Hello Bhaskar,
Just out of curiosity, is there a good reason why you don't want to use the SimulateRealTyping property? I'm asking you because it seems that there is an event attached to that TextBox control that needs to be triggered and the best and easiest way to do this is by turning on the SimulateRealTyping. The other option is to trigger this event using code as described in
this article.
