Yes, you can. You need a DataTemplateSelector . You can select an appropriate template for the selected object in the grid/list.

Sample for selector:

class TemplateSelectorMyPage : DataTemplateSelector
    {
        public DataTemplate NormalIconTemplate { get; set; }
        public DataTemplate BigIconTemplate { get; set; }

        protected override DataTemplate SelectTemplateCore( object item, DependencyObject container )
        {
            var uiElement = container as UIElement;
            if( uiElement == null )
            {
                return base.SelectTemplateCore( item, container );
            }

            if ( item is BigIconItem )
            {
                return BigIconTemplate;
            }
            else if ( item is NormalIconItem )
            {
                return NormalIconTemplate;
            }
            return base.SelectTemplateCore( item, container );
        }

In the XAML:

<Page.Resources>
    <local:TemplateSelectorMyPage  x:Key="mySelector"
        BigIconTemplate="{StaticResource myBigIconTemplate}"
        NormalIconTemplate="{StaticResource myNormalIconTemplate}">
    </local:TemplateSelectorBusinessPage>
</Page.Resources>

In the Grid XAML:

<GridView           
            x:Name="itemGridView"
            ItemTemplateSelector="{StaticResource mySelector}"
