Group in Tree view

[Huzaifa]

I want to bind custom list of object to Tree view. Also want group the elements on some properties. Is there any way to add/create group in Treeview ?

for Example: 

i have List of class C1 that has Books, Authors, Title. I want to group the item first by Books, then Authors and then title, so Authors should be child of books and title should be child of Authors.

Please reply me.

regards,

Huzaifa

Hi Huzaifa,

Thank you for writing.

RadTreeView does not support grouping. Actually, we are not sure that we have seem such an implementation in a treeview. Have you used such a product before? If yes, could you share your experience with it?

We can nevertheless suggest to use RadGridView's hierarchy feature for this. Then you can group your objects on each level of the hierarchy.

HI,

Actually, i didn't find this in any control. Beside, I created my own custom Tree Control with Data binding. Actually my need was to group the object on specified fields, without multiple list and define relationship manually. 

Let me know, if you want any more info. Also, I think it would be good feature if you can provide this in future release.

Thank you for the valuable feedback.

This is indeed a nice feature for RadTreeView, we will consider implementing it in a future release.

Has this new feature been implemented?  This is an example of what I'm trying to do.  If I have a celebrity class and in the celebrity class I have child lists Movies, Albums.  My business object celebrity contains 2 lists, Movies and Albums.  I want to bind to those and allow the user to add remove edit celebrities, movies and albums.  From what I can see, the RadTreeView only supports having one child per node.

Using the RadGridView maybe my only option if it works there.

Hi , Scott,

Thank you for writing.

Your scenario is achievable in RadTreeView by using the Load on demand feature, where you will populate the tree manually. Thus, you can define the group nodes that you need by adding the desired groups.

You can also consider using a RadGridView, there you can use the Object Relational Binding functionality to display your hierarchical data. RadGridView supports grouping out-of-the-box.

I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
