How to Resolve DataGrid not Rendering Issue in Xamarin?

Xamarin does not load the renderer assemblies, by default Xamarin DataGrid, in iOS and UWP projects. Hence, to solve this, you need to manually load it by calling the Init method of SfDataGridRenderer class in the respective projects as mentioned below.

iOS Project

Call SfDataGridRenderer.Init() method in the FinishedLaunching overridden method of the AppDelegate class after the Xamarin.Forms Framework initialization and before the LoadApplication is called, as demonstrated in the following code example:

public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    Xamarin.Forms.Forms.Init();
    
    ...
    Syncfusion.SfDataGrid.XForms.iOS.SfDataGridRenderer.Init();
    ...
    
    LoadApplication(new App());
    return base.FinishedLaunching(app, options);
}

UWP Project

Call the SfDataGridRenderer.Init() in the MainPage constructor before the LoadApplication is called, as demonstrated in the following code example:

public MainPage()
{
    
    ...
    Syncfusion.SfDataGrid.XForms.UWP.SfDataGridRenderer.Init();
    ...
    
    LoadApplication(new App());
}
