generate EventHandler from string?

Hi,
I want to generate a eventhandler from a string that comes from a sql table.
Let`s say I want to a a TextChanged Event on a TextBox like this
string sEventHanler = tb.Record
TextBox tb = new TextBox();
tb.TextChanged += new System.EventHandler(sEventHandler)
I know that this wont work, but is there a way that I can convert tb.Record to a EventHandler?

Best regards,
Mark
