javascript - MVC Kendo 网格自定义过滤器

Question

基本上，我正在寻找这个演示的 MVC 版本:

http://demos.telerik.com/kendo-ui/grid/filter-menu-customization

这是我目前拥有的:

.Columns(columns =>
        {
            columns.Bound(e => e.ID)
                .Hidden();
            columns.Bound(e => e.SearchFunctionCode)
                .Hidden();
            columns.Bound(e => e.SearchFunctionDesc)                
                .Title("Search Function")
                .Filterable( *** WHAT GOES HERE? *** )
                .HtmlAttributes(new { style = "text-align: center" })
                .HeaderHtmlAttributes(new { style = "text-align: center" });

我是否仍然引用 javascript，还是有其他方法？

<script type="text/javascript">
    function SearchFunctionFilter(element) {
        element.kendoDropDownList({
            dataSource: searchfunctions(),
            optionLabel: "--Select Value--"
        });
    }
</script>

是的，我们需要在 javascript 中定义指定的过滤器函数，如下所示。

.Columns(columns => {
        columns.Template(@<text>@item.FirstName  @item.LastName</text>)
                .ClientTemplate("#=FirstName# #=LastName#")
                .Title("Name");
        columns.Bound(e => e.City)
                .Filterable(filterable => filterable.UI("cityFilter"))
                .Width(200);
        columns.Bound(e => e.Title)
                .Filterable(filterable => filterable.UI("titleFilter"))
                .Width(350);   
    })    
    .Filterable(filterable => filterable
        .Extra(false)
        .Operators(operators => operators
            .ForString(str => str.Clear()
                .StartsWith("Starts with")
                .IsEqualTo("Is equal to")
                .IsNotEqualTo("Is not equal to")
            ))
        )   
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("FilterMenuCustomization_Read", "Grid"))
     )
)

<script type="text/javascript">
    function cityFilter(element) {
        element.kendoDropDownList({
            dataSource: {
                transport: {
                    read: "@Url.Action("FilterMenuCustomization_Cities")"
                }
            },
            optionLabel: "--Select Value--"
        });
    }

    function titleFilter(element) {
        element.kendoAutoComplete({
            dataSource: {
                transport: {
                    read: "@Url.Action("FilterMenuCustomization_Titles")"
                }
            }
        });
    }
</script>
