I have an event template. Inside this template I am using a MultiSelect. It is defined like: <select data-down-Arrow="true"… .  The downArrow property does not work. I discovered via debugging the kendo.all.js file the problem. Fortunately this one is fixable outside that file:

Currently, when you have a disabled DatePicker in MVVM scenario and the setOptions method is called, the component gets enabled.  Dojo - https://dojo.telerik.com/OBMifPCW 

The widget does not provide a configuration option that allows setting the enable state. The component can be improved by adding an enabled configuration option, and also by avoiding enabling the component after the setOptions method is used.

Hi Team,

I would like to see a no-data-template be included for the Kendo UI Chart when there is no data.

Thank you!

Hi,

we found a hard to reproduce bug in the combobox control. It appears infrequently while typing in the combobox input, if the combobox has grouping and the fixed header enabled. It does not seem to have functional implications to the control but it produces a javascript error.

Stacktrace:

_firstVisibleItem: function () {
    for (var t = this.element[0], n = this.content[0], i = n.scrollTop, r = e(t.children[0]).height(), o = Math.floor(i / r) || 0, a = t.children[o] || t.lastChild, s = a.offsetTop < i; a; ) if (s) {
      if (a.offsetTop + r > i || !a.nextSibling) break;
      a = a.nextSibling
    } else {
      if (a.offsetTop <= i || !a.previousSibling) break;
      a = a.previousSibling
    }
    return this._view[e(a).data('offset-index')]
  }

It seems to be a timing problem where the list is already loading again while the scroll from the item selection is not finished.
