SyncFusion chart integration with xamarin forms app

[Mohanraj]

Hi,

We are planning to integrate SyncFusion chart in our xamarin forms app. We followed the steps given in the document to create sample chart but when we build our application throws the following error,

"The type 'Xamarin.Forms.Platform.iOS.ViewRenderer`2<T0,T1>' is defined in an assembly that is not referenced. You must add a reference to assembly 'Xamarin.Forms.Platform.iOS.Classic, Version=1.3.4.0, Culture=neutral, PublicKeyToken=null'. "

sample we worked out is listed below

AppDelegate.cs:

In AppDelegate FinishedLaunching method we created SfChartRenderer instance as mentioned in the document. 

        public override bool FinishedLaunching(UIApplication app, NSDictionary options)

        {

            new SfChartRenderer();

            global::Xamarin.Forms.Forms.Init();

            LoadApplication(new App());

            return base.FinishedLaunching(app, options);

        }

Charts.xaml.cs:

public partial class Chart : ContentPage

    {

        public Chart()

        {

           // InitializeComponent();

            //Initializing chart

        SfChart chart = new SfChart();

        chart.Title= new ChartTitle(){Text="WeatherAnalysis"};

        //Initializing Primary Axis

        CategoryAxis primaryAxis= new CategoryAxis();

        primaryAxis.Title=new ChartAxisTitle(){Text="Month"};

        chart.PrimaryAxis=primaryAxis;

        //Initializing Secondary Axis

        NumericalAxis secondaryAxis=new NumericalAxis();

        secondaryAxis.Title=new ChartAxisTitle(){Text="Temperature"};

        chart.SecondaryAxis=secondaryAxis;

        DataModel dataModel=new DataModel();

        //Adding Column Series to the chart for displaying precipitation

        chart.Series.Add(new ColumnSeries(){

            ItemsSource= dataModel.Precipitation,

            Label="Precipitation",

            YAxis=new NumericalAxis(){OpposedPosition=true,

            ShowMajorGridLines = false}

        });

        //Adding the Spline Series to the chart for displaying high temperature

        chart.Series.Add(new SplineSeries(){

            ItemsSource= dataModel.HighTemperature,

            Label="High"

        });

        //Adding the Spline Series to the chart for displaying low temperature

        chart.Series.Add(new SplineSeries(){

            ItemsSource=dataModel.LowTemperature,

            Label="Low"

        });

        //Adding Chart Legend for the Chart

            chart.Legend=new ChartLegend();

            this.Content=chart;

        }

        

    }

    public class DataModel

    {

        public ObservableCollection<ChartDataPoint> HighTemperature;

        public ObservableCollection<ChartDataPoint> LowTemperature;

        public ObservableCollection<ChartDataPoint> Precipitation;

        public DataModel()

        {

            HighTemperature=new ObservableCollection<ChartDataPoint>();

            HighTemperature.Add(new ChartDataPoint("Jan",42));

            HighTemperature.Add(new ChartDataPoint("Feb",44));

            

            LowTemperature=new ObservableCollection<ChartDataPoint>();

            LowTemperature.Add(new ChartDataPoint("Jan",27));

            LowTemperature.Add(new ChartDataPoint("Feb",28));

            Precipitation=new ObservableCollection<ChartDataPoint>();

            Precipitation.Add(new ChartDataPoint("Jan",3.03));

            Precipitation.Add(new ChartDataPoint("Feb",2.48));

        }

    }

If anyone come across this issue kindly share or suggest me some ideas that would be helpful for me.  Thanks in advance.

Hi Mohanraj,

 

We would like to let you know that the problem is mismatching of Xamarin.Forms version, since we used Xamarin.Forms 1.3.4 version to build Syncfusion 12.4451.0.34 libraries. We will provide support for Xamarin.Forms 1.4.2.6355 version in our upcoming Service Pack release which is scheduled to release by end of this month.

Hi, I have the same problem, my error is 

The type 'Xamarin.Forms.Platform.iOS.ViewRenderer`2<T0,T1>' is defined in an assembly that is not referenced. You must add a reference to assembly 'Xamarin.Forms.Platform.iOS.Classic, Version=1.4.0.0, Culture=neutral, PublicKeyToken=null'.  ... in MyPath.iOS

I have SyncfusionEssentialStudio-13.1.0.30 installed, and my Xamarin.Forms version is 1.4.2.6359

Any suggestions?

[Contractor]

I should also add that I am not using iOS classic but Universal, with Xamarin Forms

[Contractor]

Problem solved, the give away was that I was using release 13.1.0.30 and yet the fix was in 13.1.0.26. I checked my DLL references and discovered that I hadn't referenced the iOS.Universal dlls. I'm a silly billy, aren't I :D

I'm having the same issue now with xamarin forms 1.5 and the latest release of sync fusion (13.3451.0.12)

[Manivannan Elangovan]

Hi Derrick,

Could you please ensure that you have referred the iOS dlls from the “ios-unified” folder? If you’re still facing the same issue after referring the dlls from the specified location, provide us more details regarding the issue which would be helpful to proceed further.
