TActivePager Sample

+

+The following sample displays three different pagers associated with a single TDataList control. The datalist control is enabled with custom paging, which allows it to read only one page of data each time. This is typical in DB-driven applications. +

+ +
+Go to page: + + + Element.show('wait') + + + Element.hide('wait') + + + +
