Auto change the SizeMode property from a PictureBox

I have a list with these words { AutoSize,Normal,StretchImage,CenterImage,Zoom }

Firstly my users will select one item from the list and after i need to change the property SizeMode of my picture box as their selection.

Can i make something without use of if/switch-case statements ?

If (size_mode_list.SelectedText = "AutoSize") Then
    picture_box.SizeMode = PictureBoxSizeMode.AutoSize
ElseIf (size_mode_list.SelectedText = "Normal") Then
    picture_box.SizeMode = PictureBoxSizeMode.Normal
ElseIf (size_mode_list.SelectedText = "StretchImage") Then
    picture_box.SizeMode = PictureBoxSizeMode.StretchImage
ElseIf (size_mode_list.SelectedText = "CenterImage") Then
    picture_box.SizeMode = PictureBoxSizeMode.CenterImage
ElseIf (size_mode_list.SelectedText = "Zoom") Then
    picture_box.SizeMode = PictureBoxSizeMode.Zoom
End If

One way is to fill the CBO with the Enum names:

cbo.Items.AddRange([Enum].GetNames(GetType(PictureBoxSizeMode)))

Then parse the result:

pb.SizeMode = CType([Enum].Parse(GetType(PictureBoxSizeMode), cbo.Text), 
        PictureBoxSizeMode)

Use .Text or SelectedItem.ToString() and the cbo should be a DropDownList so the user cant type something in.

You could also write a small Name-ValuePair class to store the Name and Values to a List, then use the ValueMember property to set the size mode so you are working off the Enum Value rather than the Name.
