How to resolve SfSparkline not rendering issue in iOS and UWP

Platform: Xamarin.Forms |
Control: Sparkline |
Published Date: May 10, 2017 |
Last Revised Date: June 25, 2019

Description:

Xamarin does not load the renderer assemblies, by default, in iOS and UWP projects, so in order to solve this, you have to manually load it by calling Init method of SfSparklineRenderer class in the respective projects as mentioned below.

iOS Project

Call Init method of SfSparklineRenderer in FinishedLaunching overridden method of AppDelegate class in iOS Project as shown below,

C#:

public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{ 
       ... 
       Syncfusion.SfSparkline.XForms.iOS.SfSparklineRenderer.Init();
       ... 
}

 

UWP Project

Call Init method of SfSparklineRenderer in the constructor of MainPage in UWP project as shown below.

C#:

public MainPage()
{
       Syncfusion.SfSparkline.XForms.UWP.SfSparklineRenderer.Init();
       ... 
}
