Thank you for contacting Telerik Support.
This layout can be achieved by adding a RadTreeView
with its DockStyle
set to Fill
, and a RadCollapsiblePanel
. You also will need to set its ExpandDirection
. You must keep in mind that due to the specifics of WinForms
layout you need to first add the RadTreeView
and then the RadCollapsiblePanel
Dock = DockStyle.Fill
Dock = DockStyle.Left,
ExpandDirection = RadDirection.Right
You can also refer to the attached project.
Do not hesitate to write back, should you have further questions.
