wpf - 将 Visibility 枚举值作为 ConverterParameter 传递

Question

我想知道如何传递 System.Windows.Visibility Enum 作为转换器的参数:

<Bdl:BdlRoundButton Name="BtAddUser" Grid.Row="1" Grid.Column="2" Color="Orange" Image="Create" Command="{StaticResource GetSequence}" Margin="5,0,0,0"
                            Visibility="{Binding Converter={StaticResource StringNotNullToVisibilityConverter}, ConverterParameter={System.Windows.Visibility.Hidden}}"/>

Answer 1

正如 @dkozl 已经提到的，您可以使用 x:Static Markup Extension :

References any static by-value code entity that is defined in a Common Language Specification (CLS)–compliant way. The static property that is referenced can be used to provide the value of a property in XAML.

所以你的代码应该是这样的:

<Bdl:BdlRoundButton Name="BtAddUser" Grid.Row="1" Grid.Column="2" Color="Orange" 
                    Image="Create" Margin="5,0,0,0"
                    Command="{StaticResource GetSequence}" 
                    Visibility="{Binding Converter={StaticResource StringNotNullToVisibilityConverter}, ConverterParameter={x:Static Visibility.Hidden}}"/>
