Master-Detail - In Grid mode, a detail View whose DataController.DetailKeyFieldNames or DataController.MasterKeyFieldNames property is set to an empty string does not load data

created 6 years ago

18.2.4 appears to have broken master detail data display in a multi-level grid.   The attached project when compiled with 18.2.3 will show the detail information properly when expanding the master level.  The same exact project when compiled with 18.2.4 doesn't display the detail data.

    Hello Terry,

    Thank you for sharing your sample project. This looks strange. I installed the 18.2.3 build of our cotnrols and compiled your example with it. I confirm that the modern 18.2.4 build behaves differently. It may take us some time to examine this scenario.
