How to bind the ItemSource from a JSON file in a MAUI DataGrid?

The .NET MAUI DataGrid enables you to bind the ItemsSource from a local JSON file to display data dynamically. Below is a step-by-step guide to accomplish this.

C#

Create a JSON data model.

OrderInfo

public class OrderInfo
{
    public int OrderID { get; set; }
    public string? CustomerID { get; set; }
    public int EmployeeID { get; set; }
    public double Freight { get; set; }
    public string? ShipCity { get; set; }
    public bool Verified { get; set; }
    public DateTime OrderDate { get; set; }
    public string? ShipName { get; set; }
    public string? ShipCountry { get; set; }
    public DateTime ShippedDate { get; set; }
    public string? ShipAddress { get; set; }
}

Ensure the JSON file is placed in the Resources\Raw folder in your project and set its property to MauiAsset.

OrderInfoViewModel

Read the JSON file using the FileSystem.OpenAppPackageFileAsync() method and then deserialize the JSON object using the Newtonsoft.Json package.

const string templateFileName = "OrderInfo.Json";   

public async void LoadFile()
{
    this.OrdersInfoCollection = new List<OrderInfo>();
    using (var stream = await FileSystem.OpenAppPackageFileAsync(templateFileName))
    using (var reader = new StreamReader(stream))
    {
        this.OrdersInfoCollection = JsonConvert.DeserializeObject<List<OrderInfo>>(await reader.ReadToEndAsync())!;
    }

}
