OPC Data Client updates values while in design mode

I have noticed that when I'm working in design mode my Data Client is updating values from my OPC Server. I have checked and I don't have any live bindings configured. I'm creating a Custom Control and embedding the EasyDAClient code within it. How can I fix this?

For most custom controls there is a DesignMode property that needs to be configured so that this only executes during runtime. This is a protected property in most cases. Once this is modified, the Data Client should no longer be updating values until program is running.
