 Here is the sample how you can do that.

1)  Add some JavaScript inside page header

{
	System.Web.UI.HtmlControls.HtmlGenericControl si = new System.Web.UI.HtmlControls.HtmlGenericControl();
	si.TagName ="script";
	si.Attributes.Add("type",@"text\javascript");
	si.InnerText = @"alert('I am in Head Element.')";
	this.Page.Header.Controls.Add(si);
}

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.

The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
