ListView Problem

Hai All,

I have placed a ListView in the form,,And in a timer function Iam updating the values in the List View.

Updating is going on fine but i am getting flickering on the row iam updating.

Plz solve my problem ..How to get rid of the flickering...

I kept the timer interval as 50.That is mandatory in my app.

Thanx in advance...
