| Type | Default | Description |
|---|---|---|
| DevExpress.XtraEditors.SplitCollapsePanel | None | A SplitCollapsePanel enumeration value that specifies the panel automatically collapsed when clicking on a splitter. |
Remarks
To allow the first or second panel of the SplitContainerControl to be collapsed when clicking on a splitter, set the CollapsePanel property to SplitCollapsePanel.Panel1 or SplitCollapsePanel.Panel2. When a panel is collapsed, clicking on a splitter restores the panel to its original size.
The following image shows a SplitContainerControl with the CollapsePanel property set to SplitCollapsePanel.Panel2.
To prevent a panel from being collapsed/restored, you can handle the SplitContainerControl.SplitGroupPanelCollapsing event and set the event’s Cancel parameter to true. To respond to collapsing/restoring a panel, handle the SplitContainerControl.SplitGroupPanelCollapsed event.
To collapse/expand the panel in code, use the SplitContainerControl.Collapsed property.
