Hi,
My requirement is “Initially bind first 10 records to the datagrid. On scrolling the scrollbar need to bind another set of records. Scrolling should be on both upwards and downwards. Another requirement is I need to implement Server-Side Sorting on datagrid”.

Please do help me in this.

Thanks in advance…

A little late to this convo but …

I’ll list my reasons:

1. It’s easier to program. Paging is a pain in the ass. At least currently. If I want to “see all the records in category xyz” then show me them. It is easier to take the recordset and bind it to the datagrid.

2. Scrolling is easier than paging. In HTML you just output the data to a table and use the scroll bar. Since it’s usually sorted alphabetically or numerically you can find what you are looking for much faster. Or use ctrl + f to find the record on the page.

3. Paging is a hack (sortof). Paging is a way to handle a limitation of the hardware or network. Computers will get faster and 1 million will be normal and we will be told to page 1 billion records. Paging is a way to handle large amounts of data over the network. It is a way to handle the model more than a design choice of the view.

Gotta agree with an earlier post about using flash to do large data display being irresponsible. It’s all about the right tool for the right job.

Millions of records? Don’t use a web app. Use a desktop application that can handle it, sure read the data from the intranet DB, but don’t use flash for this. Crazy.

Look into REALBasic and Einhugur’s datagrid. It can handle enormous amounts of data. The trick it uses is it only displays and stores what has been requested (IE you scroll and it fires an event saying ‘I need Row X’s data when Row X comes into view) so at most you’re looking at 20 requests at a time. Pretty nifty if you ask me.

Hi,
When I first loaded my flex datagrid with 190 records I was really disappointed. It was almost impossible to scroll tha grid or resize it. It seems like flex components are much slower than flash components. What is the reason??

Well, actually there is a good reason to load a datagrid with thousands of records. Some sales type applications want to show quantity and give the customer the ability to narrow or expand results on the fly. Granted, this should not be common practice, but considering the context, the customer is always right.

So, is there a way to load thousands of records, 9 columns, all sort enabled and Flash to fizzling to a halt? :-)
