To start with, specify what do you mean by ComboBox. Which one? Full type name, please. Is it System.Windows.Forms.ComboBox? Anything else?

Where are you getting the SelectedIndex value? I don't see anything like that here. Just that you're setting the DataSource to sheetname only.

Try the following -

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
    ComboBox cmb = (ComboBox)sender;
    int selectedIndex = cmb.SelectedIndex;
    int selectedValue = (int)cmb.SelectedValue;

    ComboboxItem itm= (ComboboxItem)cmb.SelectedItem;
}
