India is thrilled with the news about winning gold medal in Olympic Beijing 2008. Mr Abhinav Bindra bagged gold medal in the men's 10m air rifle event at the Beijing Olympics.

Almost after a month I am able to revitalize noesispedia. I just changed my host provider. I don't have words as how bad my experience with www.webhostasp.com was. Anyway so here is the latest update. The site has been moved to latest blogengine release i.e. 1.4.5. I have modified the code to support multiple instances of the application using same db. Ofcourse having different tables for different application is a solution but I personally don't like the idea. I will soon publish the modification to run BlogEngine in multiple environment mode. I hope the readers, I know there are very few, will find that the page loads faster now. Let me know if you still face some issues. 

Cheers! 

Today I came across a very interesting article and would like to share

 How: milk contains a protein called casein, which, once reduced with a little vinegar, can be made into a homemade plastic . nice

Earlier I posted about how to dynamically sort the data using extension method see this http://www.noesispedia.com/post/2008/03/21/Linq-to-Sql-Dynamic-Sorting-without-using-Complete-Dynamic-Linq-Libraries.aspx

In this post I will present a quick solution to sort a list of object based on a property of object.

Suppose you have an object like

   1:   

   2:  public class MockObj

   3:  {

   4:  prop a

   5:  prop b

   6:  prop c

   7:  prop d

   8:  }

If you are binding above object with gridview (List) and you want to enable sorting in gridview onsorted event use following code to sort

   1:   

   2:  protected void gv_OnSorting(object sender, GridViewSortEventArgs e)

   3:  {

   4:  if (SortDirection == SortDirection.Ascending)

   5:  ((GridView)sender).DataSource = List.OfType().OrderBy(mo=> mo.GetType().GetProperty(e.SortExpression).GetValue(mo, null));

   6:  else

   7:  ((GridView)sender).DataSource = List.OfType().OrderByDescending(mo=> mo.GetType().GetProperty(e.SortExpression).GetValue(mo, null));

   8:  SortDirection = SortDirection == SortDirection.Ascending ? SortDirection.Descending : SortDirection.Ascending;

   9:  ((GridView)sender).DataBind();

  10:  }

Note that sortExpression specified in gridview must match with one of the property on the object.

If you don't want to use this quick but dirty solution you can go for extension methods. For more information see following links

Thanks to my friend Joseph for giving this solution and saving time in writing case statements :-) 

Hope this helps!
