I am trying to select a specific option from a dropdown list when the page is rendered.

On my Controller I have this code:
ViewBag.PropertyId = new SelectList(db.Properties, "PropertyId", "PropertyName", id.ToString());

On my view, This does not work. The selected option is the first option always.
@Html.DropDownList("PropertyId", (SelectList)ViewBag.PropertyId)

This does work on my view, the correct option is selected. However, I can not save this because I need the name of the select list to be PropertyId, so that it is posted correctly.
@Html.DropDownList("sadgfsadsaf", (SelectList)ViewBag.PropertyId)

Can someone please help me understand what i should be doing here? I understand i should use a viewmodel instead of Viewbag but I just want get this working first.

Thank you

    I’ve had this same issue before and it was a name collision. Try changing your dropdown and/or value name and see what happens.
