Allow numeric value to 3-digits right of decimal point.

[Ankit]

 

I am using below code and want to restrict input so user can only Allow numeric value to 3-digits right of decimal point.

for ex:

123.00

123

12.45

 <telerik:RadNumericTextBox ID="txtFactor" runat="server" MaxLength="5"
                                                MinValue="0.00" NumberFormat-DecimalDigits="<%$ Resources:Common,decimalDigitsTwo%>"
                                                Width="60px">
                                                 <ClientEvents OnBlur="CurrentYear" />
                                            </telerik:RadNumericTextBox>

I can use regex ^(\d{0,3})(\.[0-9]{0,2})?$  but looking for any inbuild function .

Hello Ankit,

You can achieve the desired behavior by adjusting the NumberFormat-DecimalDigits property:

<telerik:RadNumericTextBox 
    ID="txtFactor" 
    runat="server" 
    MaxLength="5"
    Value="69"
    NumberFormat-DecimalDigits="2"> // Setting this will limit the numbers after the decimal point a user can insert (in this case 2)
</telerik:RadNumericTextBox>
