Resizing RadGridView

Hi there,

I have a UserControl which I load into a form.
On this control is a RadGridView.

Unfortunately, the automatic cell resizing does not work.
Only the heading is resized.
Can someone help me?
Thanks Udo
Here is my code to load the UserControl

        Dim _objektdaten As New VB_Feuerbeschau.objekte
        _objektdaten = CType(Controls("ucObjekte"), objekte)
        If _objektdaten Is Nothing Then
            _objektdaten = New objekte()
            _objektdaten.Name = "ucObjekte"
            Me.Controls.Add(_objektdaten)
            _objektdaten.Dock = DockStyle.Fill
            _objektdaten.BringToFront()
           
        Else
            _objektdaten.Dispose()
            _objektdaten = Nothing
            _objektdaten = New objekte()
            _objektdaten.Name = "ucObjekte"
            Me.Controls.Add(_objektdaten)
            _objektdaten.Dock = DockStyle.Fill
            _objektdaten.BringToFront()

           
            '_objektdaten.rgvObjektdaten1.BestFitColumns(BestFitColumnMode.AllCells)
            For Each column As GridViewDataColumn In _objektdaten.rgvObjektdaten1.Columns
                column.BestFit()
            Next

        End If
