Thanks

try with RegisterStartupScript

E.g: 

 RegisterStartupScript("Msg1", "<script language='javascript'> alert('Hello World') </script>");

  • +1 because I didn't know about the existance of this short version compared to the ClientScriptManager.RegisterStartupScript method. Looks like it's the same as calling Page.ClientScript.RegisterStartupScript(Page, Page.GetType(), "key", "MyFunc();", true);, but much shorter, and more readable Commented Aug 13, 2010 at 6:43

You can use this,

Page.ClientScript.RegisterStartupScript(Page.GetType(), "script", 
 "urfunction()", true);

string script = "..." // your script here without <script> tags
ClientScript.ClientScript.RegisterStartupScript(GetType(), "key", script, true)

Also if you want to use it directly from the .aspx you can use jquery

$(document).ready( function() {
 //... your script here
});

  • You might want to replace RegisterClientScript with RegisterClientScriptBlock, since no RegisterClientScript method exists Commented Aug 13, 2010 at 6:44
