How to add a MDI Child from another MDI child?

Platform: WinForms |
Control: TabbedMDIManager |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


For doing this the MdiParent property for the new child has to be set from another child form. Please refer the below code snippet which illustrates this:


private void buttonAdv1_Click(object sender, EventArgs e)


Form3 child1 = new Form3();

// Set the new form's MDI parent to main form

child1.MdiParent = (Form1)this.Parent.Parent;

child1.Text = "Document";




Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim f1 As Form3 = New Form3()

' Set the new form's MDI parent to main form

f1.MdiParent = CType(Me.Parent.Parent, Form1)

f1.Text = "Document"


End Sub
