Problem: GridView when selected, creates a <GridView/> tag that does not update with changes to data binding, making it impossible to display a GridView of Items from ItemSource without manually modifying .xaml file.

• GridView tag in .xaml will default to <Gridview/> when the View is changed from "None" with both new ListView items and ListView items that were originally GridView (and working) then changed to "None" (tested in sample code provided by Sfernandez).
• The functioning sample of the GridView tag will not update header bindings when ItemSource of ListView binding was unbound and rebound
• The functioning sample of the GridView tag will not update header bindings when ItemSource of the ListView data structure changed to add new data columns, including when unbound and rebound.
• Selecting the GridView View property within source project (not the sample) would only ever produce <GridView/> in .MainPage.xaml,
• Listview templates created with GridView View property selected would not include GridViewRowHeaderPresenter, and when added manually to template, would not show column headers as the collection was empty in the <GridView/> tag.

Originally posted about it on Studio Forum:

I found out that when I rebuilt the exact same data-template from scratch in my other project, the listview, unfortunately never displayed as a GridView, even though the option is selected. I think there is something funky going on between the studio assignment of gridview and the instance of it.

Looking at the XAML for the default GridView configuration from your project:

<ListView Height="300" HorizontalAlignment="Center" VerticalAlignment="Center" Width="500" ItemsSource="{Binding Path=Table}">
      <ListView.View>
        <GridView>
          <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}" Width="150"/>
          <GridViewColumn DisplayMemberBinding="{Binding Path=Format}" Header="Format" Width="80"/>
          <GridViewColumn DisplayMemberBinding="{Binding Path=Count}" Header="Count" Width="80"/>
        </GridView>
      </ListView.View>
    </ListView>

Vs the one in my project when I create a ListView and set it to GridView via the View Property I get the following code:

<ListView Height="100" ItemsSource="{Binding Path=Table}">
                  <ListView.View>
                    <GridView/>
                  </ListView.View>
                </ListView>

The other thing I noticed is when I go to your original project and change the ListView View type to "none", and then back to "GridView" via the properties panel the XAML changes to produce the same <GridView/> that produces no GridView column binding:

<ListView Height="300" HorizontalAlignment="Center" VerticalAlignment="Center" Width="500" ItemsSource="{Binding Path=Table}">
      <ListView.View>
        <GridView/>
      </ListView.View>
    </ListView>

I tested adding custom templates with headers, and more. Unforunately the only way I could get the GridView to behave as described in my source project was replacing the <GridView/> with the functioning sample code directly in the MainPage.xaml . Is this working as intended or have I encountered a bug?
