Splitter / Locked Panes

The middle pane has the Locked property set to true. Try to resize/collapse the sibling panes to see how they behave.

Left Pane
Middle Pane (Locked)
End Pane


  • Locked Panes

    Use the Locked property of a RadPane to lock the pane.
    When a pane is locked its size remains unchanged during any of the operations including:
    • Resize of the splitter
    • Resize of the panes regardles of the ResizeMode
    • Collapse / Expand of the panes
    The size of a locked pane can be changed only from the client-side API when using the SetWidth or SetHeight methods of RadPane.
