    Hello,

    I'm using your RadListView and I noticed that I have poor performance when I scroll it at the first time I enter in a page.

    After the first scroll all seems to be more smooth, but if I go out and the re enter inside the same page I still have the same problem.

    This is really bad because the user have a poor user experience using the app; I remember that xamarin suffred of this problem some times ago, but it was solved introducing the caching strategy option.

    What is the way offered by telerik to manage this problem?

    I wasn't able to find info neither looking in the forum nor in documentation, thank you

    Hi Fabio,

    Thank you for contacting us.
    Would it be possible to share some additional information regarding the platform and setup of the listview, the way the itemtemplate is defined and does it contains images.

    Hi, I was usingXamarin Forms 2.3.0.107 with the previous release of telerik.

    Now I'm facing with a new problem: I updated the telerik component to newest version and xamarin to 2.3.1.114, and all my environment was broken.

    I'm currently unable to compile the project, because Visual Studio show me a lot of errors regarding some java component not found.

    Now I'm reinstalling android sdk, I already removed all telerik components, xamarin forms packages and reinstalled all, without luck.

    My itemtemplate is defined in an external file xaml and it doesn't contain images.

    Hello Fabio,

    Thank you for sharing this additional information. If you encounter issues with updating Xamarin Forms make sure you check their troubleshoot section - https://developer.xamarin.com/guides/xamarin-forms/troubleshooting/

    Upgrading our suite only updates the dlls located in [Program Files (x86)]\Telerik\UI for Xamarin R3 2016\

    Regarding the item template I can suggest the following steps:
     - make sure you have enabled Xaml compilation - https://developer.xamarin.com/guides/xamarin-forms/xaml/xamlc/
     - consider simplifying the layout of the template.


    If this does not help please share the setup so we can suggest the most appropriate course of action.

    Thank you, I will try compiling Xaml, is not yet enabled on my project.

    Layout of cells is really easy, I can't simplify more.

    I will rewrite here when I will try with Xamlc, thank you
