How to fire a code behind function when ASP.NET page is completely displayed?

Question

I need to trigger a C# code behind function right after an ASP.NET page is completely displayed.
Is there an event to program?
If not, do how to do it?

Answer 1

What you might want to try is Page Methods/WebMethods. Take a look at the tutorial on singingeels.com, basically it boils down to:

• Respond to the Sys.Application.load event to trigger a call back to the server to a page method
• Create a page method that contains the logic you wish to execute in response to the call
• Respond to the result sent back from the page method, as appropriate in an OnSucceeded/OnFailed event.

Answer 2

You can use the Page_PreRender event. This is called just before the Page is displayed.

Answer 3

Create a 'New Web Site' - the default website template comes with an example; the _Default class has the following:

protected void Page_Load(object sender, EventArgs e)
{

}

There are other events in the ASP.NET Page Life cycle which may be of interest to you. Hope this helps.

Answer 4

Try using this.

protected override void OnLoad(EventArgs e)
{
   base.OnLoad(e);
   // your code!
}
