I have this GridView wrapped in a Grid. When Full Screen, it looks good. But when I minimize it, I want the whole GridView to be centered within the Grid. In the below images (link provided), one of them is in full screen and it's ok. The other one is aligned to the left on minimizing. How can I Center them. The left and right padding is fine, but it looks ugly. Here is my GridView styles and panels.

<GridView.ItemContainerStyle>
    <Style TargetType="GridViewItem">
        <Setter Property="Margin" Value="10, 10, 10, 10"/>
    </Style>
</GridView.ItemContainerStyle>

<GridView.ItemsPanel>
    <ItemsPanelTemplate>
        <ItemsWrapGrid x:Name="MaxItemsWrapGrid"
                       MaximumRowsOrColumns="3"
                       Orientation="Horizontal"/>
        </ItemsPanelTemplate>
</GridView.ItemsPanel>

The GirdView Images can be found below.
