You can set using SelectedIndex  comboBox1 SelectedIndex  1    OR  SelectedItem  comboBox1 SelectedItem    your value         The latter won t throw an exception if the value is not available in the combobox  EDIT  If the value to be selected is not specific then you would be better off with this  comboBox1 SelectedIndex   comboBox1 Items Count - 1

Remember that collections in C  are zero-based  in other words  the first item in a collection is at position zero   If you have two items in your list  and you want to select the last item  use SelectedIndex   1

User · Answer

This means that your selectedindex is out of the range of the array of items in the combobox   The array of items in your combo box is zero-based  so if you have 2 items  it s item 0 and item 1
