[Zeng]

 public partial class FrmMain : Telerik.WinControls.UI.RadForm
    {
        DocumentContainer documentContainer = new DocumentContainer();
        public FrmMain()
        {
            InitializeComponent();
            this.IsMdiContainer = true;
            this.radDock1.AutoDetectMdiChildren = true;
            
            this.radDock1.MainDocumentContainer = documentContainer;
        }

        private void radButton1_Click(object sender, EventArgs e)
        {
            FrmLogin frm1 = new FrmLogin();
            frm1.MdiParent = this;
            frm1.Show();
            this.ActiveControl = frm1;
        }

        private void radButton2_Click(object sender, EventArgs e)
        {
            RadForm2 frm2 = new RadForm2();
            frm2.MdiParent = this;
            frm2.WindowState = FormWindowState.Maximized;
            frm2.Show();
            this.ActiveControl = frm2;
        }

Hi Zeng,

Thank you for contacting us.

There seems to be an issue with the attachment. It appears that because the filename of the image contains special characters, it cannot be found on our servers. Therefore, given just the sample code and the ticket title, I am not sure I understand your requirement.

If the case is that you need to dock the second form to the right, then you can get the form's HostWindow from its Parent property and use the DockWindow method of RadDock:

    public Form1()
    {
        InitializeComponent();
        this.IsMdiContainer = true;
        this.radDock1.AutoDetectMdiChildren = true;
    }

    private void radButton1_Click(object sender, EventArgs e)
    {
        Form frm1 = new Form() { Text = "Form 1" };
        frm1.MdiParent = this;
        frm1.Show();
        this.ActiveControl = frm1;

        HostWindow hw = frm1.Parent as HostWindow;

        if (hw != null)
        {
            this.radDock1.DockWindow(hw, DockPosition.Left);
        }
    }

    private void radButton2_Click(object sender, EventArgs e)
    {
        RadForm frm2 = new RadForm() { Text = "Form 2" };
        frm2.MdiParent = this;
        frm2.WindowState = FormWindowState.Maximized;
        frm2.Show();
        this.ActiveControl = frm2;
        HostWindow hw = frm2.Parent as HostWindow;

        if (hw != null)
        {
            this.radDock1.DockWindow(hw, DockPosition.Right);
        }
    }
}

If this is not the case, please provide a detailed description of your requirement and try to attach the picture with no special characters in the file name (you can rename it to a number-only string to make sure I am able to open it). Understanding the case will let me provide you with further support.

Let me know if I can assist you further.
