Question

I have an ascx control that is loaded in an aspx page.
How can I instruct my ascx to run javascript once it is rendered in the browser.
It should run on every postback as well.

I looked around but could not find a satisfactory answer.

Answer 1

Have you tried using the “RegisterStartupScript” method along with JQuery to call a JS function?
This code might help you:

ScriptManager.RegisterStartupScript(Page, GetType(Page), "myScript", "$(function() {{ alert ('Your page is loaded.'); }});", True)

You can replace the alert with any JS function you want 🙂

I hope this helps.
