Hi Karel,
I am afraid there is not such a property holding the name/key of the DataTemplate set as column's CellTemplate available.
As to Binding columns dynamically, you can check
this github example on Binding columns from view model which allows dynamically adding and removing columns.
Although GitHub is a very well-known platform we saw a better and easier approach for reviewing our examples developing our brand new SDK Samples Browser. You can also use it to review the examples.
