There is no ViewData item of type 'IEnumerable' that has the key country

Question

While binding dropdown in MVC, I always get this error: There is no ViewData item of type \'IEnumerable\' that has the key country.

If you were using DropDownListFor like this:

@Html.DropDownListFor(m => m.SelectedItemId, Model.MySelectList)

where MySelectList in the model was a property of type SelectList, this error could be thrown if the property was null.

Avoid this by simple initializing it in constructor, like this:

public MyModel()
{
    MySelectList = new SelectList(new List()); // empty list of anything...
}

I know it's not the OP's case, but this might help someone like me which had the same error due to this.
