Default Border is showing while using Gridview in windows phone uwp - windows

Question

I am displaying list of items with it's headers and content using gridview as shown below.
<Grid>
<GridView ItemsSource="{Binding Source={StaticResource src}}">
<GridView.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Background="#2a2621" Width="400" Height="35" Margin="-10,0,-10,0">
<TextBlock x:Name="atistType" Width="200"
Text="{Binding RegionalName}"
Foreground="White"
FontWeight="ExtraBold" FontSize="22" Margin="10,0,0,0"/>
<Image Margin="110,0,10,0"
Tag="{Binding RegionalName}"
Tapped="RedirectToImageListing"
Source="Assets\Right-arrow.png"
Height="25"></Image>
</StackPanel>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</GridView.GroupStyle>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid Orientation="Horizontal" MaximumRowsOrColumns="2"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.ItemTemplate>
<DataTemplate>
<Grid Margin="0,5,0,5" Tag="{Binding AlbumId}"
Tapped="RedirectToImageListOrGridView" >
<Grid>
<Image Width="{Binding ListingWidth}" Source="Assets/PlaceHolder.jpg"></Image>
<Border BorderThickness="1" BorderBrush="White">
<Image Width="{Binding ListingWidth}"
Source="{Binding SmallImage}"></Image>
</Border>
</Grid>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
I am able to show the data perfectly.
But, my concern is from somewhere a line is displaying like border.
You can check in the screenshot.
As shown in the screenshot, for the first image only a line is displaying like a border.
Is there a way to remove that.
I am not able to find from where the border is coming.
Thank you.

Try this
<GridView>
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="Margin" Value="0,0,4,4" />
<Setter Property="Background" Value="Transparent"/>
<Setter Property="TabNavigation" Value="Local"/>
<Setter Property="IsHoldingEnabled" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridViewItem">
<ContentPresenter />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GridView.ItemContainerStyle>
