Have you tried with $(document).ready() ?

try this
Page.ClientScript.RegisterClientScriptBlock(typeof(ScriptManager), "CallMyMethod", "myMethod();");

Solution 3

Registers a startup script block for a control that is inside an UpdatePanel by using the ScriptManager control, and adds the script block to the page. and does NOT EXECUTE it.

http://msdn.microsoft.com/en-us/library/system.web.ui.scriptmanager.registerstartupscript.aspx[^]

To execute it you will need a client side event.. Not the server side Page_Load or anything

EDIT:

Check if this is your case

You might not seen the section function in first link.
RegisterStartupScript(Page, Type, String, String, Boolean) : Registers a startup script block for every asynchronous postback with the ScriptManager control and adds the script block to the page.

Check http://msdn.microsoft.com/en-us/library/bb310408.aspx[^]

I know that.. But the main question is whether the script EXECUTES ( CALLS, RUNS) or REGISTERS .. That is the main difference....No whether it is a page or control.. You should not be in too hurry to downvote...
