I wanted to pass the dropdown text to the controller (Post) instead of the id, I do not know how I can do this.
Controller:
ViewBag.AnoCatequeseID = new SelectList(db.AnoCatequese, "AnoCatequeseID", "Ano");
View:
@Html.DropDownListFor(model => model.grupo.AnoCatequese, (SelectList)ViewBag.AnoCatequeseID, "--Escolha um ano de Catequese--", htmlAttributes: new { @class = "form-control" })
