我有2个下拉列表:
<div class="control-group">
@Html.LabelFor(x => x.ServiceId)
@Html.DropDownListFor(x => x.ServiceId, new SelectList(Model.ServiceList, "Id", "Title"), new { @class = "open" })
</div>
<div class="control-group">
@Html.LabelFor(x => x.ServiceShareId)
@Html.DropDownListFor(x => x.ServiceShareId, new SelectList(Model.ServiceShareList, "Id", "Title"), new { @class = "open" })
</div>
我想按服务下拉列表选择的值过滤服务共享值。怎么办?
