vb functions evaluating on load

[Guest]

Hi there, I have created a vb server function which i want to evaluate when a server control button is clicked (only!) however it is evaluating the code on load even though i havent put it into the page_load function. why is it evaluating and not waiting for the calling click event? I have made it just plain sub. not private or anything FYI and have put it in the CBPage. thanks.

Can you share some code? Show us the code/event where the function is
called, etc.

This doesn't make too much sense...

Are you saying the Page_Load is run before your event handler is firing?
This is because ASP.NET needs to recreate the page before any event
handlers are fired.

ok i have a function in my aspx.vb code behind page called get_xml. it does some reading on an xml file and returns it to the browser. But i only want it to fire when a button is clicked so i have this on my aspx page:


<input type="button" id="getxmlbutton" onserverclick="get_xml" value="edit xml" runat="server">

and this function in my aspx.vb CB page

Sub get_xml(ByVal sender As System.Object, ByVal e As System.EventArgs)
blah blah
End Sub

my page_load is empty. But instead of this function waiting for the button to fire the event on the onserverclick, it runs it on load, so it goes and fetches xml before the user has even entered an xml file in a field. why is it running the function?

Forget about Page_Load. Your problem has nothing to do with Page_Load.
Page_Load is simply an event that happens, among many others. You have
defined a Sub that executes a certain functionality. Now, are you saying
that this Sub runs EVERY TIME the page is requested, regardles of PostBack
or any user events? If not, precisely what conditions cause this Sub to run?
Also, is there any code in the page, or in any of the controls in the page,
that calls this Sub?
