I'm using the DropDownListFor helper method inside of an edit page and I'm not having any luck getting it to select the value that I specify. I noticed a similar question on Stackoverflow. The suggested workaround was to, "populate your SelectList in the view code". The problem is that I've already tried this and it's still not working.
<%= Html.DropDownListFor(model => model.States, new SelectList(Model.States.OrderBy(s => s.StateAbbr), "StateAbbr", "StateName", Model.AddressStateAbbr), "-- Select State --")%>
I have set a breakpoint and have verified the existence (and validity) of model.AddressStateAbbr. I'm just not sure what I'm missing.
After researching for an hour, I found the problem that is causing the selected to not get set to DropDownListFor
. The reason is you are using ViewBag's name the same as the model's property.
Example
public class employee_insignia { public int id{get;set;} public string name{get;set;} public int insignia{get;set;}//This property will store insignia id } // If your ViewBag's name same as your property name ViewBag.Insignia = new SelectList(db.MtInsignia.AsEnumerable(), "id", "description", 1);
View
@Html.DropDownListFor(model => model.insignia, (SelectList)ViewBag.Insignia, "Please select value")
The selected option will not set to dropdownlist, BUT When you change ViewBag's name to different name the selected option will show correct.
Example
ViewBag.InsigniaList = new SelectList(db.MtInsignia.AsEnumerable(), "id", "description", 1);
View
@Html.DropDownListFor(model => model.insignia, (SelectList)ViewBag.InsigniaList , "Please select value")
