In web application accordion is a very nice using. By using that you can make you website good looking and in a small space you cam put many things. Here am giving you example of a dynamic Accordion which i am loading from a XML file.

To create that using AjaxControlToolkit. In AjaxControlToolkit a control named Accordion is available , i have just load this dynamically and reading data from XML.
Here are the coder to read data from XML and Load accordion dynamically

Accordion accordion = new Accordion();
accordion.ID = “AccordionID”;
accordion.SelectedIndex = 0;
accordion.FadeTransitions = true;
accordion.FramesPerSecond = 50;
accordion.TransitionDuration = 250;
accordion.SuppressHeaderPostbacks = true;
string _path = HttpContext.Current.Server.MapPath(@”Sitemap.xml”);
FileStream stream = new FileStream(_path, FileMode.Open , FileAccess.Read, FileShare.ReadWrite);
XmlDocument document = new XmlDocument();
document.Load(stream);
XmlNodeList nodeList = document.GetElementsByTagName(“Item”);
for (int i = 0; i < nodeList.Count; i++)
{
AccordionPane accorPane = new AccordionPane();
Label lbl = new Label();
lbl.ID = “lblControl”;
lbl.Text = nodeList[i].Attributes["name"].Value;
lbl.Width = 200;
lbl.BackColor = System.Drawing.Color.Wheat;
lbl.Style.Add(HtmlTextWriterStyle.MarginBottom, “3px”);
accorPane.HeaderContainer.Controls.Add(lbl);
for (int j = 0; j < nodeList[i].ChildNodes.Count; j++)
{
string name = nodeList[i].ChildNodes[j].Attributes["name"].Value;
Label lbl2 = new Label();
lbl2.ID = “lblControl2″;
lbl2.Text = name;
lbl2.Width = 195;
lbl2.BackColor = System.Drawing.Color.WhiteSmoke;
lbl2.Style.Add(HtmlTextWriterStyle.MarginBottom, “2px”);
lbl2.Style.Add(HtmlTextWriterStyle.PaddingLeft, “5px”);
HyperLink hl = new HyperLink();
accorPane.ContentContainer.Controls.Add(lbl2);
accorPane.ContentContainer.Controls.Add(new LiteralControl(“<br/>”));
}
accordion.Panes.Add(accorPane);
}
PlaceHolder1.Controls.Add(accordion);
stream.Close();

ASP.NET 3.5 introduces a new data binding control named the ListView. ASP.NET already has a lot data bind control; it should be more than 10. But the good news is, ListView can literally replace all other data binding controls in ASP.NET. ListView control makes data binding easier than previous controls. It has included styling with CSS, flexible pagination, and sorting, inserting, deleting, and updating features.

Advanced SEO for web developers

I saw a nice video today in MIX site this is about Search Engine Optimization. It’s a big video and I really learnt a lot about SEO after see that. You can also see that. Just download SEO video from here and enjoy.
I have written a brief on that video hope you can learn vey basic things from here too

1. Use HTML semantically
   • Example:
     Good: <H1>this is an Article</H1>
     Bad: <span class=”header1”> this is an Article</span>
     Because: Heading and title tag are more important to robot then span and JavaScript class.
     So be careful to use of common tags its priority sequence is like that <a>, <h1>, <title>, <Meta>, <table>
2. JavaScript and CSS

Retrieving Outlook Contact Lists using Javascript

Sometime we may need to import contact from client machine’s outlook, in this case we can write javascript to import outlook contacts easily. Here is the code how to do that.

var Const_olFolderContacts = 10;
var objApp = new ActiveXObject(“Outlook.Application”);
var objNS = objApp.GetNamespace(“MAPI”);
var colContacts = objNS.GetDefaultFolder(Const_olFolderContacts).Items
for( var i=1; i<=colContacts.count;i++)
{
 var v = colContacts.item(i);
 alert(v["FullName"]+” (“+v["Email1Address"]+”)”);
}

if this code does not works , please do the following so it should work

In Internet Explorer , go to Tools | Internet Options | Security  -> from ‘Custom Level’ go to ‘Initialize and script ActiveX controls not marked as safe for scripting’ and select ‘Prompt” — this should work now

have got a big detailes code here, you can check this too another code
