Combo Box control in SOLIDWORKS property Manager Page

Combo box control will be automatically generated for all the properties of enumerator types. All values of enumerators will be considered as the items in the combo box:

Imports CodeStack.SwEx.Common.Attributes
Imports CodeStack.SwEx.My.Resources
Imports CodeStack.SwEx.PMPage.Attributes
Imports SolidWorks.Interop.swconst

Public Class ComboBoxDataModel

    Public Enum Options_e
        Option1
        Option2
        Option3
    End Enum

    <ComboBoxOptions(swPropMgrPageComboBoxStyle_e.swPropMgrPageComboBoxStyle_Sorted)>
    Public Property Options As Options_e

End Class

using CodeStack.SwEx.Common.Attributes;
using CodeStack.SwEx.PMPage.Attributes;
using CodeStack.SwEx.Properties;
using SolidWorks.Interop.swconst;

public class ComboBoxDataModel
{
    public enum Options_e
    {
        Option1,
        Option2,
        Option3
    }

    [ComboBoxOptions(swPropMgrPageComboBoxStyle_e.swPropMgrPageComboBoxStyle_Sorted)]
    public Options_e Options { get; set; }
}

Additional options and style for combo box control can be specified via ComboBoxOptionsAttribute
