Solution 1

just try to rename your selection change method in code behind from DropDownList1_SelectedIndexChanged to ddlprocess_SelectedIndexChanged also the mark up as OnSelectedIndexChanged="ddlprocess_SelectedIndexChanged">

Hope this helps

Just add a dummy ListItem to the start of the DropDownList and set that item's Enabled property to false. i.e. <asp:ListItem Value="" Text="" Enabled="false" />
<asp:ListItem Value="1" Text="Item 1" />
