Associate value with item in combobox

Hi,

in ASP .Net, I can associate a value with and item in a dropdown list, for
example when binding to a list of employees, I can store the employeeid as a
value associated with each name in in the list so I can use this later when
retrieving data from my database.

I am now trying to develop a Windows forms app (.Net 2.0) and can find how
to do this when using a combobox set to the dropdownlist style (assume this
is the control I should us). When adding items manually, I only get a list
of strings to add but nowhere to associate a value.

Can anyone please shed som light on how to do this in Windows forms ?

Thank you

Niclas

Hi Niclas,

You can actually add objects (instances of classes) to the combobox, not
just strings, and the ToString() method will be used to show a text for the
object. The ComboBox has properties to retrieve the selected object, that
you can cast back to your class and retrieve the full object.
