>Can you demonstrate how you would do so for a base textbox class, for example?

Sure Mike ... simplified version:

m_BoundTable and m_BoundColumn are fields that are exposed as public properties, so they can be set in the Property sheet if you wish.

public virtual void DataBind(System.Data.DataTable Data, string Path)
{
	for (int i = 0; i < this.DataBindings.Count; i++)
	{
		if (this.DataBindings[i].Equals(this.oBinding))
		{
			this.DataBindings.Remove(this.oBinding);
			break;
		}
	}

	this.Text = "";
	this.m_BoundTable = Data;
	this.m_BoundColumn = Path;
	this.oBinding = new Binding(this.m_BoundProperty, Data, Path);
	this.oBinding.Format += new ConvertEventHandler(this.FormatHandler);
	this.oBinding.Parse += new ConvertEventHandler(this.ParseHandler);
	this.DataBindings.Add(this.oBinding);
}
