How to use ImageMap Control in ASP.NET

Introduction

An image map is a picture on a webpage that provides various links , called hotspots, to navigate to other web pages , depending on the place where the user click (on single image). Web Designer frequently use image maps in their websites . An image map can be included in your web page by using the ImageMap Control.

An ImageMap control exists within the System.Web.UI.WebControls namespace. Image maps are often real maps; for example , you can display the map of the USA and define hotspot regions for each of its state and then navigate to the corresponding page containing the information for the selected state.

Public Properties of the ImageMap Class
Enable : Obtains or sets a value indicating whether the control can respond to user interaction.

HotSpotMode : Obtains or sets the default behavior for the HotSpot objects of an ImageMap control when the HotSpot objects are clicked.

HotSpots : Obtains or sets a group of HotSpot objects that represents the defined hotspot regions in an ImageMap Control.

Target : Obtains or sets the target window to show the Web page content when the ImageMap control is clicked.

Public Event of the ImageMap Class
Click : Occurs when a HotSpot object in an ImageMap control is clicked.

SELECT DepartmentID ,Name ,Description From [Table] ;

RETURN 0

Step-4: Take a webform in your project name as "Departmentlist.aspx"

Step-5: Paste this code into your Department.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Departmentlist.aspx.cs" Inherits="Departmentlist" %>

<!DOCTYPE html>

</head>

<body>

<asp:DataList ID="DataList1" runat="server">

Choose a Department

</HeaderTemplate>

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl ='<%#Link .ToDepartment (Eval ("DepartmentID").ToString ()) %>'

Text ='<%# HttpUtility .HtmlEncode (Eval ("Name").ToString ()) %>' ToolTip ='<%# HttpUtility .HtmlEncode (Eval ("Description").ToString ()) %>' >

</asp:HyperLink>

</ItemTemplate>

</asp:DataList>

<div>

</div>

</form>

</body>

</html>

Step-6: Paste this code into your codebehind file

using System;
using System.Data.SqlClient;
using System.Data;

public partial class Departmentlist : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection();
con.ConnectionString = @"Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True";
con.Open ();
SqlCommand cmd=new SqlCommand ();
cmd.CommandText ="GetDepartments";
cmd.CommandType =CommandType .StoredProcedure ;
cmd.Connection =con;
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds, "Department");
DataList1.DataSource = ds;
DataList1.DataBind();

}
}

Step-7 Make a Link class for absolute url

using System;
using System.Web;

/// <summary>
/// Summary description for Link
/// </summary>
public class Link
{
public static string BuildAbsolute(string relativeuri)
{
// get current uri
Uri uri = HttpContext.Current.Request.Url;
// build absolute path
string app = HttpContext.Current.Request.ApplicationPath;
if (!app.EndsWith("/"))

app += "/";
relativeuri = relativeuri.TrimStart('/');
// return the absolute path
return HttpUtility .UrlPathEncode (String .Format ("http://{0}:{1}{2}",uri .Host ,uri.Port ,app ));

}
public static string ToDepartment(string departmentId, string page)
{
if (page == "1")

return BuildAbsolute(string.Format("catalog.aspx?DepartmentID={0}", departmentId));
else
return BuildAbsolute (string .Format ("catalog.aspx?DepartmentID={0}&Page={1}",departmentId,page ));

}
//generate a department url for the first page
public static string ToDepartment(string departmentId)
{
return ToDepartment(departmentId, "1");
}

}

Windows Forms

May 14, 2016

Windows Forms Events

An event is generated when a user performs an action, such as clicking the mouse or pressing a key. When a user clicks a form, the clicks event is generated for the form.
Each form and control has a predefined set of events associated with it. You can instruct an application to perform a specific action when an event takes place. For example, you can write code for adding items to a list as soon as a form is loaded.

Click : Occurs when a user clicks anywhere on a form.
DoubleClick : Occurs when the component is double-clicked.
FormClosed : Occurs when a form is closed.
Deactivate : Occurs when a form losses focus and is no longer active.
Load : Occurs when a form is loaded in the memory for the first time. This event can be used to initialize variables used in a form. This event can also be used to specify the initial values to be displayed in various controls in a form.
MouseMove : Occurs when a mouse is moved over a form.
MouseDown : Occurs when the left mouse button is pressed on a form.
MouseUp : Occurs when the mouse button is released.

You can specify the action to be performed on the occurrence of an event within a special method called, event handler. You can add code for an event handler by using the code Editor window.

To write code for an event corresponding to an object, open the properties window for that object.
