本文示例源代码或素材下载

在Silverlight3中对数据进行校验不再像Silverlight2中那样麻烦了,下面就简要演示一下。

首先,我们创建一个Silverlight3应用,名为:"ValidateSample"

然后将下面的xaml代码复制到"MainPage.xaml"中: 

<Grid x:Name="LayoutRoot" Background="AliceBlue">
        <Grid.RowDefinitions>
            <RowDefinition Height="50" />
            <RowDefinition Height="50" />
            <RowDefinition Height="150" />
            <RowDefinition Height="50" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="50"></ColumnDefinition>
            <ColumnDefinition Width="300"></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <TextBlock Text="地址:" Grid.Row="0" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Right"/>
        <TextBox Margin="5" Name="Address" VerticalAlignment="Center" Width="192" Grid.Row="0" Grid.Column="1"
                Text="{Binding Address,Mode=TwoWay,ValidatesOnExceptions=True,NotifyOnValidationError=True}"/>
        <TextBlock Text="标题:" Grid.Row="1" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Right"/>
        <StackPanel  Grid.Row="1" Grid.Column="1" Orientation="Horizontal" HorizontalAlignment="Right">
           <TextBox Margin="5"  Name="Title" VerticalAlignment="Center" Grid.Row="1" Grid.Column="1" Width="160"
                Text="{Binding Title,Mode=TwoWay,ValidatesOnExceptions=True,NotifyOnValidationError=True}" />
            <ComboBox Name="EmailFormat" Width="80" Height="20" SelectedIndex="{Binding Format,Mode=TwoWay,ValidatesOnExceptions=True,NotifyOnValidationError=True}">
                <ComboBoxItem Content="邮件格式"></ComboBoxItem>
                <ComboBoxItem Content="Html"></ComboBoxItem>
                <ComboBoxItem Content="Text"></ComboBoxItem>
            </ComboBox>           
        </StackPanel>

        <TextBlock Text="内容:" Grid.Row="2" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Right"/>
        <TextBox Margin="5" Name="Body" Grid.Row="2" Grid.Column="1"  Width="230" Height="130"
                Text="{Binding Body,Mode=TwoWay,ValidatesOnExceptions=True,NotifyOnValidationError=True}" />

        <Button Grid.Row="3" Grid.Column="1" Content=" 提 交 "  Width="100" Height="30" FontSize="16"/>
        <!--Click="OnSubmit"-->
</Grid>
