filter

Fired when the user is about to filter the DataSource via the filter UI.

The event handler function context (available via the this keyword) will be set to the widget instance.

Introduced in the Kendo UI 2016 R3 (2016.3.914) release.

Event Data

e.filter Object

The selected filter descriptor. If null the filter has been cleared for example by click on the clear button.

e.field String

The field for which the filter is constructed.

e.preventDefault Function

If invoked prevents adding the filter descriptor to the DataSource.

e.sender kendo.ui.Grid

The widget instance which fired the event.

Example - subscribe to the "filter" event during initialization

<div id="grid"></div>
<script>
  $("#grid").kendoGrid({
    columns: [
      { field: "name" },
      { field: "age" }
    ],
    dataSource: {
      data: [
        { id: 1, name: "Jane Doe", age: 30 },
        { id: 2, name: "John Doe", age: 33 }
      ],
      schema: {
        model: { id: "id" }
      }
    },
    filterable: true,
    filter: function(e) {
      if (e.filter == null) {
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log("filter has been cleared");
      } else {
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log(e.filter.logic);
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log(e.filter.filters[0].field);
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log(e.filter.filters[0].operator);
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log(e.filter.filters[0].value);
      }
    }
  });
