ViewBag.cliente_id = new SelectList(db.cliente.Where(c => c.status_ativacao == 1), "id", "nome", manutencao.cliente_id);
它仍在返回所有客户。 我需要回复哪一栏' status_ativacao' =值1。 我确定在这里这样做或者我需要在下拉列表中这样做吗?
查看:
<div class="form-group">
<label class="col-sm-2 control-label" for="cliente_id">Cliente</label>
<div class="col-md-6">
@Html.DropDownList("cliente_id", (SelectList)ViewBag.Values, new { onchange = "this.form.submit();" })
@Html.ValidationMessageFor(model => model.cliente_id)
<!-- <input type="submit" value="Atualizar Cliente" class="btn btn-default"/> -->
</div>

您必须先将该查询转换为列表,如下所示:
ViewBag.cliente_id = new SelectList(db.cliente.Where(c => c.status_ativacao == 1).ToList(), "id", "nome", manutencao.cliente_id);
另外,在视图中更改Html.DropDownList,如下所示:
@Html.DropDownList("cliente_id", (SelectList)ViewBag.cliente_id, new { onchange = "this.form.submit();" })
