Map is not showing

[qwert]

I have followed the guide https://docs.telerik.com/devtools/maui/controls/map/getting-started to integrate maps into my app. However, all I get is an empty white rectangle.

MainPage.xaml:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:telerikMap="clr-namespace:Telerik.XamarinForms.Map;assembly=Telerik.Maui.Controls.Compatibility"
             x:Class="MauiApp1.MainPage"
             BackgroundColor="{DynamicResource SecondaryColor}">

    <ScrollView>
        <Grid RowSpacing="25" HorizontalOptions="Fill" BackgroundColor="LightBlue" RowDefinitions="Auto, auto"
              Padding="{OnPlatform iOS='30,60,30,30', Default='20'}">
            <Grid Grid.Row="0" HeightRequest="600" BackgroundColor="Green">
                <telerikMap:RadMap x:Name="map" AutomationId="map">
                    <telerikMap:RadMap.Layers>
                        <telerikMap:ShapefileLayer>
                            <telerikMap:ShapefileLayer.Reader>
                                <telerikMap:MapShapeReader x:Name="reader"/>
                            </telerikMap:ShapefileLayer.Reader>
                        </telerikMap:ShapefileLayer>
                    </telerikMap:RadMap.Layers>
                </telerikMap:RadMap>              
            </Grid>                     
        </Grid>
    </ScrollView>
</ContentPage>

MainPage.xaml.cs:

using Telerik.XamarinForms.Map;
using Telerik.XamarinForms.ShapefileReader;

namespace MauiApp1;

public partial class MainPage : ContentPage
{
	public MainPage()
	{	
		InitializeComponent();

		var assembly = this.GetType().Assembly;
		var source = MapSource.FromResource("SDKBrowserMaui.Examples.MapControl.world.shp", assembly);
		this.reader.Source = source;

		Console.WriteLine("Source: " + source + "Reader: " + this.reader);
	}
}

Output:

Source: Telerik.XamarinForms.Map.StreamMapSource Reader: Telerik.XamarinForms.Map.MapShapeReader

Hi qwert, 

I assume the reason behind this behavior is because you use wrong resource location.

You use this code:

var source = MapSource.FromResource("SDKBrowserMaui.Examples.MapControl.world.shp", assembly);
this.reader.Source = source;

The text marked in yellow is the location of the world.shp file. It is inside the MapControl folder. The example provided in the Getting Started article load.shp files as an embedded resources.  

You have to add the correct path where the .shp file is located in your project.

Regards,

Didi
