GridView Drop Event not firing

Hello Michael,

You can subscribe ListView.DragItemsStarting event where you can set the drag data.

Give this a try:

        <StackPanel>
            <ListView x:Name="listViewDataItems" CanDragItems="True" DragItemsStarting="listViewDataItems_DragItemsStarting_1"  SelectionMode="Multiple" ItemsSource="{Binding}">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding Path=Text}"/>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
            <Border AllowDrop="True" Drop="Border_Drop_1"  Background="Green">
                <TextBlock Name="tb" Height="100"/>
            </Border>

        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            listViewDataItems.DataContext = new ObservableCollection<MItem> { 
                new MItem(){Text="A"},
                new MItem(){Text="B"},
                new MItem(){Text="C"},
                new MItem(){Text="D"}
            };
        }
        class MItem
        {
            public string Text { get; set; }
        }
        private async void Border_Drop_1(object sender, DragEventArgs e)
        {
            tb.Text = await e.Data.GetView().GetTextAsync();
        }
        private void listViewDataItems_DragItemsStarting_1(object sender, DragItemsStartingEventArgs e)
        {
            e.Data.SetText(((MItem)e.Items[0]).Text);

I hope this helps,

James
