NumericTextBox: problem with validation of step

[Jesper]

Setting step for a NumericTextBox seems to only affect the behaviour of the spinners.
"Manual" user input is not validated, so the user can enter numerals that aren't multiples of the step value.
Neither does using a Kendo Validator work.

See this fiddle:

Hi Jesper,

The step is not supposed to affect the user input, but only the spinners. This is the default behaviour of the NumericTextBox widget, the functionality that you are looking for is available in Kendo Slider.

Regarding validation, to enable it you will have to add the data-type="number" attribute to the corresponding input. For example:

<input id="box" data-type="number" step="50" min="0" max="100" />

For convenience I have updated your fiddle, please check the result: http://jsfiddle.net/valchev/Ns6sd/9/ 

I hope this helps.

Kind regards,

Many thanks for your answer.
I wasn't aware that the data-type attribute was required for validation to work. Perhaps the intended data-type could be inferred from the validations used? I'm thinking step would only ever be used with numbers?

Hello Jesper,

Thank you for the feedback, I will forward it to the team.

The numeric text box initialization changes the type of the input element to text for IE compatibility reasons. That is why in order to trigger the validation it is required to explicitly set the data-type attribute.
