C# bind dropdown to enum

For example we have enumeration Enum1 and want to bind ddEnum1.
here is how to do it in directly into html page , when GetEnum1 is function in codebehing , that will be getting SelectedValue for every record object (passign by parameter)

     
<asp:TemplateField HeaderText="Type" ItemStyle-Width="5%" ItemStyle-Wrap=False HeaderStyle-HorizontalAlign=Center HeaderStyle-Wrap=False ItemStyle-HorizontalAlign=Center>
	<ItemTemplate>
				  <asp:DropDownList id="typeDropDown" runat="server" Width='150'
					DataSource="<%# Enum.GetNames(typeof(myEnum1)) %>"
					SelectedValue='<%# GetEnum1(Container.DataItem) %>'
					OnInit="InitDropDown" />

	</ItemTemplate>
</asp:TemplateField>

here is how to do it in codebehind

       
    private void Page_Load(object sender, System.EventArgs e)
    {
         if(!IsPostBack)
         {
            ddEnum1.DataSource = Enum.GetNames(typeof(Enum1));
            ddEnum1.DataBind();
         }
    }

      private void ddEnum1_SelectedIndexChanged(object sender, System.EventArgs e)
      {
       Enum1 selectedEnum1 = (Enum1)Enum.Parse(ddEnum1.SelectedValue);
      }
