光标聚焦在 WPF/C# 中的文本框上 [英] Cursor Focus on Textbox in WPF/C#

问题描述

我目前正在创建屏幕键盘.我正在使用 routedcommands 处理按钮单击.问题是当我单击键盘面板中的按钮时，焦点会转移到按钮而不是文本框上.该要求规定光标应始终出现在文本框中，以指示将插入下一个字符的位置.有没有一种方法可以让我在单击按钮时将注意力集中在文本框上.

I am currently in the process of creating a Onscreen keyboard. I am handling the button click using routedcommands. The issue is that when i click on the button in keyboard panel the focus shifts to the button rather than on the Textbox. The requirement states that a cursor should always appear in the text box to indicate the position where the next character will be inserted. Is there a way i can keep focus on the textbox while button is clicked.
