I'm dealing with the fact that when I clear items in a combobox programmatically, the text do not change and keep the last selected item.

How can I do it?

回答1:

Try

comboBox.SelectedIndex = -1;

Or

comboBox.Items.Clear();
comboBox.ResetText();

回答2:

Another way for combo boxes:

Populate

comboBox1.DataSource = new string[] { "", "bruce", "clark", "tony" };

Clear

comboBox1.DataSource = null;
