+## Restore to current state

+When the `DockingManager` load a saved layout using the [LoadDockState](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Windows.Forms.Tools.DockingManager.html#Syncfusion_Windows_Forms_Tools_DockingManager_LoadDockState) method, the process may fail if an error occurs during deserialization. In such cases, the saved layout is not applied, and the current docking layout remains unchanged to ensure a consistent user experience.
+
+The LoadDockState method returns `true` when the layout is successfully loaded and applied. If loading fails, the method returns `false`, and no changes are made to the existing layout.
+
 ## Serialize dynamically added children
 
 By default, the docking manager cannot deserialize its saved layout properly, when its child collection is modified after the DockState is saved.

 ## Adding drop down item
 
 The [DropDownBarItem](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Windows.Forms.Tools.XPMenus.DropDownBarItem.html) is a type of bar item, which will display a popup menu when clicked. A custom control can also be loaded and displayed when the menu item is clicked. This can be done by assigning the required component to the [PopupControlContainer](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Windows.Forms.Tools.XPMenus.DropDownBarItem.html#Syncfusion_Windows_Forms_Tools_XPMenus_DropDownBarItem_PopupControlContainer) property of the drop down bar item.
