Suppose, I have the following DataGrid:

<DataGrid Name="customershowgrid"/>

How do I add the following list of objects to the customershowgrid DataGrid to display all the customer instances' attributes like name, phoneno etc.

What I have tried:

The following code generates empty rows and don't display any of the instances and/or their attributes:

List<AddCustomer.Customer> customers = new List<AddCustomer.Customer>()
{
    new AddCustomer.Customer()
    {
        _name="javed", _street="crib",
        _city="rwp", _state="punjab", 
        _phoneno="923340100321",
        _symptoms="none", _total="$399",
        _dateentered="2-Dec-2021"
    }
};
customershowgrid.ItemsSource = customers;
this.Show();

Does your Customer class contain "properties"?

yes it does like: public string name {get; set;} etc.
there are no compilation errors. it only does not show the output

from the code-behind, I think I have done that by doing:
this.customershowgrid.ItemsSource = customers;

The bound collection property has to be public, or it won't bind.

C#

public class MainWindow: Window, INotifyPropertyChanged
{
    // put your INotifyPropertyChanged implementation here
    //

    private ObservableCollection<AddCustomer.Customer> customers;
    public ObservableCollection<AddCustomer.Customer> Customers { get; set; }

    public MainWindow()
    {
        this.InitializeWindow();
        this.DataContext = this;
        this.Customers = new ObservableCollection<AddCustomer.Customer>()
        {
            new AddCustomer.Customer(){ /*set properties here*/ },
        };
     }
}

Set the ItemsSource in your XAML. You can use a List instead of an ObservableCollection, but if you do, you lose the ability of the GridView to update itself when the collection changes.

Based on your "field names" and your "property" reference (name {get;set;}) I would say you did not use the (private) "fields" as backing stores for the "properties", and you should be using "property names" in your initializer. i.e. new xxx() { name = "..." and NOT _name, etc. in this case.
