C# type until you press enter

Question

I have Windows Form Application with TextBox and Label and I want to type something in the textbox and then press Enter to let's say show what I've typed in Label.

Example with button:

private void button1_Click(object sender, EventArgs e)
    {            
        this.Label1.Text = this.TextBox1.Text;
    }

I need to do exactly the same but with pressing Enter not button.

Answer 1

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        Label1.Text = TextBox1.Text;
    } 
}

Answer 2

I tried the code from Jan Anderssen and it works correctly. The error "Operator '==' can not be applied to operands of type 'char' and 'System.Windows.Forms.Keys" is because you are matching a character to Keys.Enter, make sure that the syntax is correct e. KeyCode.

E.KeyCode is used because in the event handler send a parameter with the value of e "KeyEventArgs e" variable and here is the key pressed.

private void txtText_KeyDown (object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter) 
{
this.lblText.Text = this.txtText.Text;
}
}

Did you copy and paste the code?

If so, try doing it with the events of the properties box. Click in the textbox -> Events ---> key down ---> double click and put the code there.

Do you have more than one form? This code may change.

Answer 3

you can use the text change event and check when enter pressed. when you identify enter, then you can do what ever you want
