Question

I’m attempting to data-bind a value to an ASP.NET DropDownList but the server complains that it doesn’t recognize the data-bind attribute:

<%=Html.DropDownList("accountSiteInstanceId", ViewData["degreePrograms"] as SelectList, new { @data-bind = "value: DegreeProgramId" } ) %>

I get the following error:
Compiler Error Message: CS0746: Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access.

Answer 1

The problem is the dash. Use dictionary based notation:

<%= Html.DropDownList("accountSiteInstanceId", ViewData["degreePrograms"] as SelectList, new Dictionary<string, object>
                {
                        {"data-bind", 
                        "DegreeProgramId"}
                }) %>
