Hello Kumaran,

Thank you for your post. I have been reading through it and I can suggest handling the SizeChanged event of the XamTile in order to determine when the size of the tiles is changed. To do that you can create a style without key and add it to the Resources of your XamTileManager. Here is an example on how you can implement this approach:

Xaml:

...
<ig:XamTileManager.Resources>
    <ig:TileConstraints x:Key="tileConst"></ig:TileConstraints>
    <Style TargetType="{x:Type ig:XamTile}">
        <EventSetter Event="SizeChanged" Handler="Tile_SizeChaged"/>
    </Style>
</ig:XamTileManager.Resources>
...

C#:

private void Tile_SizeChaged(object sender, SizeChangedEventArgs e)
{
    //Implement your logic here.
}

Please let me know if you need any further assistance on the matter.

Sincerely,

In this way you will have a better control over the tiles arrangement, and the tiles proportions. Note that you have to use property ExplicitLayoutTileSizeBehavior to define how this layout will be rearranged after you resize a tile.

Please, refer to the documentation for XamTileManager to find more about different layouts for normal mode. 

I'm a little bit confused about what you are trying to achieve. If your goal is the above layout, then I can try to provide you a simple sample. But you can play with these properties, check the documentation, and find some solution on your own.

I'm looking forward your replay.

Thank you,

Olga G.
