ItemTap event

[Wayde]

Is there any way of getting the item that has been tapped? I need to find out which conversation item a user has selected, but I cannot find a way to get this to work.

Alternatively, is there a way to get a HyperLinkButton to fire an event from within the IncomingMessageTemplate or OutgoingMessageTemplate? I have tried this from within the DataTemplate, but my events do not fire when clicked on. For instance, if a user were to send a link in a message, I want to be able to click this.

Hi Wayde,

Thanks for writing.
Currently, there are two very easy ways to get to the selected item:
1. Manually search for the selected item on tap:

private void OnConversationViewTap(object sender, System.Windows.Input.GestureEventArgs e)
{
    RadDataBoundListBoxItem listBoxItem = ElementTreeHelper.FindVisualDescendant<RadDataBoundListBoxItem>(sender as DependencyObject, (child) =>
    {
        RadDataBoundListBoxItem item = child as RadDataBoundListBoxItem;
        if (item == null)
        {
            return false;
        }

        Rect layoutSlot = new Rect(new Point(), item.RenderSize);
        Point tapLocation = e.GetPosition(item);

        return layoutSlot.Contains(tapLocation);
    });

    if (listBoxItem == null)
    {
        return;
    }

    object message = listBoxItem.Content;
}

2. Extend RadConversationView, expose a SelectedItem property and then use the new conversation view.

public class CustomConversationView : RadConversationView
{
    private RadDataBoundListBox listBox;

    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();
        this.listBox = this.GetTemplatePart<RadDataBoundListBox>("PART_ListBox");
    }

    public object SelectedItem
    {
        get
        {
            if (this.listBox == null)
            {
                return null;
            }

            return this.listBox.SelectedItem;
        }

        set
        {
            if (this.listBox == null)
            {
                return;
            }

            this.listBox.SelectedItem = value;
        }
    }
}

You can get the HyperLinkButton event by using commands. Every button has a Command property that you can set to your own command in which you can whatever is necessary.

Thanks for the feedback, we'll consider exposing an ItemTapped event or ItemSelected in a future release.
