.NET Forum / ASP.NET / General / July 2005Postback
I have a button which sets a vaiable in session. I retrieve the session the page load event. I seem to need to press the button twice for the variable to change (I am tracing it to see what the variable is). I am I misunderstanding something? The variable only seems to change further down the order of events. Any ideas . Cheers, Chris. Chris, chech out the lifecycle of the page. The button click event fires AFTER the page.Load event which is why your have to click your button twice. For a little background reading you might have a look at the following article: http://msdn.microsoft.com/asp.net/default.aspx?pull=/library/en-us/dnaspp/html/a spnet-pageobjectmodel.asp Regards Daniel Walzenbach >I have a button which sets a vaiable in session.

It's a little long winded to explain what I am doing. I want the button click to do something to an XML file before the page reloads. I now understand this is not how the postback process works. Is there any way of triggering the postback twice. I know its a hack..... > Chris, > > chech out the lifecycle of the page.
