I've run into an interesting issue and hoping someone can shed some light.

I have a radNumericTextBox that has its value being validated and changed if invalid via set_textboxvalue function. The set_textboxvalue is working fine, however I found that if you click back in the textbox the value will return to what it was originally. What's causing this?

Using version 2008.1.515.20

                $find('radTbQty').set_textBoxValue('1000');
