按钮是自动选择的（如何关闭它？）

Question

I have winform buttons that when you load the form, a certain button is selected. What I mean by selected, is that if "enter" is pressed, the button is pressed.

How can I change my buttons so they don't do this anymore?

Answer 1

Your tab order is set in the order in which you add controls on the form. If your first control which can be pressed/selected/edited is that button which is getting pressed, the focus will automatically be on it when form is loaded.

You can cheat by setting the focus to some other control (maybe which is not visible? !hint * hint!) to avoid the button to be selected at first.

But also make sure tht button is not the AcceptButton of the form.

Answer 2

Two concepts have been touched on by Nayan and rerun:

1) AcceptButton 2) Tab order

There is one more I would add and then try to explain how the three things relate:

3) Focus

Focus means that a child control has the "keyboard focus". When a control has focus, it receives keyboard input and can respond to it. Focus is changed either by clicking a control with the mouse, or by using the Tab key.

Tab order is the order in which controls receive focus when the Tab key is pressed. It also determains which control initially gets focus (the first one in tab order).

The AcceptButton concept is a bit of a hybred. If a form's AcceptButton property is set to a button control, that button is pressed when the user presses the Enter key while focus is on any control that does not process the enter key itself. Typically the 'Ok' button on a form is set as the AcceptButton so that the user can enter data and press Enter as a shortcut to pressing the Ok button.
