a lot of people have answered the question of how to bind an enum to a combo box in WinForms. Its like this:
comboBox1.DataSource = Enum.GetValues(typeof(MyE
The code
comboBox1.SelectedItem = MyEnum.Something;
is ok, the problem must reside in the DataBinding. DataBinding assignments occur after the constructor, mainly the first time the combobox is shown. Try to set the value in the Load event. For example, add this code:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
comboBox1.SelectedItem = MyEnum.Something;
}
And check if it works.
