search results data grid refresh problem

Hi,

I noticed that when doing a search, after getting the results in a data grid and going to the next "page" of results (i'm showing only 20 out of very many, per page), if i do a new search, the new results are shown, but the user will not be redirected to the 1st page, he will still be in the same page of results (2 or 3 or so on).

Is this the normal behaviour or i did something wrong?

Thanks!
