Hi, Can anyone point me to some example code that does the same behaviour as the Catalog, Portal, Living Atlas. When you hover over an item you get a nice popup floating inline with item which fades in and out.  The screenshot below shows what I mean:   ... View more

I have an ESRI control, SearchTextBox on my dockpane which I intend to show a suggested list of known authors in autocomplete dropdown that appears underneath the control - this is inbuilt functionality. You have to populate the SuggestionSource with an ObservableCollection of type objects. In my case I am passing a list of strings (after the user types at least 2 letters). I assign my list of strings to ObservableCollection<object> AuthorList which is bound in XAML:   <controls:SearchTextBox x:Name="AuthorTextBox" SuggestionListMax="15" SuggestionSource="{Binding AuthorList}" ShowMagnifier="False" InfoText="Author" SearchMode="Manual" TextChanged="AuthorTextBox_OnTextChanged"> </controls:SearchTextBox>   As you can see this works to some extent (see below) - but it does not populate on every key press - it is very intermittent - even if you wait 1 minute! between each key press - sometimes nothing populates, then you can press delete and lose focus and click back, then add some letters and it populates, but it is very erratic in behaviour and this is very frustrating for me. So I am typing "Jones" - and I debug and I can clearly see that the list has been cleared and it is about to accept 15 new entries,   however this seems to be ignored. When I go back to the application the control looks like this:     Here is my code on the text changed event - it is retrieving a list of 15 authors in sub second speed, it is very fast. private async void AuthorTextBox_OnTextChanged(object sender, TextChangedEventArgs e) { if (AuthorTextBox.Text.Length > 2) { try { UriBuilder uriBuilder = new UriBuilder { Scheme = "https", Host = "localhost", Path = "service/AuthorBasic/1", Port = 7269, Query = $"name={AuthorTextBox.Text}" }; var response = await CitationSearchVM.Client.GetAsync(uriBuilder.Uri); if (response.IsSuccessStatusCode == false) { Log.Error("FAIL: " + response.StatusCode); } else { string jsonText = await response.Content.ReadAsStringAsync(); AuthorBasicResponse authorResponse = JsonConvert.DeserializeObject<AuthorBasicResponse>(jsonText); Module1.CitationSearchVM.AuthorList.Clear(); Module1.CitationSearchVM.AuthorList.AddRange(authorResponse.Authors); } } catch (Exception ex) { Log.Error(ex); } } } I don't know whether its some race condition or something I must be subtlety doing wrong. If anyone can help it would be much appreciated.                     ... View more

1. After creating graphics programmatically - the last one created has these adjustment handles left on them - is there anyway to stop this from happening?    2. Also you can see each graphic being made in turn - is there a more elegant way for these to be shown to the user - preferably all at once.     ... View more

How do you query a feature service with many hundreds of points? I want a return a value from a field (let's call in "COUNTRY_NAME") that returns a country name (surprisingly!) for each point, and that's really important. I need a value for each point, 1 for 1. I have tried sending a multipoint query but it breaks (probably URL length). Even when I cut down the amount of points - if it finds values that are the same it seems to coalesce them all into one - very annoying and not useful. Here is a screenshot of what I have done for multipoint queries.  Any help or pointers would be much appreciated as I am still finding my way with all this stuff.     ... View more
