Question

I 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?Please help.

E.g if i select 'WT' from dropdown list the corresponding value for it in the database table is 39 so on form submit i want '39' to be formed in codebehind. likewise on selection of all items from different dropdown list the digit formed using codebehind should be '15487523568955'

Ok while binding your dropdown list to the sql datasource, you have to make sure that you bind

dropdownlist.DataSource = <GetSQLDataSource>();
dropdownlistDataTextField="<textvalue>"; 
dropdownlistDataValueField="<numericID>";
dropdownlist.DataBind();

Then, the Textvalue will be displayed in hte dropdown list and then you can access the corresponding .
