How do I clear a combobox?

Question

I have some combo-boxes that are set up as drop down lists, and the user can pick a number in them. I also have a Clear button that should clear the text from the combo boxes but I can't seem to get it. I've tried:

 //doesn't work  cboxHour.Text = ""; 

and

//doesn't work cboxHour.ResetText(); 

This seems like it should be so straight forward but I'm just not getting it.

Answer 1

Did you try cboxHour.Items.Clear()?

Answer 2

If you just want to clear the current selection, but leave all of the items in the list, you can use:

cboxHour.SelectedIndex = -1
