DataBinding: 'System.Web.Mvc.SelectListItem' does not contain a property with the name 'CategoryTypeID'

Question

I am using MVC. I want to pass the category data I entered from my view and passed to my Post/ Createcontroller, but it\'s not\'s letting me pass my categoryTypeID that I ha

Answer 1

I faced this error. I was binding an object of the View Model:

editPanelViewModel.Panel = new SelectList(panels, "PanelId", "PanelName");

In the View, I created the ListBox like this:

@Html.ListBoxFor(m => m.Panel, new SelectList(Model.Panel, "PanelId", "PanelName"))

It should be like this in fact:

@Html.ListBoxFor(m => m.Panel, new SelectList(Model.Panel, "Value", "Text"))

Answer 2

You are defining your SelectList twice, in your controller as well as in your view.

Keep the view clean. Just the following would be enough in your case: @Html.DropDownListFor(model => model.CategoryTypeID, (SelectList)ViewBag.CategoryTypes)

I have to admit that DropDownListFor is quite confusing in the beginning :)
