TabControl (Silverlight 4) 中的验证摘要 [英] Validation Summary in TabControl (Silverlight 4)

问题描述

大家.这是我的问题.我在我的项目中使用 MVVM 模式，我有一个 UserControl，它上面有一个 TabControl.TabItem 对其进行了验证.

everyone. Here is my question. I'm using MVVM pattern in my project and i have a UserControl, which has a TabControl on it. TabItems have validations on them.

主页看起来像这样:

<UserControl>
    <DataInput:ValidationSummary x:Name="ValidationSummary"/>
    <Grid x:Name="LayoutRoot">
        <DataInput:ValidationSummary />
        <TabControl x:Name="TabControl">
            <TabItem>
                <MyUserControl1 DataContext="{Binding}" />
            </TabItem>
            <TabItem>
                <MyUserControl2 DataContext="{Binding}" />
            </TabItem>
            <TabItem>
                <MyUserControl2 DataContext="{Binding}" />
            </TabItem>
        </TabControl>
    </Grid>
</UserControl>

这是 TabItems 的示例代码:

And here is a sample code for TabItems:

<UserControl>
   <Grid>
     <Text:ExtendedTextBox Text="{Binding Name, Mode=TwoWay, ValidatesOnExceptions=true, NotifyOnValidationError=true}" />
     <Data:DataGrid SelectedItem="{Binding SelectedValue, Mode=TwoWay, ValidatesOnExceptions=true, NotifyOnValidationError=true}"/>
   </Grid>
</UserControl>

ValidationSummary 的目标设置为 LayoutRoot.但实际上，它只显示可见(当前打开)TabItem 的错误.我需要显示所有选项卡中的所有错误.我怎样才能做到这一点?

Target for ValidationSummary is set to LayoutRoot. But actually, it's showing only errors for visible(currently opened) TabItem. And i need to show all the errors from all tabs. How can i achieve this?
