Mdiform resizing occurs form docking error

Question

I'm using SplitContainer (It's contain two panels) control under my MdifForm.I'm using following code to showing my exist forms under SplitContainer panel2

   With My_Form
        .MdiParent = Me
        SplitContainer.Panel2.Controls.Add(My_Form)
        .My_Form_Activated(Me, e)
        .WindowState = FormWindowState.Maximized
        .Dock = DockStyle.Fill
        .Show()
    End With

Docking fill command work properly at first displaying of the My_Form. But after mdiform resizing, my_form size doesn't change. How can i fix this problem thanks.

Answer 1

do not use FormWindowState.Maximised. instead use FormWindowState.Normal and then rely on DockStyle.Fill.
