How to display data object in ListBox C#?

Question

I have function that fills ListBox:

private void fillWorkListBox()
{
    this.list = manager.works();
    this.listBox1.DisplayMember = "Название";
    this.listBox1.ValueMember = "ID";

    for (var i = 0; i < this.list.works.Count; i++)
    {
        string name = "№" + this.list.works[i].id + " - " + this.list.works[i].name;

        WorkModel work = new WorkModel();
        work.name = name;
        work.id = this.list.works[i].id;

        listBox1.Items.Add(work);

    }
}

Model is:

class WorkModel
{
    public string name { get; set; }
    public int id { get; set; }
}

When I have run project I see type of object model work in ListBox. Instead name and key as id.

How to fix it?

I guess that's because your WorkModel has neither a property called Название nor one called ID. It only has name and id. The names you give in DisplayMember and ValueMember must match properties in your model. — René Vogt

yes of course, what else did you intend? but I just checked: casing is not important, so Name and IDshould also work. — René Vogt

It works: ` this.listBox1.DisplayMember = "name"; this.listBox1.ValueMember = "id";` — Daniel

private void fillWorkListBox()
        {
            IList<WorkModel> managerWorks = new List<WorkModel>
            {
                new WorkModel {name="fooNameOne",id=1 },
                new WorkModel {name="fooNameTwo",id=2 }
            };

            listBox1.DisplayMember = "Название";
            listBox1.ValueMember = "ID";

            WorkModel workModel = new WorkModel();

            for (var i = 0; i < managerWorks.Count; i++)
            {
                string name = "№" + managerWorks[i].id + " - " + managerWorks[i].name;

                workModel.name = name;
                workModel.id = managerWorks[i].id;
                listBox1.Items.Add("Name:" + workModel.name + "Id:" + workModel.id.ToString());
            }
        }

Instead of adding work object directly to the list box.

Do something like below. If you want ID to be displayed, You can append ID too (You may need to convert to string before appending)

listBox1.Items.Add("Name: " + work.name + "Key: " + Convert.ToString(work.id));

I need to set also key as id. This case does not fit

Pavan Chandaka Over a year ago

Append key by adding as shown . listBox1.Items.Add("Name: " + work.name + "Key: " + Convert.ToString(work.id ) );
