I want to make a tree with same indentation in child level (i only need 2 level only), the child node i used as a hyperlink

usual tree :
+parent1

    -child1

    -child2

+parent2

    -child3

    -child4

i want to make it become

+parent1

-child1

-child2

+parent2

-child3

-child4

i'm using 2 version of infragistics 5.1 and 8.2, in version 5.1 the tree output without indentation (exactly what i want), but in 8.2 suddenly it change with indentation in each child node, i try to put indentation value with zero but still no result. do you have any idea what property or any way around to solve this

- thx for your attention -
