Hello

I want to bind list to TreeView. But it should work like that:

I work with entity framework. In easiest case I have 2 tables with 2 associations.

Customer
Product

Customer is connected with itself
Customer.CustomerID - Customer.ParentID
and
Product.CustomerID - Customer.CustomerID

Right now I want to populate TreeView and achieve something like this:

Customer1
    SubCustomer1
        Product1
        Product2
    Product3
Customer2
    Product4
Customer3
    SubCustomer2
        Product5
    SubCustomer3
        SubCustomer4
             Product6
        Product7
    Product8

I want to see only Name properties and somehow detect which one is clicked.

Customer Table has 3 navigation properties
Products
CustomerChildren
CustomerParent

Product table has 3 navigation properties but I don't want to use it in TreeView.

In runtime I want to click on some Product, detect that Product is selected (stop if customer is selected) and then make some database modification according to other controls.

Can someone help?

Solution 2

I wanted use some automatic binding but I create recursive function to populate TreeView with TreeViewItems and then TreeViewItem.Items with another TreeViewItems but this solution isn't efficient. It is very slow solution.
