RT,SL版本4.0.50917
用VS2010建一个SilverlightApplication
MainPage代码如下<UserControl x:Class="SilverlightApplication4.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/up-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">    <Grid x:Name="LayoutRoot" Background="White">
        <Button Height="23" HorizontalAlignment="Left" Margin="197,142,0,0" Name="button1" VerticalAlignment="Top" Width="75" IsEnabled="False">
            <Button.Content>
                dfdfafda
            </Button.Content>
        </Button>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="197,211,0,0" Name="button2" VerticalAlignment="Top" Width="75" />
    </Grid>
</UserControl>编译会报错,求高手,问SL4里是不是button.content的属性不能这么写?
