Telerik Rad Grid Control PageSize Issue

Question

I am using a RadGrid (Telerik.Web.UI.dll version 2010.2.929.35) control with default PageSize as 5 .

When the user select page size 10 and click on next page , the page size which we have selected (10)is changing back to the default one(here 5).

How we can maintain the page size selected by user in different pages?

Please help me to resolve the issue.
