There are a few ways to inject script to an ASP.NET page. Where to inject your script is depending on your need of the script on your page.
I am listing three ways to do it for one of my recent task:
1. If you want a startup type of javascript, you can use this syntax to inject the script to the end of the page just before the closing Form tag, you can use RegisterStartupScript:
Page.ClientScript.RegisterStartupScript( Me.[GetType](), “myScript”, sbOfTheScript.ToString())
2. If you want the script goes to the top of the page just after the Form tag, you can use RegisterClientScriptBlock:
Page.ClientScript.RegisterClientScriptBlock( Me.[GetType](), “myScript2″, sbOfTheScript.ToString())
3. If you want the script to be injected inside the Header part of your page, you can use a HtmlGenericControl to load a literal control for the script (Assume your Head tag’s id is “Head” and with a runat=”server” mark up):
Dim head As HtmlGenericControl = DirectCast(FindControl(“Head”), HtmlGenericControl)
head.Controls.Add(New LiteralControl(strOfYourScriptCode))
