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

The .NET MAUI DataGrid supports binding the item source from a local JSON file.

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; }
}

Please place the JSON file in the 'Resources\raw' folder and ensure that the file's property is set as 'MauiAsset'.

OrderInfoViewModel

Read the JSON file using the FileSystem.OpenAppPackageFileAsync() method and 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())!;
    }

}
