Left Pane
Middle Pane
End Pane

This splitter has ResizeMode="EndPane" set.
Left Pane
Middle Pane
End Pane

This splitter has ResizeMode="Proportional" set.

Middle Pane
End Pane

This splitter has the ResizeStep property set to 20px to each of the SplitBars.
Left Pane
Middle Pane
End Pane

  • ResizeModes

    RadSplitter allows to define the way the panes are resized when a resizebar is dragged.
    Use the ResizeMode property of the RadSplitter object to define this behavior. There are 3 ResizeModes defined:
    • AdjacentPane - default - when this ResizeMode is used the panes that are in the left and right side (top/bottom respectively) of the resize bar will be affected only.
    • EndPane - only the End pane and the pane that is at the left(top) of the resize bar are affected
    • Proportional - all the panes that are positioned in the direction to which the resizebar is dragged will be affected. If the resizebar is dragged in the right direction all the panes that are on the right side of the resizebar will be affected. They will obtain a proportional size corresponding to their current size.
    The ResizeMode property also affects the way the panes are resized when a pane from the splitter is collapsed/expanded.
    You can use the ResizeStep property of the SplitBar to define the step in which the resize bars are snapped.
