When I run the code snippet in Visual Studio 2013 and 2015, I get two different results. On Visual Studio 2015, I get NullReference, and in 2013, it works as it should. Visual Studio 2015 also runs on Windows 10 and 2013 on Windows 8.1. Piece of code:
private static T FindParentOfType<T>(DependencyObject o)
{
dynamic parent = VisualTreeHelper.GetParent(o);
return parent.GetType().IsAssignableFrom(typeof(T)) ? parent : FindParentOfType<T>(parent);
}
The code is called using:
Grid RiskGrid = FindParentOfType<Grid>(ChampViewModelSel);
Error checking IsAssginableFromat the check IsAssginableFrombecause she finds Canvas VS2015 instead of the desired mesh, which is in VS2013?
