You should set the ReorderMode property to enable reordering of gridviewitems. And also in the itemtemplate of the gridview you are creating a gridviewitem inside the gridviewitemtemplate.
Have you data template as below:
<GridView.ItemTemplate>
<DataTemplate>
<Border Margin="10,20,0,0" Height="70" Width="100" BorderBrush="LightGray" BorderThickness="1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="0.3*"/>
<RowDefinition Height="0.7*"/>
</Grid.RowDefinitions>
<TextBlock Margin="1" Text="Hi" Grid.Row="0" Foreground="#FF25A0DA" FontSize="10"/>
<TextBlock Margin="1" Text="Forum" Grid.Row="1" Foreground="Gray" TextWrapping="Wrap" FontSize="10"/>
</Grid>
</Border>
</DataTemplate>
</GridView.ItemTemplate>
