    [CLOSED] source code for Transformer.NET.dll

    Hello:

    Where I can find the source code for Transformer.Net.dll?

    I am testing the limits of how much data I can return in a gridpanel, and basically, I start getting OutOfMemoryException when I have approx 140 columns & 560 rows. I don't have yet a sample project that I can pass to you, but I was curious to look at the source code to see what Transformer.Net does. I am a bit surprised about the OutOfMemory exception, I would have thought that a gridpanel + store with 140 columns x 560 rows would be fine.

    Hi,

    Transformer.NET source is available at the following location:

    https://github.com/extnet/Transformer.NET

    There is a lot of regex action happening in Transformer.NET, so pushing through 78400 (140 * 560) points of data may be pushing the limits.

    How about async loading the data? I'm assuming you're binding the data during Page_Load?

    The issue is fixed in latest code already. Now data is injected after Transformer logic
    Please update from SVN and retest

    @Vladimir:

    Is it fixed in 2.1 or in the latest 2.2 ? If I were to upgrade to the latest 2.2 would this problem be solved?

    @geoffrey.mcgill:

    I use MVC and the store is bound to a DataTable object. The data in the store is returned along with the rest of the page. It crossed my mind as well to load the store data asynchronously but it is a bit of refactoring.

    Thank you

    It is fixed in 2.2 (not 2.1)
