问题 I've got a View rendering two dropdownlists. The controllers for the dropdownlists work fine. They call methods in a repository class for the DB selections.

The dropdowns in the View use a single model: @model BudgetDemo.Models.BudgetsActualsViewModel The Partial View displaying the table data uses IEnumerable: @model IEnumerable<BudgetDemo.Models.BudgetsActualsViewModel
