System.NotimplementedException error

[A_S_E_]

Hello there,

If anyone has any idea why is my code failing even though after successful build i Visual Studio itself. While implementing in Revit i Get the following error. It works fine with TaskDialog (commented) but not TestWindow.

Thanks for helping.

the code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;
using System.Collections.ObjectModel;
using System.Xml.Linq;
using System.Windows.Media.Imaging;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI;
using Autodesk.Revit.ApplicationServices;

namespace ClassLibrary1
{

[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
public class Class2 : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{

UIApplication uiapp = commandData.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Application app = uiapp.Application;
Document doc = uidoc.Document;

//var components = uidoc.Selection.GetElementIds();

ICollection<ElementId> components = uidoc.Selection.GetElementIds();

TestWindow testWindow = new TestWindow(components);
testWindow.ShowDialog("Message",components.Count.ToString());
//TaskDialog.Show("Message", components.Count.ToString());
testWindow.Show();

//TaskDialog.Show("Revit", "Hello World");

return Result.Succeeded;
}
}

}

A snip from the code in Visual Studio.

It looks like you implemented one of the window events, but left it unchanged

    TestWindow testWindow = new TestWindow();
    testWindow.Closed += TestWindow_Closed;

private void TtestWindow(object sender, EventArgs e)
{
    throw new NotImplementedException();
}

HI @A_S_E_ 

What is Test Window, its a Event? or Winform ? Can you explain in detail

HI @A_S_E_ 

   You have link Revit Context With the WPF, Kindly check the Below Image and Code for Reference

Reference Code (UI Back end)

 public partial class TestWindow : Window
    {
        public TestWindow(List<ElementId> ids, double count)
        {
            InitializeComponent();

            //List of Element to UI
            foreach(ElementId id in ids)
            {
                listBox.Items.Add(id.IntegerValue.ToString()); //List Box
            }

            //Add Count to UI
            countLabel.Content = count.ToString(); //Label

        }
    }

Reference Code (Revit Execute)

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIApplication uiapp = commandData.Application;
            UIDocument uidoc = uiapp.ActiveUIDocument;
            Application app = uiapp.Application;
            Document doc = uidoc.Document;


            ICollection<ElementId> components = uidoc.Selection.GetElementIds();

            TestWindow testWindow = new TestWindow(components.ToList(), components.Count);
            testWindow.ShowDialog();


            //TaskDialog.Show("Revit", "Hello World");

            return Result.Succeeded;

        }

Hope this will helps 🙂
