wp7 ListBox SelectionChanged Text Color

1
votes

The default behaviour for a ListBox used in a WP7 application is for the selected item to be highlighted in the PhoneAccentBrush. I am finding that with a ListBox that when I handle the SelectionChanged event (sets a property and closes popup that contains the ListBox) I never see the text color change to the PhoneAccentBrush - so the user never gets any feedback that they have selected the correct item. Is there a way to work around this and give the user feedback (even though it will only be momentary) as to which item they have selected.

I'm not very sure what you mean, the listBox.selectedItem is highlighted. Maybe you can try to have the item within the listBox datatemplate. - Nghia Nguyen
If you close the "popup that contains the listbox" when you select an item in the listbox what would be left to show the selection anyway? - Matt Lacey
With the delayed SelectionChaged (my answer below) the user has a visual feedback. It is a short instant, but long enough to make an impression on the user. - Jan Slodicka

Delay your handling of SelectionChanged event, for example

void list_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    Dispatcher.BeginInvoke(action);
}

void action()
{
    // put your code here
}

Take the Silverlight toolkit and add a tilt effect (push animation like in other apps).

Reference the toolkit in your project and add the namespace to use the toolkit: 

<phone:PhoneApplicationPage 
    ...
    xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit">

In your datatemplate add the attached property IsTiltEnabled:

<DataTemplate>
    <Grid toolkit:TiltEffect.IsTiltEnabled="True">
        ...
    </Grid>
</DataTemplate>
