmlns:Html="clr-namespace:HtmlInSilverlight" 8 d:DesignHeight="300" d:DesignWidth="400"> 9 10 <Grid x:Name="LayoutRoot" Background="White"> 11 <Grid.RowDefinitions> 12 <RowDefinition Height="25"></RowDefinition> 13 <RowDefinition></RowDefinition> 14 </Grid.RowDefinitions> 15 <TextBox Text="" Grid.Row="0"></TextBox> 16 <Html:HtmlHost Grid.Row="1" x:Name="htmlControl" SourceUri="http://hao.360.cn"></Html:HtmlHost> 17 18 </Grid> 19 </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
