我有这样的用户控件:
<UserControl x:Class="MySample.customtextbox"
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"
mc:Ignorable="d"
d:DesignHeight="20" d:DesignWidth="300">
<Grid>
<TextBox x:Name="Ytextbox" Background="Yellow"/>
</Grid>
我在窗口中使用此控件并设置Tab键顺序...但是当我的窗口加载时,Tab键顺序无法正常工作! 我的窗口代码:
<Window xmlns:my="clr-namespace:MySample" x:Class="MySample.window"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="window" Height="300" Width="600">
<Grid>
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<my:customtextbox Grid.Column="1" KeyboardNavigation.TabIndex="0" InfoText="{Binding msg}" Height="20"/>
<TextBox Grid.Column="3" KeyboardNavigation.TabIndex="1" Text="{Binding msg}" Height="20" Background="Gold"></TextBox>
<my:customtextbox Grid.Row="1" Grid.Column="1" KeyboardNavigation.TabIndex="2" InfoText="{Binding msg}" Height="20"/>
<TextBox Grid.Column="3" Grid.Row="1" Text="{Binding msg}" Height="20" KeyboardNavigation.TabIndex="3" Background="Gold"></TextBox>
</Grid>

默认情况下,WPF会在同一选项卡级别读取UserControl内部和外部的所有控件。由于UserControl中的控件没有指定TabIndex,因此它们会在第一个制表符循环后标记为最后一个。
我通常使用的解决方法是在我的IsTabStop="False"
上设置UserControl
(以防止Tab键到UserControl本身),然后在UserControl
内使用TemplateBinding
绑定到内部控件TabIndex
到UserControl的TabIndex
<TextBox x:Name="Ytextbox" Background="Yellow"
TabIndex="{Binding Path=TabIndex,
RelativeSource={RelativeSource AncestorType={x:Type local:customtextbox}}}"/>
和
<my:customtextbox IsTabStop="False" KeyboardNavigation.TabIndex="0"
Grid.Column="1" InfoText="{Binding msg}" Height="20"/>
