    I want to use a RadNumericTextBox to enter a value.  If the value is outside of the MinValue/MaxValue range I want the InvalidStyle CSS to be applied, but I still want the value.  I have set AllowOutOfRangeAutoCorrect to false.  So far, so good.  The value displays properly and uncorrected.

    But when I do a postback I don't get the OnTextChanged event, presumably because the control has nuked my "invalid" value back to an empty string.  Is there an easy fix for this, or should I just do the css myself.

    Thank you.

    Hello Greg,

    When you input an incorrect value inside a RadInput control, it does not change its value, so no TextChanged event is fired and this behavior cannot be modified. You could use client script to check the content of the textbox and change its styles dynamically, similarly to what is done here:
    Showing Error Style Programmatically?

    All the best,
