Question

my application is MVC3 using ASPX views. I have two pages, create and Edit, using the following dropdownlist:

<%= Html.DropDownList("VesselDiameter", new SelectList(new[] { "", "1", "2", "3"}))%> 

It works in create view and saves the data to the MS Sql table, however the value does not show in the edit view. If I use,

<%: Html.EditorFor(model => model.pRCA.VesselDiameter) %>

I used a similar dropdownlist in another view and it worked, but the model is different:

<%= Html.DropDownList("Vessel", new SelectList(new[] { "", "1", "2", "3"}))%>

instead of

<%: Html.EditorFor(model => model.Vessel) %>

The value is there! Would appreciate your suggestions. Thanks in advance.

Answer 1

for Model.pRCA.VesselDiameter mvc generates this id (“pRCA.VesselDiameter”) so you should prepend pRCA to id value

<%= Html.DropDownList("pRCA.VesselDiameter", new SelectList(new[] { "", "1", "2", "3"}))%>
