View 1 RepliesI have a dropdown list which has items bound to it using sql datasource.
In the database i have the numeric values corresponding to each item.
Now there are many such dropdown list's and on selection of each item i want to form a 14 digit numeric code,which i need to use further for some more functionality.
How can i convert a selected item from a dropdownlist to a numeric digit??or how can i bind the items in the dropdownlist to a database having numeric value for each item?
