    How can I load one instance of a form to the tabbed document list? I am current running this code.
        Private Sub newMDIRadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newMDIRadButton.Click
            Form5.MdiParent = Me
        End Sub
    but if I close the document from the tab and try to load it again, it doesn't work. Also, if I click the button one more time while the form5 loaded, it disappears.

    Hello Ren,

    When Form5 is loaded for the first time, the DocumentPane wrapper is created (Parent for Form5) and registered with the DockingManager. When Form5 is closed from the DockingManager, then only the parent (DocumentPane) is unregistered from the DockingManager. In this situation you may use the following code snippet:

    if (form.Parent == null)  
        form.MdiParent = this;  

    If you need any further assistance, please contact us.

    All the best,

    FYI, I was running into this situation earlier today when I came across the following article,


    I then changed the following code

    foreach (Form frm in this.MdiChildren) 

    to this

    foreach (Form f in dockingManager1.MdiChildren) 

    and everything works well.

    I hope this helps.
