Property AutoCollapseSiblings
AutoCollapseSiblings
Indicates whether expanding this tree item should automatically collapse its sibling items. When enabled, the item enforces exclusive expansion behavior within its level in the hierarchy.
public virtual bool AutoCollapseSiblings { get; set; }
Property Value
Examples
If AutoCollapseSiblings is true, expanding
one item will collapse others at the same depth.
Remarks
This setting affects only user-driven interactions, such as clicks or keyboard expansion. Programmatic expansion through code is not affected and will not trigger sibling collapse.
