OK ... I assume this means that you are actually needing to databind to a string?

This CheckBox binds directly to your DataColumn rather than an intermediary property (which can be done too, but takes more code IMHO). This class can be extended to be able to used with other strings, such as T/F, but I’ll leave that as an exercise for the reader:

public class BBCheckBoxString : System.Windows.Forms.CheckBox
{
	protected Binding oBinding = null;

	public virtual void DataBind(System.Data.DataTable Data, string Column)
	{
		this.Checked = false;
		this.oBinding = new Binding("Checked", Data, Column);

		this.oBinding.Format += new ConvertEventHandler(this.FormatHandler);
		this.oBinding.Parse += new ConvertEventHandler(this.ParseHandler);

		this.DataBindings.Add(this.oBinding);
	}
	protected override void FormatHandler(object sender, ConvertEventArgs e)
	{
		if (e.Value.ToString() == "Y")
			e.Value = true;
		else
			e.Value = false;
	}
	protected override void ParseHandler(object sender, ConvertEventArgs e)
	{
		if ((bool)e.Value == true)
			e.Value = "Y";
		else
			e.Value = "N";
	}
}

Then, on your Form or control, to databind that Checkbox, you’d do this:

this.MyCheckBox.DataBind(MyTable, "MyYNColumn");
