For cases where validation after the fact isn't good enough there should be an option that disallows setting numeric textboxes to null. If the user sets it to null and moves to another field the textbox should reset to 0.

The Kendo UI NumericTextBox hides the decimal portion of its value when focus is in the control and when the decimal part is zero. For example a value of 1,345.00 will appear as 1345 when the focus is put in the control. If the decimal part is non-zero then the value is shown. From a usability viewpoint the disappearing zeros is inconsistent and can be misleading/confusing to a user who may not realize that they can enter a decimal part.

So I think it would be valuable for the control to always show the decimal part of the value.

It is better if kendo numeric textbox formats value (comma will be added after 3 decimals) as user types, especially for currency values.

There are so many jQuery plugins available in market to achieve this. Kendo Numeric text box is not working as expected when integrate with these plugins.

Please focus on adding flexibility to the numerictextbox. I'm jumping through hoops to get a field with a displayed percentage of 75.75% to appear the same way in edit mode. I understand the need to keep the control reasonably rigid, but I would hope additional customization options could be add. I gave up and am doing everything in a custom editor/ input text box.   

Add a popup calc like this one : http://keith-wood.name/calculator.html

When you use a NumericTextBox without attribute title, the widget creates automatically one with the current internal value, showing a annoying and unnecessary tooltip.

We would like remove this behavior or change it with a configuration item.

Something like:

<input id="currency" type="number" title="" />

$("#currency").kendoNumericTextBox({
    autoTooltip: false,
});

Provide an option for the Kendo UI NumericTextBox to select its value on focus.

This would be a useful feature for data entry situations so you can start typing immediately. 

We are aware of the proposed how to article but this is not a good solution for large applications. 

Can we have something like "selectOnFocus: true". The code fix for this could be:

When using the percentTextBox control, it would be nice if there was an option to have the control allow the editing of the data as a percent.  Currently it will show the percent as a decimal value (e.g. 50% would show .5)  For our users, it's more intuitive for them to enter the percent instead of the decimal value.  Kendo would need to do the conversion to/from percent and decimal behind the scenes so that the data is saved properly on the underlying model as a decimal value.

Currently AZERTY keyboards are not supported in NumericTextBox. In consequence:
1. It is not possible to enter a decimal separator in the control (because the key combination is "Shift + ;" - this can only be done using Caps Lock or the NumPad
2. It is possible to enter ; instead of the decimal separator
3. It is possible to enter the special symbols that are in the place of digits in QWERTY keyboards (again because digits are written using the Shift key).

The NumericTextBox currently has the ability to specify "decimals" - the number of decimal places allowed in the box. When a user types in a number with more decimal places than the box is configured for, the number gets rounded to the decimal precision.

What we'd like is to actually STOP the user from being able to type in more decimals than they're allowed. We don't want it to round; we want the user to just be disallowed from entering in a number that would be rounded.

I find it really confusing that when you hover over the kendo numeric textbox, the mouse turns 'disabled'.  the users i've worked with have no idea that they can click on the numerictextbox to change values inside.  Very not-intuitive.
