my comboboxes is filling on dropdown i want if user dont select something in it and press somewhere or just close dropdown combobox value was null
Sorry for my english
if the combo box is opened then closed(for any reason) and the user did not select something, the combobox will have the same value it had before it was opened.
Note: If you are filling the combobox with values from a datasource and you want it to have a null value, then set the
selectedIndexof the combobox to -1
