Hi,

I am facing memory leak problem when using SF BusinessObject and DevExpress ASPxDataGridView.

I have simple test project, which only has one BO, bind to ASPxDataGridView. It does nothing complicated, just load all records in Page_Load if not IsPostBack.



I found that, the memory usage would become double when I just "refresh" the page. I also used dotTrace profiler and found that # of BO instances keep increasing. I suspect it is the same issue with the post http://forum.strataframe.net/Topic20903-8-1.aspx.



I have prepared sample project and the dotTrace memory profiler files for your reference. MemoryLeak1.dtm is first load memory snapshot and MemoryLeak2.dtm is 2nd snapshot after refresh.



As the file size > 30MB, please download it from http://www.visualsolutions.com.my/blog/chankk/WebApplication6.zip



Hope you could get back to me as soon as possible! It is very urgent!



Thank you

Hi

Chan,

For whatever this is worth, we have not changed anything in this regard.  I am willing to bet that you have an old assembly someplace, or something within your environment has changed.  I will look at this, but I find it strange that this would just suddenly "reappear."

Chan,

I am confused as to what your application is trying to do.  You supplied the nwind.mdb database, but your connection string is an SqlDataSourceItem (not Access), so I am not sure what database I am supposed to connect to.  Since your test app is wired to look at an SQL database I am assuming that you have an MDF somewhere that I should be connecting to.  I will look through all of the attached files again, but please advise.  Thank you.

Just to update you, I noticed that the nwind.mdb table name was Employees (with an "s") and your BO was mapped without the "s".  Changed this and it still did not work.  45 minutes into it and still can't make your sample work.  Sorry.  I am going to wait until I receive more details about what database I am supposed to connect to.

One other thing I noticed is that this is not a StrataFrame wired web application.  Clearly you can do this, but you may have Session issues, etc. since we wire things up through the ApplicationBasePage and the global.asax.  I noticed that you created your own TestBasePage.cs....this is really not related to the issue, just an observation.

Awaiting further instruction.  Thanks.
