Mahapps 中的自定义弹出验证消息

Custom Popup validation message in Mahapps

我正在使用 Mahapps 创建一个 WPF 应用程序,我试图在输入错误值时更改弹出消息(如下图所示) 我想改变 "Value 'e' could not be converted."

我不太了解 Mahapps.Metro 覆盖 Metro Window 风格 似乎足够了。

比如这道题之一

<Style x:Key="newDialogStyle" BasedOn="{StaticResource MetroDialogStyle}" TargetType="{x:Type Dialogs:BaseMetroDialog}">
     <!-- ur design of Control Template -->
</Style>

<Dialogs:CustomDialog Style="{StaticResource newDialogStyle}" Title="Custom Dialog which is awaitable">
    <StackPanel>
        <TextBlock  Height="30" 
                    Text="This dialog allows arbitrary content. You have to close it yourself by clicking the close button below."
                    TextWrapping="Wrap"
                    Foreground="{DynamicResource AccentColorBrush}" />
        <Button Content="Close Me!"/>
    </StackPanel>
</Dialogs:CustomDialog>
