我有下拉城市的过滤器。当我从下拉列表中选择城市并单击按钮搜索以在该城市的网格视图中显示数据时，我想要那个。

第一个问题

1）如何从下拉列表中获取值并传递给按钮和调用控制器？

2）我尝试不使用下拉菜单，当直接在 Read 方法中填充值但什么都没有时，我的 gridview 是空的。

这是我的代码

部分视图“过滤器”，使用 gridview 和控制器中填充 gridview 的方法查看。

@{
    ViewBag.Title = "Filter";    
}
<div class="filter-all">
    <div class="filter-dropdown">
  <div class="filter-part">
            <div class="custom-label-div">
                City:</div>
            <div class="defaultSize">
                @(Html.Kendo().DropDownList()
  .Name("City")
  .HtmlAttributes(new { style = "width:250px" })
  .DataTextField("CityName")
  .DataValueField("CityID")
  .OptionLabel("...")
  .DataSource(source =>
  {
      source.Read(read =>
      {
          read.Action("GetCities", "Filter");
      });
  })
   )
            </div>
        </div>
    </div>
    <div class="filter-buttons">
        <div class="button-filter-div">
            <input type="button" value="Search City" onclick="location.href='@Url.Action("Index", "MFS3")'" class="k-button" style="width: 80px"/>
            <input type="button" value="Cancel" onclick="location.href='@Url.Action("Index", "Preview")'" class="k-button" style="width: 80px"/>
        </div>
    </div>
</div>

I resolved this via jQuery and added parameter in my Index method

$('#btnSearch').click(function () {
        var cityID = $("#City").data("kendoDropDownList").value();
        document.location = "/MFS3/Index?cityId=" + cityID;
    });


  public ActionResult Index(int cityId)
        {
            return View(GetMFS3(cityId)); 
        }
