Sort Datatable / Dataview / Gridview Of Files Based On File Modified Date?
Aug 2, 2010I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.
I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).
If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?

But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET

State Management :: Application Error "datatable Must Be Set Prior To Using Dataview "?
Jul 29, 2010I have developed a website in asp.net 2.0 with backend MS SQL server 2005. After each 2-3 days when i try to login to my admin panel i get a /server application error "datatable must be set prior to using dataview ".When I made a research on this i found the error is in the caching part of the code where i am using a dataset to fill my dropdown lists. But I am using the same code everywhere and on other place i didn't get any error but on a specific page. i usually get error when i try to login to admin. After successful login i redirect the admin to a page adminBazaar.aspx. and the error is always thrown by dis page only.other pages with the same code are working fine and there are no issues.I am using SqlCachingDependency. but can't figure out how to solve the problem.Right now to solve this I have to go to the server stop the website,then stop the application pool and the restart both. We have created a separate application pool for the website.
