My question is a design question :
let's say i have a data entry web page with 4 drop down lists, each depending on the previous one, and a bunch of text boxes.

• ddlCountry (DropDownList)
• ddlState (DropDownList)
• ddlCity (DropDownList)
• ddlBoro (DropDownList)
• txtAddress (TxtBox)
• txtZipcode(TxtBox)

and an object that represents a datarow with a value for each:

• countrySeqid
• stateSeqid
• citySeqid
• boroSeqid
• address

• zipCode

  naturally the country, state, city and boro values will be values of primary keys of some lookup tables.

when the user chooses to edits that record, i would load it from database and load it into the page. the issue that I have is how to streamline loading the DropDownLists.

i have some code that would grab the object,look thru its values and move them to their corresponding input controls in one shot. but in this case i will have to load the ddlCountry with possible values, then assign values, then do the same thing for the rest of the ddls.

I guess i am looking for an elegant solution. i am using asp.net, but i think it is irrelevant to the question. i am looking more into a design pattern.
