Question Inline Validation

[roary86]

I was wondering if anyone has done this before or has seen code that does this. I want to validate the data inline (when the object looses focus).
Thanks in advance

You can write your custom code to validate the control when it loses focus. Although it provides a good end user experience, its always advisable to do some server side validation before processing the data.

Or, you can use Validation Control:
