So I have a prefilled drop down list
@Html.DropDownListFor(a => a.Item2.CategoryName, new SelectList(Model.Item1.Categories))
I want to add a default selection "All Categories" in the drop down list, how can I accomplish that?
try this
@Html.DropDownListFor(a => a.Item2.CategoryName, new SelectList(Model.Item1.Categories),"All Categories")
