C# Checkedlistbox Control

[TitusRevised]

using Visual C# 2005 Express Edition:
I have a checkedlistbox control on a form.
I have a button on the form.
In the buttons on click event, I want it to automatically check all the items in the checked list box. A check all/select all button.

How do I do this?

nevermind, i figured it out finally.
Just had to make a loop.

private void button4_Click(object sender, EventArgs e)
{
for (int c = 0; c < checkedListBox1.Items.Count;c++)
{
checkedListBox1.SetItemChecked(c, true);
}
}
