I had a request from my users to be able to identify the required fields prior to hitting the save button. Here is a very simple test/sample app that I used to test and debug prior to implementing in production code and it demonstrates how I implemented this request using the sample strataframe data. I hope this will save someone else a little time if they need this functionality in their app.

It seems to work fine with both S.F. controls and Dev Express subclassed I am not sure about Infragistics but it should be ok but dont come crying to me if it doesnt work
