I have a databound ComboBox on my form. Is there any way that I can make the first field blank.

I can do this with a DropDownList in the HTML part of .Net but is there a way to do it for a ComboBox?

Thanks

ComboBox1.SelectedValue = -1

didn't work for me but this did:

ComboBox1.SelectedIndex = -1

I would have though -1 would have been an invalid index value, but obviously not.
