You can use this little helper function I just wrote that will check if an element is visible for the user, in a given container. The function returns true if the element is partly visible. If you want to check if it’s fully visible, replace the last line by rect.Contains(bounds). private bool IsUserVisible(FrameworkElement element, FrameworkElement … Read more
For the point 2. I see that no one has suggested to use document.elementFromPoint(x,y), to me it is the fastest way to test if an element is nested or hidden by another. You can pass the offsets of the targetted element to the function. Here’s PPK test page on elementFromPoint. From MDN’s documentation: The elementFromPoint() … Read more
First of all, DataGridTextColumn (or any other supported dataGrid column) does not lie in the Visual tree of the DataGrid. Hence, by default it doesn’t inherit the DataContext of the DataGrid.

Because you are using a copy constructor 😉 More seriously: private variables have class level visibility; your other object is a different instance, but it is of the same class; it is therefore granted that instance members of this object will be visible from the constructor. Note the “class level”. It means instance variables from … Read more
