RadMaskedNumericInput or RadMaskedCurrencyInput with SpinMode set to PositionAndValue. Mask="" (no-mask). Increasing from 1 to more than 10 works as expected. However, decreasing the 2-digitvalue to Value lower than 10 is not possible if the caret is on the right of all digits. Icreasing and decreasing is done with Keyboard Up and Down Arrow Keys. Available in LIB version: 2015.3.1019
Allow the NumPad Substract / Plus key as a valid input in a MaskedTextInput. Reason for decline: The item is duplicated. Please refer to the following link http://feedback.telerik.com/Project/143/Feedback/Details/126323-dash-on-number-keypad-doesnt-work-radmaskedtextinput
Use MaskedTextInput in Silverlight and press (Ctrl + Shift + Z). This will produce unexpected symbol.
