Context Paging 

For performance reasons context paging is used to determine whether only a specific section of data should be kept in the context so that system performance is not affected. For example, you may want to display data from rows 10 to 20 only in a table.

Context paging is available for MultiPane and Table.

With the property firstActualxx you specify the cell (row) counting from 0 that is to be the first element in the context, and with xxCount you specify the number of cells (rows) that are to be displayed in the UI element.

With the onScroll event you can find out which data is to be displayed.

Note that with context paging not all the data in the context is available. This could cause problems, for instance with selection. For this reason you should only use context paging with very high data volumes.
