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,

Krasimir
