Hello.

I see that this control has the property "Maximum" but I need specify a MaxLenght number value, for example a max lenght of three digits only must to allow entry a number with  ###  format.

May you help me?

Hello David,

Please, check our online help article of RadNumericUpDown on Formatting. You can use NumberFormatInfo.NumberDecimalDigits to control the display value of RadNumericUpDown.

Hello Dani,

The NumberDecimalDigits  only allow specify the Decimal format, I need to limit the integer part of a number.

Thank you

Hi David,

It is not possible to limit the input of RadNumericUpDown at the time it is being input. You can use the Minimum and Maximum properties to limit the RadNumericUpDown value when the user has finished editing. And you can wire up some DataValidation logic as shown in this online example.

To accomplish the input length validation, I would suggest that you try using the RadMaskedInputTextBox, instead.

I hope this helps.
