I am a newbie to WPF. The question is about displaying a tree structure in WPF.
I have a WPF app, which will connect to a remote database. One table (Taxonomy table) in the DB has two columns: "Parent node" (varchar(50)), and "Child node"(varchar(50)). Now I want to display that phylogenetic tree (as shown in the pic). Each nodes on the tree is coupled with a checkBox, and therefore, the user is able to select multiple nodes as they need.
Due to lack of knowledge in WPF, I really have no idea how to achieve that. What controls (or combination of controls) should be used here? Is WCF necessary in this case?
Thanks in advance.
Any suggestion or tutorial is greatly appreciated.

Im developing a window based application using wpf. i have a window with a treeview and frame in it. i want to control the data populating in the frame using the treveview nodes. Just like our file explorer in our windows machines. for that i need to know what is the level of the node i have selected on the treeview. I know how to do this with window forms but im new to WPF. Please some one kindly help me how to get the nodelevel of treeview in WPF.
Note: im populating the treeview from a backend table programatically
As #Jobi said in the following link : the level of a treeview in WPF?
The direct answer to your question is that there is no level property in WPF.
There is no one to one relationship between the winforms controls and wpf control. Because the underlying architecture and usage is totally different in both. In WPF you will bind a heirarchical data(LinkedList kind of Datastructure) to a TreeView and define a HeirarchicalDataTemplate to the Treeview.ItemTemplate property
I hope this will help you.
I could not able to design a table using listbox. For the past 5 days, am doing nothing but these things, I am totally naive to Windows Phone application development.For me, the problem is the table that i'm designing will not fit into a single page. I want the user to drag the table to view the off-contents. But using list box (particularly, listbox item) i could not able to achieve this. After this, i need to create dynamic rows to the table.Could anybody please help to create the table?

I shall create a visual component to display and navigate a large network of nodes. Nodes have input terminals and output terminals. The total network is too large to be displayed on a single screen.
I see that GUI component vendors have visio-like flowchart/diagramming components for free form placement. It's not exactly what I am looking for. The output should look flowchart-ish, but the functionality is more of a bunch of listboxes / stackpanel / treeview control. I suppose I could make this into a grid or something so that everything should reposition itself dynamically as the user navigates and expand sections, but it is unclear to me how I would then make the connection lines "follow" the item that it is connected to. The nodes are of various types, so there should absolutely be some kind of visual template selection (like datatemplate).
I assume that the topic of visualizing interconnected nodes is a general problem. I've also learned that WPF layout panels are powerful if you apply them correctly, so I am hoping somebody who are more versed in their functionality will be able to break it down into a sensible composition of controls.
BTW I have the Telerik UI RadControls for WPF.
Do you have any tips or solution for how this functionality can be achieved by composing WPF (and/or Telerik) controls?
Trying to create what i feel should be an easy WPF application. basically what i want it to do is have a autocomplete combobox which is bound to a sql db table. the table has 2 fields(Address and Directions)
once the user selects the record from the address combox the directions textbox below will be filled directions stored in the table.
if there are no records in the address combobox the user can then type in the combobox and add the new entry.
there will be a save button on the form that saves the new entry and will be visible in the list. Im new to WPF applications and have been trying to get this to work for weeks. Any help would be appreciated.
I would start by checking out the following discussion which will point you to several good tutorials on using the MVVM (Model-View-ViewModel) pattern with WPF.
MVVM: Tutorial from start to finish?
Other than that, you haven't really given any indication what you've tried and what isn't working so I can't really offer any other advice. But even the simplest applications in WPF are much cleaner and more easily implemented with MVVM than using code behind and drag and drop data binding.
I can't find an example of a silverlight 2 tree control that is bound to a database table. I have a table with ID and ParentID columns and I use it to populate a tree control in windows forms. I want to do the same with a silverlight tree control but I can't find any examples on how to do this. Most of the samples have the nodes hard coded. I don't need any advice on how to wcf the data table, I know that part really well. Thanks in advance.
I have not worked with the tree control myself, but I did a quick google, and found the following site Populating Silverlight TreeView from WCF Service with LINQ to SQL
It does however make use of custom classes to store the data and then makes use of LINQ to SQL to extract data from your data tables to manually construct the tree view.
Hope this helps
