This may or may not be possible but I'm trying my best to find out, I'm a complete novice when it comes to ASP.At the moment I have drafted a basic html page. This page contains a drop down list and several tables all hidden by javascript and then displayed based on the drop down selection (onchange event)I'm trying to convert this into an asp page so that I can dynamically populate the drop down from a table (this will be a list of names)and then based on the drop down selection (onchange does not necessarily have to be used, could maybe use a submit button) will populate a table below the input box with all the information for that name, in many cases this would be multiple rows.
How would I re-code the datagrid below so it displays as a drop down list? The data I want to display in the drop down list is ID="dgvFitters".Also, is it possible to display the data in a datagrid and in a drop down list simultaneously?

does anyone have an thoughts as to what might be going on ? I 've had a sr. developer look at this to make sure the code was right... He seems to think this could be a bug...
I have a table Person (in my database) which has fields like PersonID, PersonName, PersonSurname, etc. What I'd like to do is to bind the PersonName + PersonSurname (e.g. Mark Black) as values for displaying the data in drop down list and PersonID as the data identifier.
As I'm still new with Entity Framework I'm not sure how to manage to do it.
