Hi,
Could you send me a sample code - how and when you create/apply  the template?
Regards,

Thank you for reply. 

This works fine when templates already exist in UserControl.Resources. I need to build template manually using StringBuilder and XamlReader, because in each different moment I don't know anything about structure of incoming data. And in this case I get what I told you about - image won't stretch correctly.

UPD: Looks like ContentPresenter in my template cannot correctly show vertical alignment. When I set VerticalAlignment to Center, Top or Bottom, it shows everything as intended. But Stretch won't work in this case.

Hi,
Yes, probably the post is about TilePane, but I cannot reproduce this issue.
I created a small sample based on your TilePane style and I’m using a data template that shows a picture and text. The ItemsSource is bound to a List <MyPicture>.
The pictures are created from the Waterfall.jpg Windows Vista sample picture  (C:\Users\Public\Pictures\Sample Pictures) but I changed the size of the second image.
XAML
<igTV:XamWebTileView x:Name="tv2" Grid.Row="1" Loaded="tv2_Loaded"
               TilePaneContainerStyle="{StaticResource CustomTilePaneStyle}">
  <igTV:XamWebTileView.TilePaneContentTemplate>
    <DataTemplate>
      <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <TextBlock Text="{Binding Text}" HorizontalAlignment="Center"/>
        <Border Grid.Row="1" BorderBrush="Black"
                                         BorderThickness="1" Padding="5" Margin="2">
          <Image Source="{Binding Image}" Stretch="Uniform" />
        </Border>
      </Grid>
    </DataTemplate>
  </igTV:XamWebTileView.TilePaneContentTemplate>
</igTV:XamWebTileView>
C#
private void tv2_Loaded(object sender, RoutedEventArgs e)
{
  List<MyPicture> pictures = new List<MyPicture>();
  pictures.Add(new MyPicture("W=1024, H=768", "W1024-768.jpg"));
  pictures.Add(new MyPicture("W=433, H=767", "W433-767.jpg"));
  tv2.ItemsSource = pictures;
}
public class MyPicture
{
  private string _imagePath;
  public MyPicture(string text, string imagePath)
  {
    _imagePath = imagePath;
    Text = text;
  }
  public string Text { get; set; }
  public ImageSource Image
  {
    get
    {
      string path = string.Format("{0}", _imagePath);
      Uri uri = new Uri(path, UriKind.Relative); 
      BitmapImage bi = new BitmapImage(uri);
      bi.CreateOptions = BitmapCreateOptions.IgnoreImageCache;
      return bi;
    }
  }
}
I don’t see anything wrong when I run this sample. Is there anything else?

Looks like he means TilePane. I have a similar problem. I got a grid with 2 rows. 1st row contains text and 2nd contains a picture. When picture has Landscape orientation, it stretches to tile width and I can see the whole image. In case of Portrait it also stretches to tile width but its bottom goes outside a tile. 

I have put Stretch attribute everywhere I can :) but everything still goes wrong. What should I do to keep image within tile borders? BTW, I put custom template to ToggeButton.Content. Below is TilePane's style

<Style x:Key="CustomTilePaneStyle" TargetType="igTileView:TilePane">

        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>

        <Setter Property="VerticalContentAlignment" Value="Top"/>
