cascadeFromParentField String

Defines the parent field to be used to retain value from. This value will be used further to filter the dataSource. If not defined the value from the parent's dataValueField will be used.

Example

<input id="parent" />
<input id="child" />
<script>
$("#parent").kendoComboBox({
    dataTextField: "name",
    dataValueField: "id",
    dataSource: [
        { name: "Parent1", id: 123, cascadeId: 1 },
        { name: "Parent2", id: 234, cascadeId: 2 }
    ]
});

$("#child").kendoComboBox({
    cascadeFrom: "parent",
    cascadeFromField: "parentId",
    cascadeFromParentField: "cascadeId",
    dataTextField: "name",
    dataValueField: "id",
    dataSource: [
        { name: "Child1", id: 1, parentId: 1 },
        { name: "Child2", id: 2, parentId: 2 },
        { name: "Child3", id: 3, parentId: 1 },
        { name: "Child4", id: 4, parentId: 2 }
    ]
});
</script>
