Grabbing Data On The Fly - Some methods for passing data around

(Page 2 of 6 )

There are three well-known methods that are used to gather data, and return results to the user, these are:

1. Remote Scripting Technologies
2. Collect users query on one page, and return the results in another
3. Submit users query to the same page

As with any web technology, though, each method has its drawbacks:

Remote Script:

• Remote scripting is very hard to debug and maintain
• Sometimes, the performance of remote scripting is appalling

Collect in one, query in another:

• The number of pages increases quickly
• If the form contains a huge number of variables that need to be stored, then we may need to enable session state
• Hard to maintain

Submit users query to same page:

• The page size may become large and contain too much logic
• As a result, managing code would turn into a nightmare

There is, however another way to handle data submission and retrieval without refreshing the page or using session state. We can use a hidden frame.
