Nice post, Chris. It would be much easier if you bound the TreeViewItems, and the elements in their ItemTemplate, to a ViewModel. That would remove the need to walk the visual tree, etc.

Thanks,

Hi,

I have a DB table [1] which is self referenced. DataID field is the FK of ParentDataID field. For multilevel hierarchical data binding to a WPF tree view control, I have a stored procedure that returns result set in the below mentioned order[1]. The below result set contains all the top level data with NULL ParentDataID data & all the child records has the ParentDataID field data as the pointer to its parent data.

Based on the below dataset structure, we have a requirement to bind the resultset with the multi level hierarical data to the TreeView control. How can we achive this funcionality of binding the dynamic hierarical multi level dataset to TreeView?

After binding the above result set, the Tree View data needs to be displayed in the below format. How do we implement this in the WPF Tree View?

* Test 1

* Test 2

* Test 5

* Test 3

* Test 6

* Test 4

[1]

DataID ParentDataID Description

1 NULL Test 1

2 1 Test 2

3 1 Test 3

4 1 Test 4

5 2 Test 5

6 3 Test 6

Nice example! Since you seem to know your way around TreeViews very well, I have a hopefully simple question for you.

I have two DataTables, Group and Member, how could I create a tree like this:

Group 1

Group 1a

Member A

Member B

Group 1b

Member C

Member D

That is, a Group can have other (sub)Groups as well as Members as children.
