C# : ComboBox AutoComplete

[igalep132]

Hey,

I've a comboBox with some List Items (countries names)
I was wondering how can I force the user to select those countries which are Listed in the collection list only, without any opportunity to add his own item

Change the combobox style to that of only allows what is in it. It's an option on the property page.

It's not what you would think :-D
The property is called 'DropDownStyle'
Changing the value to 'DropDownList' will limit the control to what is in it's list (Making it behave like a listbox).

If you don't want to dissallow like that, there is also a method of checking to see if the selected index is not -1.
If you populate the combobox with values and have the auto-complete on, if someone types in something not in the list, the selected index will be -1, if they typed in something that IS in the list, the combo box automatically moves to select it and the selectedindex will have a >-1 value

DropDownStyle has to be DropDownList
