Dear Support team,

My company started using new kendo feature - Filter Multi Checkboxes. But we found an error which is connected to changing datasource in existing grid. More is shown in attached dojo link:

http://dojo.telerik.com/AkAxO

As you can see, after clicking 'Change data source' button, more than one filter panel is appearing when you are trying to filter column. Kendo creates new panel for every button click.

I looked into sources and the problem is related to creating FilterMultiCheck element - init method is runned every data source change, which is incorrect in our situation. 

Please let us know how we should solve this problem.

You should click Apply / Clear button on the particular filter instead of hiding it by clicking on the filter icon. After that you should see multiply filter pop-ups. The number of pop-ups should be related to the number of data source changes.

We created workaround to this error by adding in function _createLink registering off from event click before attaching to event.

kendo.ui.FilterMultiCheck.prototype._createLink = function () {
    var NS = '.kendoFilterMenu';
    var element = this.element;
    var link = element.addClass("k-with-icon k-filterable").find(".k-grid-filter");
 
    if (!link[0]) {
        link = element.prepend('<a class="k-grid-filter" href="#"><span class="k-icon k-filter"/></a>').find(".k-grid-filter");
    }
 
    link.off("click" + NS); // this line
    this._link = link.attr("tabindex", -1).on("click" + NS, $.proxy(this._click, this));
};

Hello Marcin,

I have just pushed a fix in the Kendo UI Grid file. And it will be available with the next internal build.
