MVC Kendo網格自定義過濾器

Question

基本上，我正在尋找這個演示的MVC版本：

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

這是我目前擁有的：

.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" });

我仍然引用javascript，還是有另一種方法？

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

是的，我們需要在javascript中定義指定的過濾器函數，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>

馬爾坎的答案應該有效。 您需要做的就是在每列上都有一個單獨的過濾器。 只需將“filterable”列替換為您喜歡的任何內容，如下所示：

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