Prism RegionManager.Region[“”].GetView(“string”) always returns null

问题

I have an import in my view model for the regionmanager

[Import]
private IRegionManager _regionManager;

I want to be able to get a view and remove it from a region.

First step, get the view i.e.

_regionManager.Regions["MainRegion"].GetView("ViewName");

Whatever I do this always returns null. I specify a name for my view when adding it using view injection. When I try to use the above method though it doesn't work. I've seen other posts regarding this matter but none that seem to explain how to resolve it.

回答1:

I have sorted it out. Misunderstanding on my part.

When I was adding the view to my region I was using

View myView = new myView();
myView.Name = "ABC";
_regionManager.Regions["MainRegion"].Add(myView);

This did not work when I tried GetView("ABC")

What I should have done was as follows

_regionManager.Regions["MainRegion"].Add(myView, "asdf");

and then later on I can call

_regionManager.Regions["MainRegion"].GetView("asdf");
