Call a javascript function from c# static method

Question

I am using the below client script in aspx code behind to call a javascript function. But the below client script in public static method so i got the error in registerstartupscript first argument.My older post is here Call non-static function from static function

If any one have a possible solutions please post..

Page.ClientScript.RegisterStartupScript(typeof(Page), "SymbolError", "from_bill_tab();");

Are you trying to register a startup javascript in a [WebMethod] ? — mikey

I'm just looking at the other post you linked to, and it looks like your trying to do it in a [WebMethod] — mikey

yes [WebMethod] only allow the public static method. Am i right?. Thats why i need this type of client script to call a js function — user1951007

I don't think you can do this (register a script) from a static WebMethod in an aspx page. Is your intent to call your WebMethod from the aspx page via javascript/ajax? — mikey

Try this:

ClientScript.RegisterStartupScript(typeof(Page), "SymbolError", 
 "<script type='text/javascript'>alert('Error !!!');</script>");

I know this is an old question.I am answering this to help new users who come across this question.

To use clientscript inside a static method pass the Page object as a parameter to your static method

protected void Page_Load(object sender, EventArgs e)
        {
           LoadJavascript(Page);
        }



public static void LoadJavascript( Page page)
        {

           page.ClientScript.RegisterStartupScript(page.GetType(), "alert", "<script>alert('Hai');</script>");
        }

because the question is that we want to call the javascript through the static method not the load time. First read question carefully then after give the answer according to the question
