ComboBox.SelectedValue not working

What is wrong with this code?

myComboBox.Items.Clear();
myComboBox.Items.AddRange(new string[]{"one","two"});
myComboBox.SelectedValue = "one";

It is showing up with nothing selected.

Solution

  • If you populate the combobox like this:

    myComboBox.Items.AddRange(new string[]{"one","two"});

    You must use the ComboBox.SelectedItem or the ComboBox.SelectedIndex property to set/get the selected item:

    myComboBox.SelectedItem = "one"; //or
myComboBox.SelectedIndex = 0;

    The ComboBox.SelectedValue property is inherited from ListControl and must be used ONLY when:

    • the control is bound to a DataSource
    • and ValueMember and DisplayMember properties are definied.
