Nested WinForms open in RadDocument Host Window

[Satyajeet B]

Hi there,

I am using Rad dock in my application to open existing winforms using below code. On click of RadMenuButtonItem an existing WinForm opens in a NewDocument(HostWindow).

objForm=

New Form
Dim hostWindow As HostWindow = RadDock1.DockControl(objForm, DockPosition.Right)

 

objForm.Dock = DockStyle.None

hostWindow.AutoScroll =

True

 

RadDock1.AddDocument((hostWindow), DockPosition.Fill)

hostWindow.ScrollControlIntoView(hostWindow)

objForm.Show()

This works fine. 
Now the form opened in the host window has a button, on click of that button again an existing form should open in a new RadDocument Host Window. In the button click event i am creating an object of that form and just calling Obj.Show() which opens the form normally. Can anyone please assist how can i open the second form in Host Window aswell.

Thanks

Hi Satyajeet B,

Here is a sample implementation of the form that contains the button:

Public Class Form2
    Dim hostParent As HostWindow

    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        hostParent = Me.Parent
    End Sub

    Private Sub RadButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadButton1.Click
        If hostParent IsNot Nothing Then
            Dim f3 As Form3 = New Form3
            hostParent.DockManager.DockControl(f3, DockPosition.Left, DockType.Document)
        End If
    End Sub
End Class

As you can see, I am simply getting the parent of the form which is the HostWindow that hosts the form. I can get the RadDock control by the DockManager property of the HostWindow. Next, I just need to create an instance of the second form and dock it with the help of the DockControl method.

I hope this helps. If you have additional questions, feel free to contact me.
