I have a form which has these fields:
ID, Degree 1, Degree 2.
The user choose from combobox the id and then write the degrees.But I want
like the user dont have the permission to write to the combobox an id which
is not already contained in combobox. ANd the form appear a message if he do
that that he cant.
How i show these message?and how i create it?
