I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?

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?
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'
