我有一个非常简单的 WPF UserControl:
<UserControl x:Class="dr.SitecoreCompare.WPF.ConnectionEntry"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="connEntry"
BorderBrush="Navy" BorderThickness="1" Margin="5,0,0,5" >
<StackPanel Margin="0,10,0,0" >
<Label FontWeight="ExtraBold" Content="{Binding ElementName=connEntry, Path=Title}"></Label>
<Label Margin="0,5,0,0">Server:</Label>
<TextBox x:Name="txtServer" TabIndex="1" Text="{Binding Path=ServerName}" ></TextBox>
<Label>Database:</Label>
<TextBox x:Name="txtDatabase" TabIndex="2" Text="{Binding Path=DatabaseName}"></TextBox>
</StackPanel>
这在同一个窗口中使用了两次。现在,我可以在我的 UserControl 的两个实例上选择第一个 TextBox,但无法选择第二个(“txtDatabase”)文本框,无论是通过 Tab 还是单击。为什么是这样 ?关于创建 WPF 用户控件,我是否遗漏了什么?
编辑: DatabaseName 不是只读的,它是一个简单的属性。放置用户控件的窗口的 XAML 如下所示:
<Window x:Class="dr.SitecoreCompare.WPF.ProjectDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:c="clr-namespace:dr.SitecoreCompare.WPF"
Title="Choose project" Height="280" Width="500"
WindowStartupLocation="CenterOwner" WindowStyle="SingleBorderWindow" HorizontalAlignment="Center" ShowInTaskbar="False" ShowActivated="True" ResizeMode="NoResize" VerticalContentAlignment="Top" VerticalAlignment="Center">
<StackPanel>
<Label>Choose databases</Label>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<c:ConnectionEntry Grid.Column="0" x:Name="connMaster" Title="Master:" Padding="5" />
<c:ConnectionEntry Grid.Column="1" x:Name="connSlave" Title="Slave:" Padding="5" />
</Grid>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0,0" >
<Button x:Name="btnCancel" Click="btnCancel_Click">Cancel</Button>
<Button x:Name="btnOK" Click="btnOK_Click">OK</Button>
</StackPanel>
</StackPanel>
</Window>
