C#: Forms and if statements

I have a newbie question that's been bugging me. I've been messing around with forms in visual studio. In the simple program I'm making, I want to disable/enable a button depending on whether a checkbox is ticked.

Can someone tell me why this code doesn't work? Specifically the if statement.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    private void Form1_Load(object sender, EventArgs e)
    {
        Do_Check();
    }

    private void checkBox1_CheckedChanged(object sender, EventArgs e)
    {
        Do_Check();

    }

    private void Do_Check()
    {
        // button1.Enabled = checkBox1.Checked;

        if (checkBox1.Checked)
            button1.Enabled = true;
    }

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


}

I've commented out one way of achieving the desired result. I'm just not sure why the if statement doesn't also work. Any help would be appreciated.

Your button is only enabled if the checkBox1 is checked - but never disabled. Hence you should do something like this:

if (checkBox1.Checked)
    button1.Enabled = true;
else
    button.Enabled = false;

However, your commented solution with

button1.Enabled = checkBox1.Checked;

is way more elegant.
