    UserControl cannot bind to its own properties?

    Basicaly I have an user control that defines a string DependenyProperty
    Caption. In the xaml i have the following code:

    <UserControl x:Class="PlasmaBox.TrackHeaderView"
    xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
    xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"
    Name="xyz"
    >

    <UserControl.FixedTemplate>
    <Grid>
    <Grid.ColumnDefinitions>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="50"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
    <RowDefinition/>
    <RowDefinition/>
    </Grid.RowDefinitions>



    <Button Grid.Column="1" Grid.Row="0"/>
    <Button Grid.Column="1" Grid.Row="1"/>
    <TextBlock
    Grid.Column="0"
    Grid.RowSpan="2"
    VerticalAlignment="Center"
    Text="{Binding ElementName=xyz,Path=Caption}"/>
    </Grid>
    </UserControl.FixedTemplate>
    </UserControl>

    The Text comes up empty. I've tried al variations of binding with no
    luck at all. Is this broken in the December CTP - (if yes, is there a
    workaround), or am I doing something wrong?

    Thanx,
    Lubomir

    I'm guessing the name xyz can't be found in the context you used it,
    although it's too late in the day for me to be sure <g>.

    Hi Lubo - I tried to solve your problem but without any success. I found a
    couple of links to people solving very simmilar-sounding problems. Maybe they
    can provide you with some insights.
