MVC Kendo网格自定义过滤器

Question

Basically, I am looking for the MVC version of this demo:

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

Here is what I currently have:

.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" });

Do I still reference the javascript, or is there another approach?

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

Yes we need to define specified filter functions in javascript like below.

.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>

Malkan's answer should work. All you need to do is have a separate filter on each column. just replace the column "filterable" with whatever you like like this:

    .Filterable(filterable => filterable
    .Extra(false)
    .Operators(operators => operators
        .ForString(str => str.Clear()
            .StartsWith("Starts with")
            .IsEqualTo("Is equal to")
            .IsNotEqualTo("Is not equal to")
        ))
    )
