    Is there a way to use stealth paging/scrolling with RIA services and Telerik GridView and Listboxes? Or are there plans to support stealth paging?

    Hi Stefan,

    What do you mean by stealth scrolling?

    Are you referring to something like this or this? Or do you mean deferred scrolling?

    Stealth paging refers to the concept of retrieving data in background just before it is needed. You start by loading DataGrid with only one or two pages worth of data, just enough to cover the screen and some more. Now when user starts scrolling, and nears the end of available rows to show, we fetch additional data and add it to the data collection. User continues scrolling, without ever realizing that data was fetched in the background.

    ComponentOne has an example of this technique:

    You see this technique more and more in smartphones and tablets. When using a touch enabled device stealth paging is a lot easier for the user then paging with a datapager. I was wondering if the Telerik controls support this feature.
