Is it possible to have the preview string update from an OnBlur of the filter control items.  We don't want a post-back, just have the preview update, in that we have noticed the preview often does not update to reflect the last change made in the control - like changing the value of a textbox or changing a combo box value.  

Thanks

Hello Van,

The expression preview is determined entirely server-side and comes as an HTML element to the client. That means the postback is required in order to have the preview updated.

Thank you - had forgot I placed the control in an update panel and thus doing a postback each time to update preview.
