Hello Richard, Jaehong,

I have to contradict you on this, if you call radDock1.ActiveWindow.FindForm() it will return the parent form, please see the following example:

Imports System

Imports System.Windows.Forms

Imports Telerik.WinControls.UI

Imports Telerik.WinControls.UI.Docking

Partial Public Class Form1

Inherits Form

Private WithEvents radDock1 As New RadDock()

Private WithEvents CreateFormButton As New RadButton

Private WithEvents GetActiveFormButton As New RadButton

Public Sub New()

InitializeComponent()

End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Me.IsMdiContainer = True

radDock1.AutoDetectMdiChildren = True

Me.radDock1.MdiChildrenDockType = Telerik.WinControls.UI.Docking.DockType.Document

radDock1.Dock = DockStyle.Fill

Me.Controls.Add(radDock1)

CreateFormButton.Text = "Create Form"

CreateFormButton.Dock = DockStyle.Bottom

Me.Controls.Add(CreateFormButton)

GetActiveFormButton.Text = "Get Active Form"

GetActiveFormButton.Dock = DockStyle.Bottom

Me.Controls.Add(GetActiveFormButton)

End Sub

Private Sub getActiveFormButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles GetActiveFormButton.Click

Dim activeForm = DirectCast(radDock1.DocumentManager.ActiveDocument, Telerik.WinControls.UI.Docking.HostWindow).MdiChild

Dim form = radDock1.ActiveWindow.FindForm()

If (Not activeForm.Equals(form)) Then

MessageBox.Show("Child form is: " + activeForm.Name+ " Parent form is: "+form.Name)

End If

End Sub

Private Sub button_Click(ByVal sender As Object, ByVal e As EventArgs) Handles CreateFormButton.Click

Dim form = New ChildForm()

form.Name = "ChildForm " + radDock1.DockWindows.Count.ToString

form.Text = "ChildForm " + radDock1.DockWindows.Count.ToString

form.MdiParent = Me

radDock1.ActivateMdiChild(form)

form.Show()

End Sub

End Class

Public Class ChildForm

Inherits Form

Public Sub New()

InitializeComponent()

End Sub

''' <summary>

''' Required designer variable.

''' </summary>

Private components As System.ComponentModel.IContainer

''' <summary>

''' Clean up any resources being used.

''' </summary>

''' <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>

Protected Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing AndAlso (components IsNot Nothing) Then

components.Dispose()

End If

MyBase.Dispose(disposing)

End Sub

#Region "Windows Form Designer generated code"

''' <summary>

''' Required method for Designer support - do not modify

''' the contents of this method with the code editor.

''' </summary>

Private Sub InitializeComponent()

Me.components = New System.ComponentModel.Container()

Me.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font

Me.Text = "Form1"

End Sub

#End Region

End Class

If you have any other questions or comments, please let me know,

Hello, Cesar,

I have used the same code in my sample project with the latest version of the Telerik UI for WinForms suite. Is the issue reproducible in the sample project that was provided in my previous reply? Could you please specify what is the version you are using on your end since I suppose that it is not 2019.2.618?

I am looking forward to your reply.

Hello, Cesar,

In order to run the application, it is necessary to use the references from the version you have installed on your machine. You can remove all references and add them anew by using the DLLs from your installation. Delete the license.licx file. After that, you should rebuild your project, close Visual Studio and open it again to make sure that no references are kept in the memory by Visual Studio.

Then, you are expected to run the application without any issues. I have already tested it on my end and it seems to work as expected.

I hope this information helps.
