Code to check when page has finished loading

Question

How can I check whether the page has finished loading? When it has, how can I execute a method already created in the C# code behind for that page?

I would like to orchestrate the following sequence of events

Finish Loading the page
Download a gridview as an Excel file in the page
Call this method download()
Close the browser

How can I accomplish this?

Just to confirm you want to have a popup window with an xls download pretty much? — Dave Walker, Dec 21 '11 at 09:31

Does this link answer your question?

Example usage (in your C# code)

protected void Page_Load(object sender, EventArgs e)
{
      Page.LoadComplete +=new EventHandler(Page_LoadComplete);
}

void  Page_LoadComplete(object sender, EventArgs e)
{
    // call your download function
}

i think so. but i dont know how to use that . confused – Dec 21 '11 at 09:45
thanks for the code. Looks like now there is something wrong with my code, as it still no data inside the downloaded data. (nvr show the nested gridview data) – Dec 21 '11 at 10:02
which is kinda weird though. i thought it should be 'okay' once the page has fully loaded. – Dec 21 '11 at 10:06
I'm sorry that will have to be another question. I've never done anything with Excel :( – Carl Winder Dec 21 '11 at 10:07

You don't need to add an event listener to Page.LoadComplete. Just like Page_Load event, it is being fired by the core. You just need to create the proper method with void Page_LoadComplete(object sender, EventArgs e) { //do something } – Roni Tovi May 05 '18 at 13:03

Use JQuery and make a callback to open the xls file.

There is a few solutions detailed here POST to server, receive PDF, deliver to user w/ jQuery

Basically you can hook into the

$(document).ready(function() {
  // do window.location or another one of the options to download the file.
});

seems like this is the way as it must be executed client side? – paulm Oct 07 '14 at 17:18

You can do it in DOM javascript:

window.onload = function() {
   download()
 }
