UWP ListView ItemClick

Question

I have defined ItemClick event handler for a ListView. The event handler is called, but when I click the ListViewItem for the first time SelectedItem of the ListView is null and SelectedIndex is -1. But I want to retrieve SelectedItem also on the first click when nothing is selected in the ListView. Is there another solution? Thanks.

Answer 1

As miskohut pointed out you can use ItemClickEventArgs, here is an example

        private void listView_ItemClick(object sender, ItemClickEventArgs e)
        {
           MyItemModel item = (MyItemModel)e.ClickedItem;
           //TODO:
        }

Answer 2

The answer is an easy one.

`ItemClickEventArgs`

contains attribute ClickedItem which is type of type DataContext of ListView.

Answer 3

More appropriately for the click event, get the clicked item index. For example,

  private void Column_ItemClick(object sender, ItemClickEventArgs e)
  {
     ListView listView = (ListView)sender;
     Tile clickedMenuItem = (Tile)e.ClickedItem; // Typecast the clicked menu item back to the content type of each list view item

     // Key line is here:
     int itemNumber = listView.Items.IndexOf(clickedMenuItem);
  }

In the above on click event of the listView.ItemClick += Column_ItemClick event, the itemNumber integer is the index of the clicked list view item.

This solution avoids the -1 index response for a selected item, because the on click event that selects an item happens only after the second click of the menu.
