I'm trying to make a wpf application similar to the file explorer in visual studio.
What I have planned is to display the table of contents in a tree format with a treeview and to display a corresponding datagrid when clicking the treeview item.
I'm new to wpf, so I didn't know anything and tried various methods.
In the first method, since the contents of the datagrid that appear when you click on each treeview item should all be different, I created 7 datagrids in the xaml file and tried to control it with the visibility property.
But this method didn't work and it failed.
In the second way, the code is structured like this in the xaml file. As I expected, clicking on each treeview item loads the corresponding datagrid.
But if I do it the second way, I don't know how to access each element.
So my questions are this.
How to access each cell in below code?
(For example. how to access Name variable?(it's in "TEST1_CLICKED" function)

- trivial question (you can ignore) Can i display the corresponding datagrid every time when i click on the treeviewitem? (assuming multiple datagrid - in xaml) (what i failed)
