Hi Quach Sy,

You're using an old version of UI for Xamarin, if you update to the latest you'll see it.  The reason for your issue is likely that you forgot to register the renderers in the native projects. Since R2 2017, you no longer needed to do this.

I strongly recommend that you update to the latest version as there are significant fixes and improvements since R1 2017. However, if you must stay on R1 2017, then follow the directions here (particularly, the renderers link underneath the assemblies list).

If you have any further trouble, please open a support ticket here and share the code with us. A ticket carries a guaranteed response from Telerik Support and you can attach project files.

Hello Crimsonlogic,

I was not able to replicate your issue, see my attached demo. In it I implement a simple demo using the Getting Started example.

             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:telerikInput="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.XamarinForms.Input"
             x:Class="R32017AutoCompleteTest.Portable.StartPage">
    <Grid>
        <telerikInput:RadAutoComplete BackgroundColor="White" x:Name="autoComplete" Watermark="Search here..." />
    </Grid>
</ContentPage>

public partial class StartPage : ContentPage
    {
        public StartPage()
        {
            InitializeComponent();
 
            this.autoComplete.ItemsSource = new List<string>()
            {
                "Freda Curtis",
                "Jeffery Francis",
                "Eva Lawson",
                "Emmett Santos",
                "Theresa Bryan",
                "Jenny Fuller",
                "Terrell Norris",
                "Eric Wheeler",
                "Julius Clayton",
                "Alfredo Thornton",
                "Roberto Romero",
                "Orlando Mathis",
                "Eduardo Thomas",
                "Harry Douglas",
                "Parker Blanton",
                "Leanne Motton",
                "Shanti Osborn",
                "Merry Lasker",
                "Jess Doyon",
                "Kizzie Arjona",
                "Augusta Hentz",
                "Tasha Trial",
                "Fredda Boger",
                "Megan Mowery",
                "Hong Telesco",
                "Inez Landi",
                "Taina Cordray",
                "Shantel Jarrell",
                "Soo Heidt",
                "Rayford Mahon",
                "Jenny Omarah",
                "Denita Dalke",
                "Nida Carty",
                "Sharolyn Lambson",
                "Niki Samaniego",
                "Rudy Jankowski",
                "Matha Whobrey",
                "Jessi Knouse",
                "Vena Rieser",
                "Roosevelt Boyce",
                "Kristan Swiney",
                "Lauretta Pozo",
                "Jarvis Victorine",
                "Dane Gabor"
            };
        }
    }


Next Steps

Without seeing your code, I can't determine what the problem is. The first thing to check is to make sure you're using all the required dependencies (you can find the list here).

After you've added the dependencies, make sure you're doing a Solution > Rebuild to ensure that the newly added code is deployed. Xamarin Android is set to Fast Deploy by default, which sometimes doesn't deploy newly added code.

If you want to diable Fast Deploy, you can find the setting here:




Further Support

If you still have issues after confirming you have the dependencies; please open a support ticket here, mention what SDK you're using, what device you're targeting and attach either:

- A runnable project that replicates the issue
OR
- Attach the files for the view that contains the RadAutoComplete (view, view model and code-behind).

Either I, or one of my colleagues, will review the code and follow up with you within the ticket's timeframe.

Hello Crimsonlogic,

Yes, the code is the same, no matter what version of Visual Studio you are using.  You can also go here to the Getting Started article in the documentation. That is the example that is being used in my previously attached project.

If your code is not working, please follow the instructions I placed under the "Further Support" section in my last reply. Because by itself, the RadAutoComplete works, so there might be other factors in your View/ViewModel that is causing the problem.

I will see your support ticket come in, with the attached files, and I'll be able to investigate further.
