populating listbox based on other control

Question

User-1213473072 posted

Hi All,

I would like to make a form, in which one listbox would be populated based on other listbox.

First listbox would have list of Categories, second - list of Subcategories, but filtered only to items connected with chosen Category.

Is it posible to do this using WebMatrix and Razor?

You can use exclusively WebMatrix and Razor, but the list of Categories would have to be submitted before the list of Subcategories will populate.  Most use javascript to accomplish this.  There are many options.  You can research for cascading dropdown lists.

If you want to use exclusively C# this thread could help: Cascading Selectboxes from Database.

Else, if you would try to use jQuery, this excellent Mike Brind's article gives you what you need: WebMatrix - jQuery Cascading Dropdown Lists.
