I have a text box and a crystal report viewer in a windows form.

As user types in some text in text box, it should immediately display in report viewer. I have done this, but I have problem here, that is "If user types too quickly then refreshing of the preview screen is fine, but if user type slowly then text is lost"

I am not able to find a solution to this problem.
I tried with multithreading, with timer but could not able to implement it.

can someone please help me in this?

Thanks in advance
