Hi there,

After step 9, page 121 "Notice how the VB.NET code underscore is needed to split the code over two lines.VB.NET requires the underscore if you want to move the Handles keyword to its own line"

Which underscore it's refering to?

ListControls.aspx

Code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ListControls.aspx.vb" Inherits="Demos_ListControls" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>


        <asp:DropDownList ID="DropDownList1" runat="server">
            <asp:ListItem>C#</asp:ListItem>
            <asp:ListItem>Visual Basic</asp:ListItem>
            <asp:ListItem>CSS</asp:ListItem>
        </asp:DropDownList>

        <asp:CheckBoxList ID="CheckBoxList1" runat="server">
            <asp:ListItem>C#</asp:ListItem>
            <asp:ListItem>Visual Basic</asp:ListItem>
            <asp:ListItem>CSS</asp:ListItem>

        </asp:CheckBoxList>
    </div>
        
        <asp:Button ID="Button1" runat="server" Text="Button" />
&nbsp;
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
        
    </form>
    </body>
</html>

ListControls.aspx.vb

Code:

Partial Class Demos_ListControls
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

    End Sub

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Label1.Text = "In the DDL you selected " &
                              DropDownList1.SelectedValue & "<br />"


        For Each item As ListItem In CheckBoxList1.Items
            If item.Selected = True Then
                Label1.Text &= "In the CBL you selected " & item.Value & "<br />"
            End If
        Next
    End Sub
End Class

Help appreciated. Thks.

Cheers,
Mohamad
