RadDock's SplitContainer does not fill the Windows

Question

I have the following code to create RadDock programmatically:

public void CreateDock(Control parent)
{
    RadDock dock = new RadDock();            

    DocumentContainer docContainerLeft = new DocumentContainer();
    docContainerLeft.SizeInfo.SizeMode = Telerik.WinControls.UI.Docking.SplitPanelSizeMode.Fill;
    DocumentTabStrip leftDocStrip = new DocumentTabStrip();
    DocumentWindow leftDoc = new DocumentWindow("Left");
    leftDocStrip.Controls.Add(leftDoc);
    docContainerLeft.Controls.Add(leftDocStrip);

    DocumentContainer docContainerRight = new DocumentContainer();
    docContainerRight.SizeInfo.SizeMode = Telerik.WinControls.UI.Docking.SplitPanelSizeMode.Fill;
    DocumentTabStrip rightDocStrip = new DocumentTabStrip();
    DocumentWindow rightDoc = new DocumentWindow("Right");
    rightDocStrip.Controls.Add(rightDoc);
    docContainerRight.Controls.Add(rightDocStrip);

    RadSplitContainer middleSplitter = new RadSplitContainer(Orientation.Vertical);
    middleSplitter.Dock = DockStyle.Fill;
    middleSplitter.SizeInfo.SizeMode = SplitPanelSizeMode.Fill;
    middleSplitter.Controls.Add(docContainerLeft);
    middleSplitter.Controls.Add(docContainerRight);

    dock.Controls.Add(middleSplitter);

    ToolWindow transferWindow = new ToolWindow();
    transferWindow.Text = "Transfer Queue";
    transferWindow.DockState = DockState.Docked;
    dock.DockWindow(transferWindow, DockPosition.Bottom);

    dock.Dock = DockStyle.Fill;
    parent.Controls.Add(dock);
}

I'm trying to make the middleSplitter to fit the window. However there is always an unwanted area at the bottom. I have a picture of it here but SO does not allow me to post an image.

My question is: How to avoid the unwanted area and make the Splitter fill the window?

The DockWindow method of RadDock might be of help in this case. Here is how you can achieve the desired look: DocumentWindow middleDoc = new DocumentWindow("Middle"); dock.AddDocument(middleDoc);

        DocumentWindow leftDoc = new DocumentWindow("Left");
        dock.DockWindow(leftDoc, middleDoc, DockPosition.Top);

        DocumentWindow rightDoc = new DocumentWindow("Right");
        dock.DockWindow(rightDoc, leftDoc, DockPosition.Right);

        ToolWindow transferWindow = new ToolWindow();
        transferWindow.Text = "Transfer Queue";
        transferWindow.DockState = DockState.Docked;
        dock.DockWindow(transferWindow, DockPosition.Bottom);
