Hi,

I have a reasonably easy question but can't seem to get it right:

I have a textbox in my form (textBox1), when the enter key is pressed it should enter the text in the textbox in a listbox(listBox1)

How can i make it enter the text in the listbox (once for every enter pressed)?

You can use the KeyUp event of the textbox.

Regards,
Bruce
private void textBox1_KeyUp(object sender, KeyEventArgs e)
{
    // check the key and just act if return (or enter) was pressed
    if (e.KeyCode == Keys.Return)
    {
        listBox1.Items.Add(textBox1.Text);
        // clear the text box or just comment out the next line 
        textBox1.Clear();
    }
}

Hi, thanks for the reply,

apparently I was close but when I did paste your solution and ran the program it didn't enter the text when the enter key was pressed. I tried assigning other keys to the 'if' statement but same result.

Am I forgetting something? It also doesn't clear the textbox as it doesnt seem to accept the enter action
