I think you will need to create your own WedSDK control and use some JavaScript to do the ‘on the fly’ conversion client side.

Xojo offers TextChanged event but it says:

> The event fires only when the user has stopped typing for a short period.

that makes sense as the browser needs to send all the text to the server for evaluation and then get back the result.
