问题描述
我在 C# 中有一个包含 TextBox
的表单,我将其设置为如下字符串:
I have a form containing a TextBox
in C# which I set to a string as follows:
textBox.Text = str;
表单显示时,为什么texbox中的文字会高亮/选中?
When the form is displayed, why does the text in the texbox appear highlighted/selected?
推荐答案
文本框的 TabIndex
为 0,TabStop
设置为 true.这意味着当窗体显示时,控件将获得焦点.
The text box has a TabIndex
of 0 and TabStop
set to true. This means that the control will be given focus when the form is displayed.
您可以给另一个控件 0 TabIndex
(如果有的话)并给文本框一个不同的标签索引 (>0),或者将 TabStop
设置为文本框为 false 以阻止这种情况发生.
You can either give another control the 0 TabIndex
(if there is one) and give the text box a different tab index (>0), or set TabStop
to false for the text box to stop this from happening.
