WPF DataTemplate Issue

I have a WPF application that uses data templates to bind and format a ListView control. The data templates are also supposed to control the text alignment in the cells of the ListView. Here is an example of one template:

<DataTemplate x:Key="CellID">
     <TextBlock HorizontalAlignment="Center" 
               Text="{Binding Path=ID}"/>
</DataTemplate>

Open in new window


The problem I am having is that the "center" is not applied, the text is left justified in the textblock, however the binding works correctly and the correct data is displayed.

This template is used like this:

<ListView x:Name="lstCues" Background="{x:Null}" Foreground="#FFD3F506" ItemsSource="{Binding Mode=OneWay}">
	<ListView.View>
		<GridView>
			<GridViewColumn Width="50" Header="Cue ID" CellTemplate="{StaticResource CellID}" />
			<GridViewColumn Width="200" Header="Name" CellTemplate="{StaticResource CellName}"/>
			<GridViewColumn Width="400" Header="Filename" CellTemplate="{StaticResource CellFilename}"/>
		</GridView>
	</ListView.View>
</ListView>

Anyone have ideas why this is not working? I am pretty sure this is how I have done this in the past.

Thanks,
Sid.

Thank you for the suggestion. I edited my code but get the same result, the text is not centered:

		<DataTemplate x:Key="CellID">
			<Border HorizontalAlignment="Stretch">
    			<TextBlock HorizontalAlignment="Center" Text="{Binding Path=ID}">
    				<TextBlock.Foreground>
    					<Binding Converter="{StaticResource IDDisplay}" />
					</TextBlock.Foreground>
				</TextBlock> 
			</Border>
		</DataTemplate>

it seems that your itempanel is not being centered, so you may try in addition, at ListView level (not at template level):

<ListView HorizontalContentAlignment="Stretch"  ......

I added that but no change:

<ListView x:Name="lstCues" HorizontalAlignment="Stretch" Background="{x:Null}" ItemsSource="{Binding Mode=OneWay}" BorderBrush="{x:Null}" Grid.Row="1">

It is HorizontalContentAlignment and not HorizontalAlignment

<ListView x:Name="lstCues" HorizontalContentAlignment="Stretch" Background="{x:Null}" ItemsSource="{Binding Mode=OneWay}" BorderBrush="{x:Null}" Grid.Row="1">
