Hi

try this code:

this code simply do the following:

1- graps all Cad Instances in your Project

2- create a new ListViewItem and assign an item text "Visible to user" the name of the instance.

3- give the item name the Id of the element so we can use it as a reference later.

4- now if you checked any element it will give a text message to showing the id name.

5- last statment is how you can get the element from you projecty from the ID.

I hope that helps.

        public Frm_Importins()
        {
            InitializeComponent();
            listView1.CheckBoxes = true;

            FilteredElementCollector filcol = new FilteredElementCollector(m_doc).OfClass(typeof(ImportInstance));
            foreach (ImportInstance imps in filcol)
            {
                
                ListViewItem listit = new ListViewItem(imps.get_Parameter(BuiltInParameter.IMPORT_SYMBOL_NAME).AsString());
                listit.Name = imps.Id.ToString();
                listView1.Items.Add(listit);
            }
            
        }

        private void listView1_ItemChecked(object sender, ItemCheckedEventArgs e)
        {
            if (e.Item.Checked)
            {
                MessageBox.Show("You selected Element of ID " + e.Item.Name);

                //get a handle of Revit Element 
                Element ele = m_doc.GetElement(new ElementId(int.Parse(e.Item.Name)));

            }
        }
