Question

I have a quick and simple question on a small project that I’m starting out on my own in C# for a Windows form program with Visual Studio 2010. I can’t seem to find the correct code to transfer the input data that a user enters into a textbox with a method where they hit the enter key and it automatically enters a message in that label on the same form.

Such as in the following code (which has been edited as suggestions are provided):

    namespace MovieFinders2
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }

            private void label1_Click(object sender, EventArgs e)
            {
                //Named "Enter a Year"
            }

            private void textBox1_TextChanged(object sender, EventArgs e)
            {

            }

            void textBox1_KeyDown(object sender, KeyEventArgs e)
            {
                if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return)
                {
                    label2.Text = textBox1.Text;
                    label2.Text = "Movies released before " + textBox1.Text;
                }
            } 

            private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
            {

            }

            private void label2_Click(object sender, EventArgs e)
            {
                label2.Text = textBox1.Text;
                label2.Text = "Movies released before " + textBox1.Text;
            }

            private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
            {

            }

            private void label3_Click(object sender, EventArgs e)
            {
                label3.Text = textBox1.Text;
                label3.Text = "Movies released in or after " + textBox1.Text;
            }
        }
    }

            private void label3_Click(object sender, EventArgs e)
            {
                label3.Text = textBox1.Text;
                label3.Text = "Movies released in or after " + textBox1.Text;
            }
        }
    }

I know that this program is in the early stages, but I”m trying to take this one step at a time and this is the road block that I have encoutered at this point; so any and all help would be greatly appreciated. Right now when I click the mouse on the lable it displays the message in that label. I need this to appear in the label when the user presses the enter key.

Try this:

void textBox1_KeyDown(object sender, KeyEventArgs e) {
    if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return) {
        label2.Text = textBox1.Text;
        label2.Text = "Movies released before " + textBox1.Text;
    }
}

TextBox.KeyDown event
