How to display items in Canvas through Binding

Set the ItemsPanel to a Canvas and bind the containers instead of the TextBlock in the DataTemplate

<ItemsControl ItemsSource="{Binding Path=ItemsToShowInCanvas}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <Canvas/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemContainerStyle>
        <Style TargetType="ContentPresenter">
            <Setter Property="Canvas.Left" Value="{Binding Left}"/>
            <Setter Property="Canvas.Top" Value="{Binding Top}"/>
        </Style>
    </ItemsControl.ItemContainerStyle>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Path=Text}" />
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>
