Getting a reference to a flex-grid's flex-grid-filter

    I's using MVC Tag Helpers to setup a c1-flex-grid and associated c1-flex-grid-filter. It works fine, but when I want to reference the filter in java script (for example to add a handler) I cant figure out how to do it.

    var theGrid = wijmo.Control.getControl('#ff');
    theGrid.filter //undefined
    theGrid.collectionView.filter //undefined

    I've seen theGrid.filter and theGrid.collectionView.filter used in some examples but they don't work for me.
    Most other examples generate both the grid and the filter in js using wijmo, but because I am using the ASP tag helpers this isn't an option.

    I know I can use the event binding properties in the tag helpers (e.g. filter-changing) but I am sure there are plenty of situations where I need to get a direct reference to filter, is this possible in java script?

    You may get the FlexGridFilter reference in JS code using the following code snippet:
     <c1-flex-grid auto-generate-columns="true" is-read-only="true" height="500px" id="flexgrid1">
    <c1-flex-grid-filter id="filter" default-filter-type="Both" filter-changing="filterChanging" filter-applied="filterApplied"></c1-flex-grid-filter>
    c1.documentReady(function (e) {
    var grid = wijmo.Control.getControl("#flexgrid1");
    filter = c1.getExtender(grid, "filter");
