[Solved] Filter Multi Checkboxes - filter panel is not refreshing after changing data source in mvvm style

[Marcin]

Dear Support team, 

We found an error that multi checkbox filter panel is not refreshing after changing data source in mvvm style. More is shown in attached dojo and screencast:

http://dojo.telerik.com/opURA

http://screencast.com/t/F4nzqodS

We created workaround about this error:

kendo.ui.FilterMultiCheck.prototype.refresh = function(e) {
    var forceUnique = this.options.forceUnique;
    var dataSource = this.dataSource;
    var filters = this.getFilterArray();

    if (this._link) {
        this._link.toggleClass("k-state-active", filters.length !== 0);
    }

    if (this.form) {
        if (e && forceUnique && e.sender === dataSource && !dataSource.options.serverPaging)
        //     (e.action == "itemchange" || e.action == "add" || e.action == "remove"))
        {
            this.checkSource.data(distinct(this.dataSource.data(),this.field));
            this.container.empty();
        }

        if (this.container.is(":empty")) {
            this.createCheckBoxes();
        }
        this.checkValues(filters);
        this.trigger('refresh');
    }
}

Problem was lack of field action in event parameter when change is done from mvvm. When we removed this condition application started working properly.

Hello Marcin,

This behavior is expected. In such scenarios you must define custom DataSource for the unique values and to update it once the Grid data source changes.
