Enter Key Press in C#

Enter key press in C#

Try this code,might work (Assuming windows form):

private void CheckEnter(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if (e.KeyChar == (char)13)
{
// Enter key pressed
}
}

Register the event like this :

this.textBox1.KeyPress += new 
System.Windows.Forms.KeyPressEventHandler(CheckEnter);

Button KeyPress Not Working for Enter Key

When a Button has focus and you press Enter or Space the Click event raises.

So to handle Enter or Space it's enough to handle Click event and put the logic you need there.

So you just need to use button1.Click += button1_Click;

private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("Clicked!");
}

If you really want to know if Enter or Space was pressed, you can hanlde PreviewKeyDown event:

private void button1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
if(e.KeyCode== Keys.Enter)
{
MessageBox.Show("Enter");
}
if (e.KeyCode == Keys.Space)
{
MessageBox.Show("Space");
}
}

Enter key pressed event handler

Either KeyDown or KeyUp.

TextBox tb = new TextBox();
tb.KeyDown += new KeyEventHandler(tb_KeyDown);

static void tb_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
//enter key is down
}
}

press Enter key instead of clicking on a button in c#

Is this WinForms? If so, you can set the AcceptButton of the form to be the button in question. Doing so will make pressing Enter behave exactly like clicking the button with the mouse, but it will only have that effect if the currently focused element isn't something else that will also capture the keypress.

Press enter in textbox to and execute button command

You could register to the KeyDown-Event of the Textbox, look if the pressed key is Enter and then execute the EventHandler of the button:

private void buttonTest_Click(object sender, EventArgs e)
{
MessageBox.Show("Hello World");
}

private void textBoxTest_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
buttonTest_Click(this, new EventArgs());
}
}

Detect Enter Key C#

This is because when you press Enter TextChanged event won't fire.

a custom event for pressing the 'Enter key' in C#

Sure, you can just add, say, an EnterPressed event and fire it when you detect that the Enter key was pressed:

public partial class UserControl1 : UserControl {
public event EventHandler EnterPressed;

public UserControl1() {
InitializeComponent();
textBox1.KeyDown += textBox1_KeyDown;
}

protected void OnEnterPressed(EventArgs e) {
var handler = this.EnterPressed;
if (handler != null) handler(this, e);
}

void textBox1_KeyDown(object sender, KeyEventArgs e) {
if (e.KeyCode == Keys.Enter) {
OnEnterPressed(EventArgs.Empty);
e.Handled = e.SuppressKeyPress = true;
}
}
}

How do I make it so pressing Enter in a textbox does the same as clicking the button next to it?

You could create a Keydownevent for the textbox and ask for the enter key:

private void TextBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
button1.PerformClick();
e.Handled = true;
e.SuppressKeyPress = true;
}
}
