You can't: if you have set a page size of 4 items, that that is all that the gridview will fetch - or there would be very little point in using paging to reduce the amount of data that needs to be transferred in the first place!

If you want all rows, then you have to go back to the original data source that the grid view was getting it's data from: the grid view itself can only show you the current page of values.
