I am trying to cascade dropdowns using  ASP and VB

  

1st drop down     --> Sex Type
                                > Male
                                > Female
    2nd Drop Down    -->Status
                                > Orphan
                                > Married
                                > UnMarried
                                > Divorced
                                > Widow
                                > Special Need
                                > Normal

Now,  
If Male selected from 1st drop down, then select (Orphan, Special Need, Married, UnMarried,  Divorced, Widow and Normal) from 2nd Drop Down

And if Female selected from 1st drop down, then select (Orphan, Special Need and Normal) from 2nd Drop Down

I am getting data of drop dwons from database using Entities;

VB Code

    context As New EGrantsModel.Entities
    
    ddlSexType.DataSource = context.SEXTYPE
    ddlSexType.DataValueField = "SEXTYPE"
    ddlSexType.DataTextField = "SEXTYPE"
    ddlSexType.DataBind()
    
    ddlCitizenStatus.DataSource = context.CITIZENSTATUS
    ddlCitizenStatus.DataValueField = "CITIZENSTATUSID"
    ddlCitizenStatus.DataTextField = "CITIZENSTATUS"
    ddlCitizenStatus.DataBind()

ASP Code
 

 <div class="labelinput">
     <asp:Label ID="lblSexType" CssClass="lblwidth" runat="server" Text="">Sex Type</asp:Label>
     <asp:DropDownList ID="ddlSexType" runat="server"/>
       </div>
    
     <div class="labelinput">
       <asp:Label ID="lblCitizenStatus" CssClass="lblwidth" runat="server" Text="">Status</asp:Label>
        <asp:DropDownList ID="ddlCitizenStatus" runat="server"/>
         </div>

Can any one guide me in this regards. Thank you
