Question

是否可以将自动对焦设置为我的xaml文件中的文本框？

<Window x:Class="WpfApplication1.Views.Test1"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            Height="100"
            Width="210"
            WindowStartupLocation="CenterOwner"
            ShowInTaskbar="False"
            Background="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"
            ResizeMode="CanResizeWithGrip">
    <TextBox HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Visible" TextWrapping="Wrap" AcceptsReturn="True" Text="{Binding Path=Text, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</Window>

Answer 1

<TextBox FocusManager.FocusedElement="{Binding RelativeSource={RelativeSource Self}}" />

Answer 2

是的，您可以使用 FocusManager.FocusedElement 附加属性。

FocusManager.FocusedElement="{Binding ElementName=textBox1}"

Answer 3

尝试这样的事情

<Window x:Class="WpfApplication18.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="500" Width="525" FocusManager.FocusedElement="textcontrol">
    <Grid>
       <TextBox Name="textcontrol" />
    </Grid>
</Window>

Answer 4

我认为绑定是一种矫枉过正，参考更轻量级：

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        FocusManager.FocusedElement="{x:Reference textBox1}">
    <StackPanel>
        <TextBox x:Name="textBox1" />
    </StackPanel>
</Window>

Answer 5

我通常用C＃解决这个问题

textBox1.Focus();

我认为这是如何做到这一点的最好方法。

如何仅在xaml中设置自动对焦？
