How to display class attributes for a class object initialized in XAML

I have a class Employee in a WPF Project:

class Employee
{
    public int ID { get; set; }
    public string Name { get; set; }
}

And I am creating an instance of it emp2 in my XAML file:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:WpfApplication1"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <local:Employee x:Key="emp2" ID="20" Name="Second Employee "></local:Employee>
    </Window.Resources>
    <StackPanel>        
        <Label x:Name="lblEmpInfo2" FontSize="18" Margin="20" Content="{StaticResource emp2}"></Label>
    </StackPanel>
</Window>

However this only displays the datatype of emp2 i.e. WpfApplication1.Employee. How do I display the ID and Name of emp2

You have multiple options:

  1. Use DataTemplates (MatthiasG's answer)

  2. Quick and dirty: Implement ToString() in class Employee, simple but not very flexible.

  3. Use StaticResource as Binding Source:

    <StackPanel>
  <Label Content="{Binding ID, Source={StaticResource emp2}}"></Label>
  <Label Content="{Binding Name, Source={StaticResource emp2}}"></Label>
</StackPanel>

Your binding's just a wee bit off:

<Label x:Name="lblEmpInfo2" FontSize="18" Margin="20" Content="{Binding Source={StaticResource emp2}, Path=ID}"></Label>

Like this:

<Label x:Name="lblEmpInfo2" FontSize="18" Margin="20" Content="{Binding Path=Name, Source={StaticResource emp2}}"></Label>

Or implement the ToString method override of the Employee class

public override string ToString()
{
    return string.Format("{0} {1}", Id, Name);
}

WPF uses the concept of DataTemplates to give you the possibility to decide how data objects should be presented. Therefore you could define a DataTemplate for the class Employee and then use a ContentControl which uses the instance of the Employee class as its Content. The DataTemplate could contain controls to show the values.

<Window.Resources>
    <local:Employee x:Key="emp2" ID="20" Name="Second Employee "></local:Employee>
    <DataTemplate DataType={x:Type local:Employee}">
        <StackPanel>
            <TextBlock Text={Binding ID} />
            <TextBlock Text={Binding Name} />
        </StackPanel>
    </DataTemplate>
</Window.Resources>
<StackPanel>
    <ContentControl Content="{StaticResource emp2}" />
</StackPanel>
