DropDownList in FormView binding

Question

I want to bind dropdownlist to List, in code behind.

Answer 1

You can populate the DropDownList with another DataSource, assuming the valid values are in the database. Check out this video:

It's using an EntityDataSource instead of an ObjectDataSource, but the principle should still work.

If you want a "(none)" type option for null, see section "Converting Null in Template Fields" on this page:

Specifically:

        (none)

Notice the the "AppendDataBoundItems" attribute and the "asp:ListItem" element.
