However you insert data from a TextBox is exactly how you insert data from a CheckedListBox. Data is data. It's how you get that data in the first place that differs depending on the source. The Text property of a TextBox is a String. To get Strings for checked items in a CheckedListBox, do something like this:

foreach (var checkedItem in this.checkedListBox1.CheckedItems)
{
    MessageBox.Show(this.checkedListBox1.GetItemText(checkedItem));
}
