I have column defined with template : "object.type" and it is dropdownlist (there are multiple types to search).

It has editor:

                editor : function (container, options) {
                        $('<input data-text-field="display" data-value-field="id" data-bind="value:' + options.field + '"/>')
                            .appendTo(container)
                            .kendoDropDownList({
                                index: 0,
                                dataTextField: "display",
                                dataValueField: "id",
                                dataSource: usergroupConf.permissions
                            });
                    },

so element for this column is object with keys id and display, e.g.

{
  "id":"1",
  "display":"Big"
}

now, I have defined filterable property for that column:

                filterable : {
                    extra : false,
                    ui : function(element) {
                        element.kendoDropDownList({
                            index: 0,
                            dataTextField: "display",
                            dataValueField: "id",
                            dataSource: usergroupConf.permissions
                        });
                    }
                }

when I click on filter box it displays filter fine, but when I select some value from it I get error :

Uncaught TypeError: undefined is not a function

So in short,

how to filter columns in kendo's grid which are dropdowns?

因此，经过大量研究，解决方案正在紧随其后。在剑道网格中使用外键。

  1. 创建附加字段，该字段是下拉列表中选择的值的键

  2. 对于该列，将绑定到下拉列表的板条箱编辑器，它将更改此新字段

            {
            field: 'permission_id',
            title : 'Permission',
            // values : usergroupConf.permissions,
            template : "#= permission.display #",
            editor : function (container, options) {
                // bind it to permission, but update permission_id as well (because of enabled filtering)
                $('<input data-text-field="display" data-value-field="id" data-bind="value:permission"/>')
                    .appendTo(container)
                    .kendoDropDownList({
                        index: 0,
                        dataTextField: "display",
                        dataValueField: "id",
                        dataSource: usergroupConf.permissions,
                        select : function(e) {
                            options.model.permission_id = this.dataItem(e.item.index()).id;
                        }
                    });
            },
            filterable : {
                extra : false,
                ui : function(element) {
                    element.kendoDropDownList({
                        dataSource: usergroupConf.permissions,
                        dataTextField: "display",
                        dataValueField: "id",
                        optionLabel: "--Select Value--"
                    });
                }
            }
        },

  3. 这是数据源

        dataSource: new kendo.data.DataSource({
        // pageSize: 10,
        serverPaging: false,
        schema: {
            model: {
                id : 'id',
                fields: {
                    'id' : {},
                    'name' : {
                        editable : false,
                        nullable : false
                    },
                    'permission' : {
                        editable : true
                    },
                    'permission_id' : { // we'll have permission_id to enable filter (kendo doesn't support filtering through objects (what permission column is) by default)
                        editable : true,
                        type : 'number'
                    }
                }
            }
        },

所以最后，在填充数据时，您必须将权限添加为对象：

{
  "id":1
  "display":"Move"
}

和

permission_id:1
