Add items to ComboBox at runtime?

Royce Roy 3143 10 Apr 2014

I am trying to add items to a ComboBox (say Name="labelComboBox") at runtime when I pressed an add button (say with Name="add2labels" Click="add2labels_Click"). But the ComboBox cannot show the values I newly added. What did I miss?

The following is the event handler for the add button:

private List<String> labels = new List<String>();
... ...
private void add2labels_Click(object sender, RoutedEventArgs e)
{
   
labels.Add("new value");
    labelComboBox.ItemsSource = labels;
}

P.S. I am pretty sure the values were added to List<String> labels correctly (its count did increase each time).

Hi Royce,

Combobox has a display and value member to add values to combo-box you need to specify both.

Try this

ComboboxItem item = new ComboboxItem();
item.Text = "new value";
item.Value = 12;
labels.Items.Add(item);
