I want to implement a performance feature which works like the following: If I hold down a button, a snapshot is created. While I’m holding down that button, I want to change values of some controls. Once I release this button, the snapshot is restored.
I can’t find anything about snapshots in the documentation so chances are high that it’s not implemented. If this is the case, is there any alternative? I thought it might be sufficient to get all controls of a page and store their value but there seems to be no designated way to get all controls on a page
