How to serialize or deserialize the docking state for a docked control on loading the application?
9 Dec 20191 minute to read
To serialize or deserialize the docking state, follow the below steps.
Before closing the docked/floating control, access the control’s parent and cast this to type Syncfusion.Windows.Forms.Tools.DockHost.
Syncfusion.Windows.Forms.Tools.DockHost dockHost = ctrl.Parent as Syncfusion.Windows.Forms.Tools.DockHost;
Dim dockHost As Syncfusion.Windows.Forms.Tools.DockHost = Me.listView1.Parent as Syncfusion.Windows.Forms.Tools.DockHost
- Access the DockHost’s InternalController and get its current serialization information through the GetSerCurrInfo() method.
Syncfusion.Windows.Forms.Tools.DockHostController dockHostController = dockHost.InternalController as Syncfusion.Windows.Forms.Tools.DockHostController;
Dim dockHostController As Syncfusion.Windows.Forms.Tools.DockHostController = dockHost.InternalController as Syncfusion.Windows.Forms.Tools.DockHostController
- This returns an object of type Syncfusion.Windows.Forms.Tools.DockInfo. The DockInfo.DockingStyle member gives the dock position of the control with respect to the host form and the DockInfo.rcDockArea.
Syncfusion.Windows.Forms.Tools.DockInfo dockInfo = dockHostController.GetSerCurrentDI();
Dim dockInfo As Syncfusion.Windows.Forms.Tools.DockInfo = dockHostController.GetSerCurrentDI()
- You can serialize this information against the control’s name, and later upon loading, appropriately use either the DockingManager.DockControl() / FloatControl() method based on the serialized DockingStyle and control’s bounds values, to set the control’s dock state.
