ListBox and ComboBox

[Tamer_Ahmed]

hi every one ListBox and comboBox Controls implement the same interfaces ICollection and IList so what's the different between them is it just the way of viewing the data or there's another different

Just the way the data is presented, a combobox takes up less screen area until you select the drop down. Also combo boxes can allow you to type values not contained in the list itself but a listbox always restricts you to the values provided.

hi Thanks for answering me i didn't understand this part

It's because you can't type a value directly in a listbox but can only select value(s) from the list. On the other hand, you can type an arbitrary value in a combobox, provided its DropDownStyle is not set to DropDownList.
