[.NET SDK] Perform selection on ListBox and reload barcharts/combocharts data

Hello,

I'm fairly new to Qlik and I'm building a .NET application that connects to a Qlik sheet and is suppoused to extract underlying data from barcharts/combocharts. I'm able to pull the data from the charts via HyperCubePages however the sheet itself has several listbox objects that filter the data displayed on charts - want I want to achieve is to apply the filters (listbox selections) and retrieve the data from the charts.

var uri = new Uri("myQlikInstanceUri"); var location = Location.FromUri(uri); location.AsNtlmUserViaProxy(); using var hub = location.Hub(); var appIdentifier = hub.GetAppList().First(x => x.AppName = "MyAppName"); var appConnector = location.App(appIdentifier.AppId); var sheet = appConnector.GetSheets().First(x => x.Id == "mySheetGuid"); var listBox = sheet.GetChild("listBoxGuid") = as Listbox; // Retrieve listbox possible values foreach (var listboxItem = listbox.GetAllListObjectPagers()) { var data = listboxItem.GetAllData(); foreach (var dataItem in data) { // get possible listbox values } } // How to apply value selection to ListBox to apply filtering on barcharts/combocharts?

I'd be greatful if anybody had any experience with it and would like to share 🙂

The listbox is a visual object that represents a field. What you want to do is interact directly with the Field, not the Listbox. For example:

var field = appConnector.GetField("myfield"); field.Select("foo");
