Hi Eltiel,

In order to call a JavaScript method you can intercept the OnValueChanging client-side event of the RadNumericTextBox like demonstrated below:

ASPX:

<telerik:RadNumericTextBox runat="server" ID="RadNumericTextBox" ShowSpinButtons="true">
        <ClientEvents OnValueChanging="ValueChanging" />
    </telerik:RadNumericTextBox>

JavaScript:

function ValueChanging(sender,args)
       {
           MyCustomMethod();
       }

The second requirements is difficult to understand. Do you want do disable both of the spin buttons? Please elaborate more on your requirements so we could give you a more precise answer.

All the best,
