     comReg.ValueMember = "2";


     comPer.Items.Clear();
     switch (comReg.SelectedItem.ToString()) {
     case "Item 1":
             comPer.Items.AddRange(new string[]{"1", "2", "3", "4" });
     break;
     case "Item 2":
             comPer.Items.AddRange(new string[]{"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12"});

You're using DisplayMember[^] and ValueMember[^] properties wrong way.

In both cases the description is:

MSDN wrote:
A String specifying the name of an object property that is contained in the collection specified by the DataSource property. The default is an empty string ("").

So, to be able to use them, you need to set ListControl.DataSource Property (System.Windows.Forms) | Microsoft Docs[^]
