Iam stuck with this issue for quite some time. I have a button control in a vb.net winform. I want to set focus on this button for which i have used the btnSave.Select(), but this function sets the focus on the button without displaying the dashed rectangle around the button. How can i create dashed rectangle around a button control programatically? Please help. This is really urgent!


Thanks & Regards,

尝试使用btnSave.Focus()代替btnSave.Select()

尝试btnSave.Focus().

它不是Select，它是Focus.

例如，在自定义控件类中自定义绘制Button时，只需要绘制一个虚线矩形即可.

您可以使用的一种课程是System.Windows.Forms.ButtonRenderer.此类是已渲染的，它只是使用Graphics实例进行绘制，但是它一次渲染了整个按钮，而不是单独的元素.

如果要使用单独的元素，请使用System.Windows.Forms.ControlPaint.您可能要对虚线矩形使用System.Windows.Forms.ControlPaint.DrawGrid.还有许多其他有用的方法.

It''s not Select, it''s Focus.

You only need to draw a dashed rectangle if you custom-draw your Button, for example, in your custom control class.

One class you can use is System.Windows.Forms.ButtonRenderer. This class is the rendered, it just draw using the Graphics instance, but it renders the whole button at once, not its separate elements.

If you want a separate elements, use System.Windows.Forms.ControlPaint. You may want to use System.Windows.Forms.ControlPaint.DrawGrid for your dotted rectangle. There are many other useful methods.
