    Rows

    There are two modes of rows virtual scrolling determined by the C1.Web.Wijmo.Controls.C1GridView.C1GridView.CallbackSettings property. The first one is static, when all the data are available to the client but rows are rendered when scrolled. The second one is dynamic, set by the C1.Web.Wijmo.Controls.C1GridView.CallbackAction.Scrolling value. New portions of data are requested from server when need to be rendered.

    Static mode cannot be used at the same time when paging, fixed rows or columns merging are used. Dynamic mode cannot work with columns grouping in addition.
