我定义了一个名为UserControl
的用户控件:
<UserControl x:Class="Speaker.View.Controls.Prompt"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:conv="clr-namespace:Speaker.View.Converters"
mc:Ignorable="d" Height="Auto" Width="300" x:Name="PromptBox">
<UserControl.Resources>
<conv:VisibilityConverter x:Key="VConverter" />
</UserControl.Resources>
<Border Background="White" Padding="10" BorderThickness="1"
BorderBrush="Gray" CornerRadius="10" Height="80"
Visibility="{Binding Path=Show, ElementName=PromptBox,
Converter={StaticResource VConverter}}"
UseLayoutRounding="True">
<Border.Effect>
<DropShadowEffect BlurRadius="20" RenderingBias="Quality" />
</Border.Effect>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="20" />
<RowDefinition Height="10" />
<RowDefinition Height="20" />
</Grid.RowDefinitions>
<TextBox x:Name="InputText" Width="Auto" Height="20"
Text="{Binding Path=InfoText, ElementName=PromptBox, Mode=OneWay}"
Grid.Row="0" BorderThickness="0" Foreground="#FF8D8D8D"
GotFocus="InputText_GotFocus" LostFocus="InputText_LostFocus" />
<Separator Grid.Row="1" />
<Button Content="{Binding Path=ButtonText, ElementName=PromptBox}" Grid.Row="2"
Width="100" Command="{Binding Path=OkCommand, ElementName=PromptBox}" />
</Grid>
</Border>
我想要做的是:
当用户点击按钮时,我想运行一些代码(显然 :)) - 这个控件将在其他控件/窗口中使用,并且我想运行的代码将根据场景而异。因此,如何将此按钮的
Command
属性与某个自定义命令绑定?示例用法:<ctrls:Prompt Show="{Binding ShouldLogIn}" ButtonText="{Binding LogInText}"
InfoText="{Binding LogInInfo}" OkCommand="what goes here???" Grid.Row="0" Grid.ZIndex="2" />
此外 - 我遵循MVVM模式,使用MVVMLight框架,因此我希望解决方案也遵循该模式。
所以问题是 - 如何从提示控件之外绑定到Button.Command?
