    I'm in the middle of writing/adding features to my Fuelly app that I'm writing, and in a few places I use List Picker controls from the WindowsPhone Toolkit. The control appears to be very laggy even on my Lumia 1020. Is there any way to optimize the control, or an alternate that has better performance?

    Try using a list box in a separate panel for selection. I know LP is a data presentation control rather than item selection there are only a few ways to pick items.

    ComboBox is not recommended, I don't know if it is still alive.

    In addition can you please test this sample and see if the lag is persistent since most apps with list pickers work fine on my device

    The problem actually seems to be an issue with my device. It runs nice and smooth on the 512MB emulator, but a bit laggy on my actual phone.

    I couldn't get that sample to run, it had something hard-linked in it to whoever made the samples hard drive (the WMAppManifest.xml file to be exact).

    Hey,

    Those are the official samples from Microsoft and you can always check the sample validity and usefulness based on the rating. So by the manifest reference I understand you are using C#, I doubt that some thing is hard-linked like u sya, I just ran the sample on my PC which worked fine.

    You can always use RDA testing from Nokia, join the developer program at developer.nokia.com
