I have some question on customizing Properties page.
In a document library when I select a document and choose Edit
Properties, it will display a properties page wherein I can select
the content type I want and it will display the columns associated
with that content type.
Our requirement is, for example, if the fields in the properties
page are:
1. Employee ID
2. First Name
3. Last Name

What we want is for user to enter just the Employee ID and a custom
code will lookup the Employee ID to a SQL table and return and
display the First Name and Last Name on the screen when user get out
of that Employee ID field. Another requirement is to make the First
Name and Last Name read-only field.
Is there any event that can trapped this. Some kind of a client side
trapping (kind of javascript events).
