Answer 1

<asp:DropDownList ClientIDMode="Static" ID="cmbState" runat="server" Width="130px" Height="30px" Font-Size="Small" Font-Bold="true" DataValueField="StateID" DataTextField="Name" AutoPostBack="True"></asp:DropDownList>

bool condition = true;
if (condition == true)
{
    cmbState.Enabled = false;
}

This should work unless you have something in your Page_Load method which would counter it.
The AutoPostBack property is important due to the order in which events are carried out on the page.
