I want to refresh my combo box .
i have even used the combobox.refresh() syntax but it does nothing!
combobox.SelectedIndex = -1
If your combobox is set with the "DropDownList", then
use Combobox1.SelectedIndex = -1
I've experimenting, but it did not work
Please start a new thread and post the code that doesn't work so that we can offer suggestions.
then load your combobox again
ComboBoxguest.Items.Clear() 'clear combobox
guest()'i load again combobox from this methode
Try: .refresh(), then .items.clear(), then invalidate()
