blinking data gridview

Dear Friends,

I'm working on a .NET web application wherein I have a gridview.

Now there is a No_of_pairs column in the gridview which contains a number . The requirement is for the rows of a gridview to blink if the  column for those rows has a value less than 120. So all the rows in the grid where the  column has value < 120 should blink.

So let's say the first time when the page loads only the first five rows of the gridview are blinking (since they satisfy the above condition). Now after the gridview gets refreshed, two more rows get added from the DB and they satisfy the condition above. So in this case, the previous five rows plus the two new rows (7 in total) should blink.

I tried all sorts of javascript function but couldn't achieve this requirement. Can someone help me out with this??

Plz Reply soon Its Very Very Argent

Thanks in advance
