I know with a combobox you type text in, and it looks for the text that is in an item in the DropDownList.  I am trying to allow a user to type text into it and if the text isn't in the combobox  list items, it can then go to an event in codebehind like a general textbox control.
For example, if I have a combobox named cbxFullName
I know that I have an event cbxFullName.selectedIndexChanged.
Is there a way to have an event for the textbox component such as:  cbxFullName.TextChanged
