I need to change the background color of the text box based on the value the user enters.  For instance if the value is less than 10 then I want the background to be blue, if it greater than 20 I want it to be red.  Between 10 and 20 the background should remain white.  I have tried changing the style.background property in the onBlur client event, but have not had any success.  Any help would be appriciated.

Hello Andy,

If you want to achieve this requirement dynamically using script, you can make avail of the updateCssClass
method as demonstrated in this section:
http://docs.telerik.com/devtools/aspnet-ajax/controls/numerictextbox/client-side-programming/overview#changing-the-appearance-style-of-radinput-controls-on-the-client

You can also check the following article:
