WPF - DataGrid only showing the properties of the baseclass

I am trying to fill a DataGrid with a List<> of multiple objects. These objects all inherent from a baseclass. I am successful in showing the columns and rows in the DataGrid, however I only see the properties of the base class and not the properties of the child class.

Unfortunately I could not find much helpful information while searching the web. But I am still new to WPF and C# so maybe that's the problem...

How can I get the DataGrid to show all of the properties, from both the base and child class?

EDIT: I have a few classes(say A, B, C) that inherit from the BaseClass and I have a list of the type List<BaseClass> which house multiple objects of multiple types. I need to show all the different child classes in my DataGrid.

I think you can bind your DataGridColumn which belongs to child classes.

object name of child class.property name of corresponding child class

<DataGrid ItemsSource="{Binding}">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding Prop1}" />
            <DataGridTextColumn Binding="{Binding Prop2}" />
        </DataGrid.Columns>
</DataGrid>

class Base
{
}

class Derived1: Base
{
    public string Prop1 { get; set; }
}

class Derived2: Base
{
    public string Prop2 { get; set; }
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    this.DataContext = new List<Base>()
    {
        new Derived1(){Prop1 = "Hello"},
        new Derived2() {Prop2 = "World"}
    };
}

This works for me. I see Hello in first row and World in second.

Try using a List<ChildClass> instead of a List<BaseClass>.

What is the T in your List<T> ? The type metadata is inferred from that (in winforms binding, at least; so I assume this applies to WPF too). So if you have a List<BaseClass> then only the properties of BaseClass will be shown. Try using a List<DerivedClass> instead.
