C# Gridlookupedit实体框架

如何正确填写gridlookupedit？
我找不到错误

方法fill gridlookupedit

    public void CargaGLEVerdadero()
    {
        pcbjEntidades contexto = new pcbjEntidades();
        IList consultaModeloInsumosVerdadera = (from ModeloInsumoes in contexto.ModeloInsumoes
                                                where
                                                  ModeloInsumoes.Activo == true
                                                select new
                                                {
                                                    ModeloInsumoes.NombreModeloInsumo
                                                }).ToList();

        gleNombreModelo.Properties.DataSource = new BindingSource(consultaModeloInsumosVerdadera, "");
    }

形式建构

public frmAgregarMarca()
    {
        InitializeComponent();
        CargaGLEVerdadero();
    }

此问题与GridLookup没有直接关系，而是与EF/Winforms互操作相关

由于您使用的是DevXPress，因此可以使用。此功能可用于threir套件中的任何数据感知控件，它知道如何正确执行操作，并可为您完成所有工作：

// This line of code is generated by Data Source Configuration Wizard
// Instantiate a new DBContext
WindowsFormsApplication2.CountriesDBEntities dbContext = new WindowsFormsApplication2.CountriesDBEntities();
// Call the Load method to get the data for the given DbSet from the database.
dbContext.Countries.Load();
// This line of code is generated by Data Source Configuration Wizard
gridLookUpEdit1.Properties.DataSource = dbContext.Countries.Local.ToBindingList();

然后您可以自定义向导的输出：

dbContext.Countries.Where(c => c.Capital.StartsWith("A")).Load();

如果看到图片，必须仅用“L222011”填写gridlookupedit
