如何设置对NumericUpDown控件的关注？ [英] How to set focus on NumericUpDown control?

问题描述

我试图将重点放在WPF扩展工具包中的NumericUpDown元素上。

我遵循XAML

I am trying to set focus on NumericUpDown element from WPFs extended toolkit.
I heve following XAML

<Window ... 
    xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended"
<Grid>
    <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center" Orientation="Horizontal" FocusManager.IsFocusScope="True">
        <extToolkit:NumericUpDown HorizontalAlignment="Left" VerticalAlignment="Top" x:Name="ItemsCount" Value="1"/>
        <TextBlock Text="XXX" Margin='10,0,0,0'/>
    </StackPanel>        
</Grid>
</Window>

我叫 Keyboard.Focus（ItemsCount）和 ItemsCount.Focus（）分别来自构造函数和 Loaded 事件，均未成功。

控制当我按Tab时会得到焦点，但在我的情况下这是不可接受的。

我也没有在Google上找到问题。

有什么方法可以聚焦NumericUpDown吗？

I called Keyboard.Focus(ItemsCount) and ItemsCount.Focus() from constructor and from Loaded event with no success.
Control is getting focus when I press Tab, but in my case it is not acceptable.
I didn't found enything on google as well.
Is there any way to focus NumericUpDown?

PS

调用Focus（）适用于 TextBox ，因此它必须是控件特定的问题。

P.S.
Calling Focus() works for TextBox so it's must be control specific issue.

推荐答案

也许未设置为可聚焦，是否检查了可聚焦？

Maybe it is not set to be focusable, have you checked the value of Focusable?
