Thanks for the pointer. I was able to find the correct module and settings and modify the values with the ModuleController interface. I set the following keys:
mc.UpdateModuleSetting(mresult.First().Key, "DefaultPane", "bring2mind/dmx/templateview.ascx");
mc.UpdateModuleSetting(mresult.First().Key, "OverrideControlToLoad", "True");
mc.UpdateModuleSetting(mresult.First().Key, "RootId", this.Company.DmxDocumentsEntityID.ToString());
These settings do get modified correctly in the DB, but the view doesn't change to the Template View.
Can you think of anything I may be missing?
