Do at least Visual studio 2005 have a solution for asynchronous data view in the grid Stock market quotes update in the web-based grid.

I was told by my superiors to include following features in the website, I decided to develop with visual studio 2005 and sql server 2005.

Following features needed to be fulfilled, can you please give me guidance, and does VS2005 Grid view can fulfil this requirement . Can u give me an idea pls

  1. Asynchronous data updating features like Ajax
  2. Paging, Data sorting, data searching
  3. Colour cell indicators when the data update in the grid.
  4. Server processor shouldn’t be stress no matter how many clients access the web page.
  5. Have to do all this with in IMB SDSL Internet Band widths

So far I have tried

  1. By using XMLHTTPRequest periodic sql query excution from single table, retun only 10 rows of data cause the sql server 2005 exe to overload and not able to server more than 30 clients (Testing)
  2. By TCP/IP Socketing unable to meet up the above requirement
  3. Client pulling delimited text file (78kb size file) from server cause the bandwidth-sharing problem.

After trying all these method.

I want a grid who can able support all these features efficiently, java applets cant able to meet up this features too. Finally I descided to give a try with VS2005 data grid. Please advise or give me some idea over this.

Stephen,

ASP.NET GridView control does not provide an integrated "ajax" like functionality... so it handles all its events on the server.

There are different approaches you can take at this moment:

1. Use ASP.NET 2.0 Callbacks and HTML DOM to create a custom made, ajax-enabled GridView

2. Use a third-party ui controls package (buy) that includes this functionality... for example ComponentArt WebUI or Infragistics... etc

3. Use some ajax framework along with the ASP.NET GridView control.... for example you may use ComfortASP that allows you to keep working with "post-backs" but it automatically converts it in callbacks.

4. Go a step further and use MS ATLAS (beta)

You may also find more answers on that on : http://forums.asp.net

Hope it helps
