How can I trigger the default button on a form without clicking it (winforms)?

Question

I have two text boxes. one for login id and another is for password. and there is one button (submit). I need an event that takes the values of login id and password. I.e, without clicking the mouse I need to invoke this event(just by hitting 'enter' on keyboard). can anybody help me!

thanx in advance. srini.

Answer 1

Set the button to be the accept button on the form. You can do this by setting the forms "AcceptButton" property to be the button you want to trigger. This will make an enter key press trigger the button.

Answer 2

If you don't want the button to be the default you can hook both TextBoxes KeyPress events to same handler then check if Enter was pressed using KeyEventArgs.KeyCode.

Answer 3

If you need to be able to navigate the form without the mouse, you'll want to make sure your tab stops are set correctly. I would set Login Id as the first, password as the second, and your submit button as the third. Then the user can navigate easily among them. IIRC, the default behavior of buttons is to fire off the On_Click event if the Enter key is pressed while the button has focus.

Answer 4

Hi, Simon P Stevens gave you the most adequate answer.

I would just add that you also have the possibility to set a form's CancelButton on which a click event would be triggered when you press the escape ESC key.

Quick summary

Enter --> AcceptButton

Esc --> CancelButton

Answer 5

use

buttonName.PerformClick();
