Dynamic Tooltip WPF

Firstly; I am very very new to WPF - so please excuse me if this sounds ridiculous.
I need to have dynamic tool tips in my application. The data in the tooltips can change so I can't just hard code them; the contents of the tooltips will probably be stored in a database (or a wiki)
Is there a way in WPF that I can perhaps bind my tooltip to an underlying business class that can go away and return the correct tool tip?

Any help would be very much appreciated
Thanks in advance

<ToolTip x:Key=toolTipTextBoxBinding
         DataContext={Binding Path=yourclassobectproperty,
           RelativeSource={Staticresource yourclassobject}}>
your class property should change dynamically the way you want.

There are a number of errors coming up when I attempt the above example... I am not sure if this is due to a schema that I am using? or just how I am attempting to bind the tooltip..
I have attached the xaml code and the basic outline of the underlying class that I want to attach to.
I want the tooltip for the name to show the current name and likewise for the age

Any help on this would be very much appreciated
Thanks in advance
This is the xaml file...
<Window x:Class="WpfApplication1.Window2"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window2" Height="110" Width="270">
 
    <Grid ShowGridLines="True">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="200" />
        </Grid.ColumnDefinitions>
        <Label Grid.Row="0" Grid.Column="0" Content="Name:" />
        <Label Grid.Row="1" Grid.Column="0" Content="Age:" />
 
        <TextBox Grid.Row="0" Grid.Column="1" Margin="3" Name="txtName" />
        <TextBox Grid.Row="1" Grid.Column="1" Margin="3" Name="txtAge" />
        <Button Grid.Row="2" Grid.Column="1" Name="incrementAgeButton" Click="incrementAge_Click">Increment Age</Button>
    </Grid>
</Window>
 
and this is the shape of the class
public class Person
{
   public string Name
   public int Age
}

Open in new window

If you want to bind Name and age to the relevant textbox tooltip, you need to declare them as properties. also please show how you put tooltip code, and what errors you are getting.
