Both the Flexicious basic and advanced datagrids expose a property, filterPageSortMode.
This is a key property to understand. There are two values for this property, “server” and “client”. Let us assume you are working on a Human Resource Management Application. You have a DataGrid that shows a list of Employees. You have a few hundred Employees to show. This can be easily accomplished by getting the list of employees from the server, and setting the data provider property of the ExtendedDataGrid to an ArrayCollection that contains this list of Employees. As you need, you enable filters, footers, paging, export, print, etc, and all is well and good. You will be up and running in no time with filterPageSortMode=client. The grid will take care of paging, filtering and cross page sorting for you. However, now consider a scenario where you have to display a time sheet search page. Each employee creates hundreds of timesheets each year, and multiply that by the number of employees, you are looking at thousands, even hundreds of thousands of records of data. Although it may be possible to load thousands of records in any Flex DataGrid (including ours) with no noticeable drag, this is not recommended, and often unnecessary. What we suggest in this scenario is you use the filterPageSortMode =”server”. What Flexicious does, in this setup, is it assumes that the current ArrayCollection is a part of a much larger recordset, and you are showing just the current page of data. So if there are 100,000 records in the database, and the pageSize is 50, Flexicious will show the 50 records, and provide paging UI for the user to navigate to any record in the resultset. At any point in time, no more than 50 records will be loaded on client memory. This setup, will require a little more effort in terms of configuration, but it will be considerably easier to do this with Flexicious as opposed to building it yourself, because the product is architected to cater to a scenario like this.
We provide complete examples on how to do this, including the backend code in Java and .Net.
