you cannot add the fields to datatextfield..better you prepare other column in your dataset with concating the "name"-"dept"..and then bind..it to dropdownlist..

Hi,

In your SQL query itself you do some changes .
please check the below query

SQL

SELECT name,dept,name+' - ' +dept AS DETAILS FROM TABLE_NAME

AFTER write this query then bind the table like this.

C#

dropdownbox.DataSource = ds
dropdownbox.DataValueField = "name"
dropdownbox.DataTextField = "DETAILS"
dropdownbox.DataBind()
