Add items to comboBox in WPF

Question

When I have added a comboBox to the WPF window, how do I add items to the comboBox? Int the XAML code for the design or in NameOfWindow.xaml.cs file?

Answer 1

I think comboBox1.Items.Add("X"); will add string to ComboBox, instead of ComboBoxItem.

The right solution is

ComboBoxItem item = new ComboBoxItem();
item.Content = "A";
comboBox1.Items.Add(item);
