StrataListView performance VS SF Listview

Edhy Rijo — Thu, 26 Aug 2010 21:57:06 GMT

Does the new StrataListView in StrataFrame Expanded libary performs better when loading 1,000+ records than the standard SF ListView?

I have couple of forms in which the user requested to show all records in grid or view, since I have more control with the SF ListView I am using that, but performance is very slow when compared to a GridView, so I wonder if the new StrataListView will perform better?

Hi Trent,
Great, that is what I was expected to hear. I need this functionality in at least 4 forms, so manually binding won't be so hard, I will check the sample you posted a while ago to start up replacing the standard SF ListView with StrataListView. :hehe:

Edhy:

I have some screens that I load tens of thousands of records into it and it is fast. The reason is that it renders virtually without any configuration or coding on your part. This has become a staple control in MicroFour development by all internal coders, and it has worked really well and is extremely versatile! I have one app that has two and updates on threads and has progress bars in one column and massive amounts of data being dumped into another as a log. So I know it can handle high volume and perform fast. The difference is that the standard ListView doesn't virtualize by default and requires some additional coding to make it happen, and even still, it doesn't render perform as fast. Most likely due to the underlying API hooks that are in place by default.

Keith:

I know that this has been a long time coming on the data binding, and I have started it several times, but we have waited to make sure that there are no new features that would impact this. I believe at this point it is safe and so this is already on the short list....and is something that I have wanted numerous times as well...which helps the ranking in the queue ;)
