DockingManager throws System.ArgumentOutOfRangeException

[Aaron LeMasters]

I'm trying to dock several panels that I create at runtime but the exception below is thrown before the form shows.

Code:
m_ContentPanel = new Panel();
m_ContentPanel.Dock = DockStyle.Fill;

m_ContentPanel.Name = "ProvidersContentPanel";
m_DockingManager = new DockingManager();

m_DockingManager.ImageList = new ImageList();
m_DockingManager.ImageList.Images.Add(Properties.Resources.providers);
m_DockingManager.HostControl = Window;
m_DockingManager.HostForm = Window;
m_DockingManager.MaximizeButtonEnabled = false;
m_DockingManager.EnableContextMenu = false;


var panel = new Panel();
panel.Visible = false;
panel.Name = $"{Name}Panel";
panel.Dock = DockStyle.Fill;
m_DockingManager.SetEnableDocking(panel, true);
m_DockingManager.SetDockLabel(panel, Name);
m_DockingManager.SetDockIcon(panel, IconIndex);
m_DockingManager.SetCloseButtonVisibility(panel, false);
m_ContentPanel.Controls.Add(panel);


m_DockingManager.DockControl(panel, m_ContentPanel, DockingStyle.Fill, 500);

I see this code in all of your samples:

this.components = new System.ComponentModel.Container();

this.dockingManager1 = new Syncfusion.Windows.Forms.Tools.DockingManager(this.components);

but in my .NET application, this.components is always empty. I think this might be causing the exception.

Is this yet another compatibility issue with your platform and .NET?

Hi Aaron LeMasters, 

As the panel added to the DockingManager is again added to another panel, the issue occurs. We suggest you to use the panel to any of one element to avoid this Exception.
