I have the following event right now
private void contactGrid_RightTapped(object sender, RightTappedRoutedEventArgs e)
{
if (contactGrid.SelectedIndex >= 0)
{
FrameworkElement senderElement = sender as FrameworkElement;
MenuFlyout menu = new MenuFlyout();
MenuFlyoutItem item1 = new MenuFlyoutItem() { Text = "Edit Contact" };
MenuFlyoutItem item2 = new MenuFlyoutItem() { Text = "Comfirm" };
MenuFlyoutSubItem item2a = new MenuFlyoutSubItem() { Text = "Remove Contact" };
item1.Click += new RoutedEventHandler(EditContactClicked);
item2.Click += new RoutedEventHandler(RemoveContactClicked);
item2a.Items.Add(item2);
menu.Items.Add(item1);
menu.Items.Add(item2a);
menu.ShowAt(senderElement, e.GetPosition(contactGrid));
}
}
This works fine and creates the right click context menu at the mouse pointer on top of a listbox item, but only if it has been selected first. What I can't figure out is how to get the RightTapped
event to select the item that was right tapped. I have yet to test this in tablet mode and I'm currently using a mouse to trigger the right tapped event (by right clicking).
Is the default behaviour of a long press (to trigger a right tap) in tablet mode such that it selects the item anyway?
As far as I understand, contactGrid
is your ListBox
? I guess you have any kind of List
or Collection
set as the ItemsSource
of the ListBox? Then you can set the SelectedItem
property in your right tapped-event like following:
First you need to modify the ItemTemplate, so that RightTapped belongs to a ListBoxItem:
<ListBox x:Name="ContactGrid">
<ListBox.ItemTemplate>
<DataTemplate>
<Border Background="Transparent" RightTapped="contactGridItem_RightTapped">
<TextBlock Text="{Binding}" />
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
And in code (I'm actually wondering that the Flyout is shown above the selectedItem and not above the whole ListBox):
private void contactGridItem_RightTapped(object sender, RightTappedRoutedEventArgs e)
{
FrameworkElement senderElement = sender as FrameworkElement;
// Now you can get the tapped Item from the DataContext and set is as selected
contactGrid.SelectedItem = senderElement.DataContext;
if (contactGrid.SelectedIndex >= 0)
{
MenuFlyout menu = new MenuFlyout();
MenuFlyoutItem item1 = new MenuFlyoutItem() { Text = "Edit Contact" };
MenuFlyoutItem item2 = new MenuFlyoutItem() { Text = "Comfirm" };
MenuFlyoutSubItem item2a = new MenuFlyoutSubItem() { Text = "Remove Contact" };
item1.Click += new RoutedEventHandler(EditContactClicked);
item2.Click += new RoutedEventHandler(RemoveContactClicked);
item2a.Items.Add(item2);
menu.Items.Add(item1);
menu.Items.Add(item2a);
menu.ShowAt(senderElement, e.GetPosition(contactGrid));
}
}
(not tested, but that's how I would solve it)
