This happens because your <code>Button</code> gains focus. It is possible to remove it but that means giving the focus to something else when your button's focus <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.control.enter.aspx" rel="nofollow">Enter event</a> is triggered.

<pre><code>private void button1_Enter(object sender, EventArgs e)
{
 // give focus to something else
}
</code></pre>

The problem with that is that you lose the ability to use the keyboard in order to select the button (using tab).

Moreover, a more correct approach would be to give focus to the last control that had focus instead of passing it fixed one.

have you tried to remove the focus from the button.

just call <code>Focus();</code> when the button is clicked.

Look for button border settings. 

I do not get this border, if I set the <code>BorderSize</code> to <code>0</code> in the <code>FlatAppearance</code> section

From <a href="https://stackoverflow.com/questions/9966462/remove-button-border-on-tab-c-sharp-winforms">Remove button border on tab c# winforms</a>

blocks|key|1028292|text|这里唯一不需要修改(将焦点移到另一个控件)就可以工作的答案是Wongsathon+Tuntanakan的答案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1028293|我参考了他的回答，作为额外的内容，我已经将他的代码转换为VB：|1028294|Public+Class+YourButtonClass

The only answer here that really works without having to hack (moving focus to another control) is Wongsathon Tuntanakan's answer.
I refer to his answer and, as a bit of extra, I've converted his code to VB:
<pre><code>Public Class YourButtonClass
 Inherits System.Windows.Forms.Button

 Protected Overrides ReadOnly Property ShowFocusCues As Boolean
 Get
 Return False
 End Get
 End Property
End Class
</code></pre>

How do you remove the dotted line that appears on buttons when they are selected (either via tab or by clicking them)?

This question is for <code>winforms</code> - any help is appreciated.

Edit: I apologize for the duplicate question. I did search for an answer, but I did not know this issue was due to the 'focus' of the button. As I result I was not finding the appropriate answers.

如何在按钮被选中时删除出现在按钮上的虚线(通过选项卡或通过单击按钮)？这个问题是给winforms的--任何帮助都很感谢。​​编辑:我为重复的问题道歉。我确实搜索了答案，但我不知道这个问题是由于按钮的“焦点”造成的。因此，我没有找到合适的答案。
