I would like to create a 2-tier treeview. The parent nodes would simply be text, but the child nodes would have three radiobuttons and a textblock (horizontal stackpanel). Is this possible with the RadTreeView and databinding?
Regarding the databinding, the database would contain an int value that would determine which radiobutton was checked, and the database would also contain the text value for the textblock.
Any ideas or examples would be appreciated.

Hi GEB,
Please accept my apology for the delayed response.
I prepared a sample project illustrating a possible approach towards the described scenario. Please take a look at it and let me know if this is what you had in mind or if you need more info.

Thank you for the sample project. However, this only seems to solve half of the problem. How to change the value of the int when the RadioButton is checked by the user? The sample program sets the initial value to checked or unchecked, but does not seem to handle the two-way binding.

Hello GEB,
I modified the example by modifying the ConvertBack() method to return an approproate value when the user checks a button.
Please take a look at it and let me know if it works for you.

Thank you for the updated example. I did find an interesting timing issue. When a RadioButton is pressed, it causes two converters to be called for the same bound property. One converter is called because a radio button is unchecked, and the second converter is called because another radio button is simultaneously checked. Therefore, the bound property will be set to the value of the converter that is called last. In order to fix this issue, I changed the setter of the property to check for a value of 0. If 0, then setter ignores the value, and does not change the value of the property. If you can think of a better way to handle this condition, I'd love to hear it.

Hello GEB,
Changing the setter of the property to check for 0 value is a good solution.
