I have done sorting in my gridview. It is woring properly.Suppose grid has 2 pages and size of page is also 2.Page contain 4 column.Out of 4 column,one column is name. First page contain 'archana' and 'bharti' name and second page contain 'pinky' and 'shweta'.When I sorting.Sorting should be done at page level.but this is not happening.'shweta' and pinky at first page then bharti and archana.In this order,sorting done.Not happening at page level.I want like, in first page,when I sorting 'Bharti' and 'Archana' should come and vice versa.
