ComboBox Index

Hi I found an interesting issue during my work. I am setting different SelectedIndex values to two ComboBoxes in my Form. But both the ComboBoxes have the same value which is set at the end.
Why this might be so?
My code is like this:

var list = new List<system.collections.dictionaryentry>();
list.Add(new System.Collections.DictionaryEntry("one", 1));
list.Add(new System.Collections.DictionaryEntry("two", 2));

comboBox1.DataSource = list;
comboBox1.DisplayMember = "Key";
comboBox1.ValueMember = "Value";
comboBox1.SelectedIndex = 0;

comboBox2.DataSource = list;
comboBox2.DisplayMember = "Key";
comboBox2.ValueMember = "Value";
comboBox2.SelectedIndex = 1;

Here at the end of the function, both comboBox1 and comboBox2 have SelectedIndex value as 1 instead of being 0 and 1 respectively.
Any idea? :)
