专注于文本框 [英] Keep focus on textbox

问题描述

大家好，

我正在尝试通过执行以下操作将初始焦点设置在UserControl中的某个Textbox上:

Hi all,

I am trying to set the initial focus on a certain Textbox within my UserControl, by doing the following:

<br />
<pre><br />
FocusManager.FocusedElement="{Binding ElementName=txtBarCode}"<br />
</pre><br />

A .它设置了焦点，但是光标没有闪烁?仅当我单击文本框"时，它才会开始闪烁吗?
B .其次，如何保持对文本框的关注.

提前非常感谢！
问候

A. It sets the focus, but the cursor does not flicker? Only when I click on the Textbox, does it start flickering?
B. Secondly, how can I keep the focus on the Textbox.

Many thanks in advance!
Kind regards
