Dynamically updating treeview node wpf
When the user selects an item in the list the same item is selected in the tree. WPF lets me get the Tree View Item that holds my Data Item by using the Item Container Generator.
A good example is the Solution Explorer in your Visual Studio. But, if you read the previous section you know that the containers are generated only once you see them so I am forced to start at the root and manually expand each tree level until I reach the required tree item.
Perhaps you have a third, better method for this case.
Please share it with me and my readers using the comments.
By the way, we can use the same solution to visualize a JSON document in a WPF Tree View.
The WPF Control displaying the tree will be: You’ll notice that whenever the property Object To Visualize changes, a new Tree Node is created with the factory method Create Tree.
I have tried getting the selected node and then expanding it in the refreshed tree view using expand() but it does not do it. Are you clearing out the tree when you fresh it, or just updating the existing nodes without removing them?
This problem is discussed in many forums but I want to present two contradicting approaches with a full explanations so that you can decide what is best.
This is something we constantly use inside the Visual Studio debugger: The debugger’s data tip control is exactly what I needed. NET object, and the result should be a tree view displaying the object’s properties and fields.
I figured there would be an easy solution I can google and copy-paste, spending no more than 10 minutes on the whole thing. Even though I found some similar solutions, they weren’t what I wanted or simply didn’t work.
Hi, I have a treeview that has to be refreshed due to data changes.
Is it possible to select the last node that they were viewing when the tree view was been populated once again?

To make long story short it means that you can tell WPF not to generate containers for tree items which are not actually visible to the user.
