I have a combobox that I want to be able to add items to the beginning of. For example, when you click it, you get 1,2,3 , but I want to be able to add an option, 0, so that when you click it you get 0,1,2,3.
Is this possible without rebuilding the combobox?
只需使用组合框的Items属性的Insert方法:
myComboBox.Items.Insert(0, "New item at top");
Yes, you can use the Insert()
method on the Items
property of your ComboBox
object.
var comboBox = new ComboBox();
comboBox.Items.Add("1");
comboBox.Items.Add("2");
comboBox.Items.Add("3");
comboBox.Items.Insert(0, "0");
