John,

>Thank you Tim for the response. I'm focusing on MM 2.4 for now. I've installed the DevExpress third party code and upgraded it to run with the latest (8.1). It sounds like you're saying to me I shouldn't bother messing with the MM source code and that I should create my own base forms with the appropriate DX controls instead?

That is one way to do it. The mmMaintenanceForm is subclassed from mmBusinessForm and has very little code in it. If you open the Mere Mortals Framework Windows Forms solution and look at the class for mmMaintenanceForm you can see what is there.

You could just create your own MyMaintenanceForm subclassed from mmBusinessForm and add the controls you want to create a maintenance form including your Devx controls. But then look at Kevin's code in his maintenance form so you can make sure you hook up the few things he has. No big deal really as most of the functionality is inherited. It shouldn't take you an hour to create your own. Your biggest issue will be when you replace the Close, Delete, New buttons with buttons from Devx you will need to see what kevin has in those buttons so you can make them work the same also. I can't remember if Kevin has close, delete, new buttons in the dev x line, but if he does than it is even easier.
