I am a novice in Xamarin and C#. I am trying to get the key and the value of an Item that I select in a listview.
Here is my code to get my listview, this work fine cause I get a list of items:
//search on the list view
private async Task SearchMyFriendAsync(object sender, TextChangedEventArgs e)
{
string keyword = SearchFriend.Text;
Dictionary<string, string> words = await usermanager.GetUserList(keyword);
FriendsListView.ItemsSource = words;
}
When I select an item, I get an error; here is the code :
public async void OnSelectedFriendDescript(object obj, ItemTappedEventArgs args)
{
var FriendName = (KeyValuePair<string, string>)args.Item;
}
And here is the error :
Unhandled Exception:
System.NullReferenceException: Object reference not set to an instance of an object.
Here is a screenshot:
