How to sort name by alphabetically in drupal views? I have created view in this drupal 7 views,there are Two pages are created in that view.

page 1:Images page
page 2:List view page

here i have tried in List view page by using sort criteria of Name field(ASC or DESC). but Names are sorted in List view page correctly.

When i am click Name field for sorting in second page(List view) automatically that fields are sorted in first page(Images) page also.
That sorting is not working in views.
First page taking only default sorting order.

Here is screen shorts


Here sorting values are not stored database permanently.If i click refresh button views default sorting behavior is added to that pages.
Is it possible to sort the two view pages permanently?
we have a module called Views Glossary once u install the module we have to enable in stucture->views->glossary view like archive for dats and months
