Also, if the data source of your ListView is changed (e.g. if displaying data based on search parameters), don't forget to reset the pager every time the data source is updated. With a ListView this is not as straightforward as some other data-bound controls (e.g. GridView):

private void ResetListViewPager()
{
    DataPager pager = (DataPager)ListViewMembers.FindControl("DataPager1");
    if (pager != null)
    {
        CommandEventArgs commandEventArgs = new CommandEventArgs(DataControlCommands.FirstPageCommandArgument, "");
        // MAKE SURE THE INDEX IN THE NEXT LINE CORRESPONDS TO THE CORRECT FIELD IN YOUR PAGER
        NextPreviousPagerField nextPreviousPagerField = pager.Fields[0] as NextPreviousPagerField;
        if (nextPreviousPagerField != null)
        {
            nextPreviousPagerField.HandleEvent(commandEventArgs);
        }

        // THIS COMMENTED-OUT SECTION IS HOW IT WOULD BE DONE IF USING A NUMERIC PAGER RATHER THAN A NEXT/PREVIOUS PAGER
        //commandEventArgs = new CommandEventArgs("0", "");
        //NumericPagerField numericPagerField = pager.Fields[0] as NumericPagerField;
        //if (numericPagerField != null)
        //{
        //    numericPagerField.HandleEvent(commandEventArgs);
        //}
    }
}
