Page Controller

Let’s say in every page we need to get username and email ID, there are 2 ways we can do it. We could use file include (.inc files) or use page cotroller logic

SiteSettings has 2 properties, Name and Email ID. You can have your own logic to fetch information from database – may be use Table data gateway logic

SiteSettings.cs

using System;

using System.Data;

using System.Configuration;

///

/// Summary description for SiteSettings

///

public class SiteSettings

{

public SiteSettings()

{

}

private string _name;

public string Name

{

get { return _name; }

set { _name = value; }

}

private string _emailAddress;

public string EmailAddress

{

get { return _emailAddress; }

set { _emailAddress = value; }

}

#region Load functions

public void FetchData()

{

//implement your logic to fetch data from config file, DB or other datasources

_name = "xyz";

_emailAddress = "xyz@abc.com";

}

#endregion

}

Create a new BasePage class derived from System.Web.UI.Page. Create an event for ‘Init’ . In the event, load SiteSettings values

BasePage.cs

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

///

/// Summary description for BasePage

///

public class BasePage : Page

{

protected SiteSettings siteSettings;

public BasePage()

{

Init += new EventHandler(BasePage_Init);

}

void BasePage_Init(object sender, EventArgs e)

{

siteSettings = new SiteSettings();

siteSettings.FetchData();

}

}

Now that we have the base class let’s implement BasePage

Page1.cs

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

public partial class Page1 : BasePage

{

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

this.Load += new EventHandler(Page_Load);

}

//protected System.Web.UI.WebControls.Label pageNumber;

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

DisplaySettings();

}

pageNumber.Text = "2";

}

private void DisplaySettings()

{

eMail.Text = siteSettings.EmailAddress;

userName.Text = siteSettings.Name;

}

}
