How to display data from the grid in wpf using back end?

Hi Team

I need help and want to improve my back end logic, when debugging its not displaying the data to the grid.

public void PopulateGrid()
        {
            Managers.BatchMaterialManager.SetAdriotConnection();
            var dtBatchRecipe = Managers.BatchMaterialManager.GetBatcherMatAndWbMat();
            DataView dv = dtBatchRecipe.DefaultView;
            Managers.BatchMaterialManager.SetDefaultConnection();

            /*try
            {
                dv.RowFilter = string.Format("CONVERT({0}, System.String) not like %PREMIX%");

                View.GridMacroRecipe.ItemsSource = dv;

                DataView dvPremix = dtBatchRecipe.DefaultView;
                dvPremix.RowFilter = string.Format("CONVERT({0}, System.String) like %PREMIX");
            }catch(Exception ex)
            {

            }
            */
        }
//user load control
        private void UserControl_Loaded(object sender, RoutedEventArgs e)
        {
            LoadControl();
            presenter.PopulateGrid();
           
        }

        // loads data to the server
        public void LoadControl()
        {
            Managers.BatchMaterialManager.SetAdriotConnection();
            presenter.PopulateComboBox();
            Properties.Settings.Default.Process = "Recipes";

            string[] arrayOil = RecipeName.Split('/');
            string OilIndicator = string.Empty;
            if (arrayOil.Length > 1)
            {
                OilIndicator = arrayOil[arrayOil.Length - 2].ToString();
            }
            else
            {
                // Handle the case where there is no '/' in RecipeName
                OilIndicator = ""; // Or set it to some default value or throw an exception
            }

            string LastDigit = string.Empty;
            if (RecipeName.Length > 1)
            {
                LastDigit = RecipeName[RecipeName.Length - 2].ToString();
            }
            else
            {
                // Handle the case where RecipeName is too short
                LastDigit = ""; // Or set it to some default value or throw an exception
            }

            if (OilIndicator == "2")
            {
                txtBagWeight.IsEnabled = false;
            }
        }


// front end wpf grid

You should follow the below steps to correctly the show the data from any backend in WPF application. I just mocked the data to show the example

Step 1: Create the Backend Data Source

Create a simple data source in the form of a list of objects. In a real application, this could be fetched from a database or a web API.

//Model
namespace WpfApp.Models
{
    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public decimal Price { get; set; }
    }
}

Step 2: Create the ViewModel

The ViewModel will hold the collection of products and provide it to the view.

// ViewModels/ProductViewModel.cs
using System.Collections.ObjectModel;
using WpfApp.Models;

namespace WpfApp.ViewModels
{
    public class ProductViewModel
    {
        public ObservableCollection Products { get; set; }

        public ProductViewModel()
        {
            // Ideally, you would fetch this data from a database or web service.
            Products = new ObservableCollection
            {
                new Product { Id = 1, Name = "Product 1", Price = 10.00m },
                new Product { Id = 2, Name = "Product 2", Price = 20.00m },
                new Product { Id = 3, Name = "Product 3", Price = 30.00m }
            };
        }
    }
}

Step 3: Set Up the View (XAML)

Create the XAML file for your main window and bind the DataGrid to the ViewModel.

Step 4: Bind the ViewModel to the View

In the code-behind of the MainWindow, set the DataContext to an instance of the ViewModel.

// MainWindow.xaml.cs
using System.Windows;
using WpfApp.ViewModels;

namespace WpfApp
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            DataContext = new ProductViewModel();
        }
    }
}

Step 5: Build and Run the Application

Compile and run your application. The DataGrid should display the products defined in the ViewModel.

Note that this setup provides only a basic but complete example of displaying data in a DataGrid in WPF using a ViewModel and data binding. You need to alter the code based on your requirment
