Hi,I'm sorting a TreeListView clicking the header. See the structure below. All the top rows are sorted fine (Ascending and Descending), A5 row have 1 child level and is sorted good too. But A1 that have more than 1 level of children doesn't work. If I keep A1 with 1 level of children (just F1 and A2) the sort works. So TreeListView support sort with more that 1 horizontal level of children ?

A1 - 0
          F1- 1
          A2 - 2

                    F2 - 3 

                     A3 - 4

                               A4 - 5
                               F3- 6
A5 - 7
           F4-8
           F5-9
F6-10
F7-11

This is my xaml:

 

<telerik:RadTreeListView Grid.Row="2" x:Name="DeckDataGrid"

Hello Omar,
 
I tested the behavior of the control we the latest assemblies version, as well with a couple of older ones. With all of them RadTreeListView sorted its items irrelevant to whether the child items on first level have child items or not. Attached to my reply you can find a sample application as a demonstration. Can you please check it out? Would it be possible for you to modify it so that the sorting malfunction is reproduced, open a new support thread and attached the modified sample in it? We would gladly assist you further.
 
Thank you in advance for your cooperation.


Regards,
Stefan
