WinForm questions about AcceptButton and Cancelebutton

1.Form.acceptbutton Property : Gets or sets the button on the form pressed by the user when the ENTER key is pressed, the button assigned to this property must be on the current form or in the container on the current table . IButtonControl (that is, only the button can use it.)

Private void Form1_Load (object sender, EventArgs e) {This    . button2;     This this. Button3;}

See MSDN

This nature allows you to specify the presets that occur when the user presses the ENTER key in the application. The button assigned to this IButtonControl must be on the current table or in the container on the current table .

You can use this to allow users to simply press ENTER when they're done, instead of clicking on the button with a mouse button to quickly navigate through the simple list of keys.

If the control currently selected on the form suspend the key and handles it, you cannot activate the Accept button. For example, when you select it to insert new line Character into the control, the multiline text block control allows you to press ENTER.

Imagine if the user after the TextBox to fill in the information, without the mouse, press Enter to perform the next move, is not somewhat convenient.

2.Form.cancelbutton : Gets or set the button control that the user presses when the ESC key is pressed. 

3.Form.acceptbutton : Is the button event that you want to perform after you press ENTER, and I actually find that the focal point of this thing on the Form is used on the non- button! with the focus method , it's a lot more bouncy.

4.Form.cancelbutton : Not controlled by the focus of the impact, no matter where you press ESC can work very normal. 

5. The example is as follows:

Static intJ=1;Static intI=1;Static intK = 1;Private voidForm1_Load (Objectsender, EventArgs e) { This. AcceptButton = This. button1; This. Textbox1.focus (); This. Textbox1.select (); This. CancelButton = This. Button3;}Private voidButton1_Click (Objectsender, EventArgs e) {TextBox1.Text ="pressed the button1:"+j.tostring () +"Times"; This. Textbox2.focus ();//this.textbox2.select ();j + +; This. AcceptButton = This. button2;}Private voidButton2_Click (Objectsender, EventArgs e) {TextBox2.Text ="pressed the button2:"+i.tostring () +"Times"; This. Textbox1.focus ();//this.textbox1.select ();i++; This. AcceptButton = This. Button1;}Private voidButton3_Click (Objectsender, EventArgs e) {textbox3.text ="pressed ESC:"+ k.tostring () +"Times"; k++;}
