The WebAii framework doesn't include extended support for the SL Toolkit yet. We are working on introducing Wpf support for the R1 major release of our Automated Testing Tools in April and if all goes well we will hopefully include some updates in regards to the SL Toolkit as well. In this regard, would you please share which controls would you like to see explicitly supported by the framework? Thank you in advance for the feedback!
Meanwhile you can base your automation on the WebAii FrameworkElement and use it if possible. If you don't need some specific NumericUpDown property values for example that may be sufficient.
