Make combobox readonly

[Guest]

I have a combobox which contains the different departments at my work place.
However, if the user types another name into the combobox, it is accepted. I
wish to allow only the names already associated with the control. Also, how
can I set the control so that the user can type, for example, the letter "M"
and it takes them to the first instance, which is manager? Visual Studio has
no readonly property in the properties window, and doesn't accept it in code.

Any help would be most appreciated.

hi,

Set the droupdown property of combo box to DroupDownList
