Introduction

An Assembly is the building block of a .net application. It is a self describing collection of code, resources, metadata. An Assembly is a compiled and versioned collection of code and metadata that forms an atomic functional unit. Assembly takes the form of a Dynamic Link Library (.dll) or Executable program file (.exe) but they differ as they contain the information found in a type library and the information about everything else needed to use an application or component.


Steps for creating an assembly

  • Create a (web/windows/console/class Library) project in vs.net. 
  • Then add your code as we add below. 
  • Add the below code in your Default.aspx page.

    <%@ Page Title="Home Page" Language="vb" AutoEventWireup="false"
        CodeBehind="Default.aspx.vb" Inherits="bulletedlist._Default" %>
       
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <
    html xmlns="http://www.w3.org/1999/xhtml">
    <
    head id="Head1" runat="server">
        <title>How to Use BulletedList and Bullet Style Property</title>
    </
    head>
    <
    body>
        <form id="form1" runat="server">
        <div style="width: 478px">   
           
    <asp:BulletedList ID="BulletedList1" runat="server">
                <asp:ListItem>Lesson 1</asp:ListItem>
                <asp:ListItem>Lesson 2</asp:ListItem>
                <asp:ListItem>Lesson 3</asp:ListItem>
                <asp:ListItem>Lesson 4</asp:ListItem>
                <asp:ListItem>Lesson 5</asp:ListItem>
            </asp:BulletedList>
            <br />
            Bullet Style<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
                <asp:ListItem>Numbered</asp:ListItem>
                <asp:ListItem>Circle</asp:ListItem>
                <asp:ListItem>Square</asp:ListItem>
                <asp:ListItem>LowerRoman</asp:ListItem>
                <asp:ListItem>UpperAlpha</asp:ListItem>
                <asp:ListItem>UpperRoman</asp:ListItem>
            </asp:DropDownList>
            <br />
        </div>
        </form>
    </
    body>
    </
    html>
     
  • Then write the code for the code behind file.

       
    Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles
        DropDownList1.SelectedIndexChanged
           
    If DropDownList1.Text = "Numbered" Then
                BulletedList1.BulletStyle = BulletStyle.Numbered
           
    ElseIf DropDownList1.Text = "Circle" Then
                BulletedList1.BulletStyle = BulletStyle.Circle
           
    ElseIf DropDownList1.Text = "Square" Then
                BulletedList1.BulletStyle = BulletStyle.Square
           
    ElseIf DropDownList1.Text = "LowerRoman" Then
                BulletedList1.BulletStyle = BulletStyle.LowerRoman
           
    ElseIf DropDownList1.Text = "UpperAlpha" Then
                BulletedList1.BulletStyle = BulletStyle.UpperAlpha
           
    ElseIf DropDownList1.Text = "UpperRoman" Then
                BulletedList1.BulletStyle = BulletStyle.UpperRoman
           
    End If
        End Sub
     
  • Now compile your application by choosing Build from the menu. 
  • When you build the application you will find a bin directory under your Root directory. The bin directory will contain a(.dll file )this .dll file is called the ASSEMBLY.

    You can see the assembly in assembly.zip attachment.
