DockPosition.Fill = Invalid DockTabStrip for a DockPosition.Fill operation.

Trying to have a RadImageButton open a new form in a dock (Full mode not left/right/top/bottom)

    Private Sub RadImageButtonElement1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadImageButtonElement1.Click
        Form1.Close()
        Me.RadDock1.DockControl(Form1, DockPosition.Fill)
        Form1.Show()
    End Sub

If I change it to .Left it will work fine, but I want it to be Fill.  Also how do I check to see if the form/window is open so it doesnt keep openiing the window like the above code does.

Okay I used MDI insted and it fixed the issue.  But how do I make it so when another form is opened that tab becomes the focus?

    Private ExpediteWindow As Boolean = False
    Private HistoryWindow As Boolean = False

    Private Sub RadImageButtonElement1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadImageButtonElement1.Click
        If ExpediteWindow Then
            Return
        End If
        ExpediteWindow = True
        Form1.Text = "Expedite"
        Form1.MdiParent = Me
        Form1.Show()
        AddHandler Form1.Disposed, AddressOf ExpediteWindowClose
    End Sub

    Private Sub ExpediteWindowClose(ByVal sender As Object, ByVal e As System.EventArgs)
        ExpediteWindow = False
    End Sub

Hi bradley baker,

The answer to your first question is contained in the following article: Creating a RadDock at Runtime.

As to your second question, you can activate a window by its MDI form, when another form is shown, by using ActivateMdiChild method on DockWindowAdded:

Private f As Form2 = Nothing
Private form2Added As Boolean = False

Private Sub radButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
    If form2Added Then
        Return
    End If
    f = New Form2()
    f.BackColor = Color.Red
    f.MdiParent = Me
    f.Show()
    form2Added = True
End Sub

Private Sub radDock1_DockWindowAdded(ByVal sender As Object, ByVal e As DockWindowEventArgs) Handles RadDock1.DockWindowAdded
    Me.radDock1.ActivateMdiChild(f)
End Sub

In this example wont this only activate 1 form?  I have lots of forms.  Is there a way to just have it activate whatever form was last docked?

Hi bradley baker,

Thank you for the clarification. In order to activate each new window/form, please refer to the following code snippet:

Private Sub radDock1_DockWindowAdded(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.Docking.DockWindowEventArgs)
    Me.radDock1.ActivateWindow(e.DockWindow)
End Sub

If you have additional questions, feel free to contact me.
