   Version 2
   <%@ Page Title="Account Group - Add" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="groupAdd.aspx.vb" Inherits="PFA.groupAdd" %>
   <asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <div class="form-group">
            <asp:Label runat="server" ID="lGroupCode" Text="Group Code" AssociatedControlID="eGroupCode"></asp:Label>
            <asp:TextBox runat="server" ID="eGroupCode" CssClass="form-control"></asp:TextBox>
        </div>
    </div>
</div>
<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <div class="form-group">
            <asp:Label runat="server" ID="lGroupType" Text="Group Type" AssociatedControlID="ddGroupType"></asp:Label>
            <asp:DropDownList runat="server" ID="ddGroupType" CssClass="form-control">
                <asp:ListItem Text="Incomes" Value="IN"></asp:ListItem>
                <asp:ListItem Text="Expenses" Value="EX"></asp:ListItem>
                <asp:ListItem Text="Assets" Value="AS"></asp:ListItem>
                <asp:ListItem Text="Liabilities" Value="LI"></asp:ListItem>
            </asp:DropDownList>
        </div>
    </div>
</div>
<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <div class="form-group">
            <asp:Label runat="server" ID="lGroupName" Text="Group Name" AssociatedControlID="eGroupName"></asp:Label>
            <asp:TextBox runat="server" ID="eGroupName" CssClass="form-control"></asp:TextBox>
        </div>
    </div>
</div>

And the result - the dropdown is still wider than the text boxes above and below.

enter image description here

Please see screenshot of rendered for below. Why does the dropdownlist occupy the whole screen width while the other two controls don't? Very new to web development. Please advice and help. Many thanks. Iyer

As Webruster says, you have specified a width of 100%. However, that's not the whole story. Even without this, Bootstrap will by default define a CSS width of 100%. Try wrapping the whole block in a <div class="col-***"> tag to better control sizes. For example, col-sm-3.

See the Bootstrap documentation for how to control form sizes.

EDIT: After chatting with the OP for a while, it transpired that the problem is with the Content/Site.css file that's automatically generated by Visual Studio when creating a new Web Forms app. Amongst other things, it contains the following style:

/* Set widths on the form inputs since otherwise they're 100% wide */ 
input[type="text"], 
input[type="password"], 
input[type="email"], 
input[type="tel"], 
input[type="select"]{ 
max-width: 280px; 
}

This is overriding the default Bootstrap behavior. Furthermore, there is not (as far as I'm aware) an input type called select. Asp.net dropdown lists render to normal select tags. So what the above style does is restrict the maximum width of several input tags, without affecting the dropdown lists.

There are two solutions. First, we can simply delete this block entirely. This will allow Bootstrap to behave as expected, as far as form elements are concerned. This would be my preference.

Second, replace input[type="select"] with simply select. If it transpires that my knowledge of input types is lacking, then add ", select" after it, rather than replacing it (don't forget the comma!)
