Question

Creating a Windows Forms Application in C#, I have a program that I am trying to insert a date into a text box (textBox3), and I can’t get the date to show up. I created a button on the form that pops up, and the date shows up just fine. But, the text box never populates. Any suggestions? Here’s the code:

    private void textBox3_TextChanged(object sender, EventArgs e)
    {
        var today = DateTime.Today.ToString("dd/MM/yyyy");
        textBox3.Text = today;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        var today = DateTime.Today.ToString("MM/dd/yyyy");
        MessageBox.Show("Today is " + today + ".");
    }

Your text field will only update when you start typing anything on the textbox because, apparently, you are hooking up to the Text_Changed event.

Type something in textBox3 and you’ll see that the text becomes whatever today is holding.
