How can I delete all the items in combo box?

Question

I have a ComboBox control with the DropDownStyle properties set to DropDownList. I want to replace the list of items with some new items at some points in the form but it concatenates the new items with the old items. How can I delete the old items and place new items in the combo box?

I am trying something like that:

        this.selectAttribute.Items.AddRange(new object[] {
            "Airport_Name", //New items
            "City",
            "Country"});

Answer 1

You could try clearing the items first:

this.selectAttribute.Items.Clear();
