How to implement key event for button click event

Question

Hi everybody!

I'm writing a virtual keyboard, and i have a problem.

As we know when press a key on real keyboard, control which focused will receive key event (defined by .Net)

for example:

you focus in a Multi line textbox, when you press key Enter. textbox will add 1 line and show cursor at that line.

. I think that textbox will receive Enter 's key code , after that textbox will perform 1 action with this Enter keycode.

so now i want to know that how to implement key event from buttton click event for a control.

Please help me! Thanks!!!

Kind regards.

Here is Code for it . I have Show Code For Two Buttons but you can make it for more buttons too.. private void Form1_Load( object sender, EventArgs e) { this .KeyPreview = true ; } private void Form1_KeyDown( object sender, KeyEventArgs e) { if (e.KeyCode == Keys .A) { button1.PerformClick(); } else if (e.KeyCode == Keys .B) { button2.PerformClick(); } } private void button1_Click( object sender, EventArgs e) { MessageBox .Show( "Button A" ); } private void button2_Click( object sender, EventArgs e) { MessageBox .Show( "Button B" ); }

Ok friend, if you want to send key to any control then you can do it with SendKeys.Send("A"); if you want to send Enter Key then SendKeys.Send(" {Enter} "); that will send "A" to control ..

you don't understand. Have you ever wonder that why do you press number 1 on the real keyboard, at that time textbox input value is 1 ? i think that every control have method to handle that event. so i want to know that method to handle control so that i don't need writing code to handle data

private void btnEnter_Click( object sender, EventArgs e) { textBox1.Text += "
" ; textBox1.Text += "" ; textBox1.Focus(); textBox1.SelectionStart = textBox1.Text.Length; } private void btnA_Click( object sender, EventArgs e) { textBox1.Text += "a" ; textBox1.Focus(); textBox1.SelectionStart = textBox1.Text.Length; } private void btnB_Click( object sender, EventArgs e) { textBox1.Text += "b" ; textBox1.Focus(); textBox1.SelectionStart = textBox1.Text.Length; }

no, i don't want to writing code handle, i want to send keycode for textbox, and textbox will perform a action with this keycode. Ex: you focus in a Multi line textbox, when you press key Enter. textbox will add 1 line and show cursor at that line. .Textbox will receive Enter 's key code , after that textbox will perform 1 action with this Enter keycode.
