is there anyway to register a .js file from code behind i n VB.net?
I know theres a way to do it using the

RegisterClientScriptBlock


any hints would be appreciated




The solution is simple, the problem is complex.

To register a js file, I think you would probably need a placeholder, and then just add a LiteralControl to it:

<asp:placeHolder id=plcScript runat=server />

dim script as string = "<script language=javascript src=YourFile.js></script>"
dim lc as new LiteralControl(script)
plcScript.Controls.Clear()
plcScript.Controls.Add(lc)

You've answered you own question here as RegisterClientScriptBlock is designed for the purpose. In reality all it actual does is render the string you pass as the script block to the HTML response immediately after the server FORM tag. You can use it to render any piece of HTML, a script block a link to an external script, a css file etc etc although it was intended for use with client scripts of course.
Code: 
string script = "<script language=javascript src=YourFile.js></script>"
Page.RegsisterClientScriptBlock("scriptid", script);

I like Pauls way but a little different, I'd use
a System.Web.UI.WebControls.Literal. I believe I got the Literal idea from CrazyBoyBert.

in the aspx inbetween the HEAD tags
<asp:Literal id="myJavaScript" text="myJs" runat="server"></asp:Literal>

the in the code behind
protected System.Web.UI.WebControls.Literal myJavaScript;

then to add the js you can
myJavaScript.Text="<script language=\"javascript\" src=\"YourFile.js\"></script>"

as CrazyboyBert stated RegisterClientScriptBlock puts it after the FORM tag and you will not be able to use <body onLoad="jsFunction();"> and in your code behind you will not be able to add attributes of functions that live in your js file.
Button1.Attributes.Add("onClick", "hello();");

Thanks guys
Thanks to you i just found out my problem
the javascript was calling the window.onload to populate a user control with data pulled from the database.

Its time for a better approach

Thank you very much
