The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

AdvancedDataGrid load on demand

Asked by Hamlet in Adobe Flex

Tags: Flex

I am porting an HTML type app across to Flex, and am trying to decide the best way of handling data browsing.

For certain types of data (e.g. Customers) there can be a large number of records, so pulling across all the records for browsing is impractical.

I have considered a couple of options, and would like some feedback on them or any suggested alternatives.

1. Page at a time.

This is essentially how the existing system works. It figures out how many rows it has room for, asks the server for the total number of records, and then splits it into pages. That way only a small number of rows (e.g. 30) are pulled across at a time, and tabs are shown at the bottom allowing the user to navigate to any of the available pages. When they click a tab then that page of data is pulled from the server.

2. Populate with blanks, only retrieve visible records.

The idea here is similar but would allow the user to scroll through the data rather than just viewing a single page at a time. Ask the server how many records there are. Create that many blank records. Get enough data to fill the visible rows. When the user scrolls get the required data (or potentially just do this in the background).

Option 2 seems more appealing, but both options limit the ability to make use of the AdvancedDataGrid column sorting.

Is there a nicer way of doing this?
