Question

mvc asp.net @Html.DropDownList如何实现滚动条呀，代码见详细描述，谢谢。

@Html.DropDownList("ThisYear", ViewBag.YearSelectList as IEnumerable<SelectListItem>, new { @class = "easyui-combobox", editable = "false", panelHeight = "auto", style = "width: 100px;" })

Answer 1

@Html.DropDownList("ThisYear", ViewBag.YearSelectList as IEnumerable<SelectListItem>,new {size=5})

<select id="ThisYear" name="ThisYear" size="5">

超过 5 个就会出现滚动条，但是也有一个问题，固定了下拉框的 size 是 5，如果元素个数小于 Size，就会变成这样

希望对您有帮助
