Hi

i am binding the data selected from database to dropdownlist.
 
select companynumber, companyname from company
 
dropdownlist.datatextfield = "companyname"
dropdownlist.datavaluefield = "companynumber"
dropdownlist.databind().
 
with this code in the drop down list i will have companynames.
 
what i want is both companyname - companynumber in dropdownlist.
when i am saying dropdownlist.datatextfield = "companyname" & "companynumber" its
throwing error. is there any other way to do it.

you will need to get that into the query, The 'auto wire up' does not support multiple of user defined fields.

Change your query to

select companyname + " - " + companynumber as displayname
,       CompanyNumber
from ... etc

then link 'displayname' as the display field

If you bind it to a field on your query it is hard to add two fields together. You can query the database for the fills and then add to dropdown with a for loop.

I realize these are not the greatest examples but should help steer you in the right direction.

TOm is correct...change your select statement to include the concatenated value for your combo box.
