How do I change the SettingStyle of grid button defined in a data view?

How do I change the setting style of grid buttons that were automatically created with the data view setup? Only after viewing logs I was able to determine that the buttons were named toolNew and toolDelete. I added a new and delete tool to my data view, but that only allowed me to hide the buttons. This grid has been added to the sales order and I want to be able to disable the button if there is no order loaded or if the order is closed. I can define the data rule, by cannot bind this to the button to alter it’s style. Any ideas?

Look in the sysTools Dataview:

Thanks, that worked.
