WPF Simple Binding to an objects property

Question

Im having some problems with binding in wpf/xaml. Have this simple file:

<Window x:Class="test.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Grid>
        <TextBlock Height="21" Foreground="Black" Margin="74,98,84,0" Name="textBlock1" VerticalAlignment="Top" Text="{Binding MyText}" />
    </Grid>
</Window>

Where i want to bind the content of the textblock to my property "MyText". My code looks like this:

 public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
        }

        public string MyText
        {
            get { return "This is a test"; }
        }
    }

All in all very simple, but when i start the textblock has no content - howcome?

UPDATE: I dont even get a breakpoint at the property – H4mm3rHead Sep 22 '09 at 20:00 — H4mm3rHead, Sep 22 '09 at 20:00

you need an element name in your binding:

<Window ... x:Name="ThisWindow"...>

        <TextBlock ... Text="{Binding MyText, ElementName=ThisWindow}" />

If I'm remembering my WPF binding syntax correctly, I believe your binding expression should read Text="{Binding Path=MyText}"

Tried that, no luck, still blank... ...Text="{Binding Path=MyText}" /> – H4mm3rHead Sep 22 '09 at 19:59
Tried source, just rendered the text "MyText" which is the name of the property... Edit: the solution with a name in binding worked – H4mm3rHead Sep 22 '09 at 20:09
Thanks for the refresher, it's been a while since I studied WPF :) – jturinetti Sep 22 '09 at 20:34

There are a number of ways to accomplish this. Probably the easiest for something as simple as this form is:

public Window1()
{
    InitializeComponent();
    this.DataContext = this;
}
