Bug report

When attempting to validate a cell value against a predefined finite list, the validation process fails to recognize valid entries that are present in the list. Instead, it incorrectly flags them as invalid. The issue occur when there is an empty space before the first value in the 'from' option.

Reproduction of the problem

1. Run the Dojo - https://dojo.telerik.com/@NeliK/icizisEF

Current behavior

On the first row, the 'YES' in the B1 cell is marked as invalid although it is present in the list with the valid values. the difference between row 1 and row 4 is the empty space in the validation from configuration:

"from": "{ \"YES\", \"NO\"}", //row 1
"from": "{\"YES\", \"NO\"}" //row 4

Expected/desired behavior

The empty space added in the from configuration option should not affect the validation. If the cell value is present in the list, it should be marked as valid.

I find the documentation is critically lacking with regards to the available options for a feature.

Here is an example of what I mean...

http://docs.telerik.com/kendo-ui/api/javascript/dataviz/diagram/layout#configuration-alignContent

The diagram Layout > alignContent feature "Specifies the alignment of the content."

Ok, but the documentation does not even say what the allowed values are. Instead, it just has "alignContent String (default: "start")".

Now, I guess the allowed values here are the same values allowed for an SVG text-anchor.
https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/text-anchor

How about adding those possible values to the api documentation, or including a link to the relevant area of the SVG specification?

Hope this makes sense.

There are many properties that can be set during initialization that cannot be changed through the API afterwards.

Take the Kendo UI ToolBar for example. You can add a button to the toolbar and set the text, but you cannot change the text afterwards unless you update the element directly. It may seem like a simple thing to change the text of an element, like so: $("#myButton").text("New Text"). However, if you had set the imageUrl as well, setting the text like I did above would remove the image. Knowing that, you could get the text node and update the nodeValue. That may work today but could easily be broken during a Kendo UI update (for example, if the update included a change that wraps the text in a span).

Having to deal with native elements after they have been created by the Kendo UI components is a dangerous practice for developers as it requires an internal knowledge of how elements are rendered based on the different options set. As mentioned above, it is also dangerous as any update could break our code. Therefore, it is imperative to expose methods that allow us to modify any properties through the API (where possible) to allow us to create clean and easy to maintain code.

If you search the feedback, you will see many requests to add a method here and a method there. There is even a related one to this called "Kendo Mobile: Methods to set properties dynamically".

Suggestion: When you have child elements, such as buttons on the toolbar, please allow us to update those widgets directly rather than through the parent. For example, instead of $("#myToolbar").data("kendoToolBar").enable("#myButton"), allow us to do something like this $("#myButton").data("kendoToolBarItem").enable();

We have a need to be able to provide a dropdown above the scheduler, in order to allow the end user to change the time zone of the scheduler dynamically, even after it has been initialized.  Our team was disappointed that this is currently not possible (http://www.telerik.com/forums/timezone-dropdown), but maybe in the future.  Thanks for reading.
