We need to load data from two tables (SQL 2005) into the web grid, when the user loads the webpage.
Some unbinded fields (numeric and blank until data is available) have to be posted to the user when external data is received without reloading the page.
This is a low latency application so when new data is available should be displayed and broadcasted to everyone as fast as possible (milliseconds).
The application should support hundreds of concurrent users visualizing the grid, receiving the new data without losing performance.
The live data is released by an existing .Net 4.0 C# application (local, running on the same server that IIS runs on)
Several items can be released at the same time (within milliseconds) and the application needs to handle this.
Skill Require - ASP.NET 4.0, C#, Ajax
All source codes and rights should belong to us.
Code should be maintainable and understandable.
1) The database size has thousand of records now, but only a few needs to be displayed on the grid at a time. (about 50 records, showing the events for the current week).
2) The data in the grid is the same for all users, but they should be able to filter the events:
by country: only 10 available
by date: each day of the week (for the current week), or show the whole week.
3) The other application is responsible for updating the DB with the new information, so you don't have to worry about this.
4) The events should be displayed in the users' local time, and the user should be able to change the time zone of displayed data.
We can modify the source application in order to call and insert the new data in the grid, you sould build a sample application (c#) to show us how (you are free to do this the way you want as long as it's efficient). Only keep in mind that the grid has to be able to receive and update several fields whithin milliseconds once data is available and sent to the grid.
Your application should provide some access to the source application... some function like insertNewData(int id, double value);
Where id is the primary key of DB and identifies the row in the grid, and value is the new data to up displayed in the grid.
