Answer 1

You need to subscride second combobox on the SelectedIndexChanged event of the first combobox and change value when event triggers. Also you need to make sure that both combobox have several items or you will need to add missing items to second combobox dynamically.

Event handler example:

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        object selectedValue = this.comboBox1.SelectedValue;
        this.comboBox2.SelectedValue = selectedValue;
    }
