tnx for this info, Karl

but what happens when u have controls inside page, when are their events
processed, code inside .aspx pages and <%= %> tag, dynamicly added controls

 

[Karl Seguin [MVP]]

Events are recursive. If Page_Load fires in the page, then in the child
control, then in controls within the control.

<%= %> happens sometime after prerender

dynamically added controls play catch up when they are added to the page. If
they are added in Init, then init will fire. if they are added during
page_load, then init and page_load will fire...

great, IMHO you should write an article w/ this information

one last detail when are 'script runat=server' blocks in .aspx pages
executed - again after PreRender ?

Well, if I recall, you can't just do:

<script runat="server">
Response.Write("aa");
</script>

ur runat="server" needs to have hooks into the actual methods. so the
<script runat="server"> Page_Load</script> is the same event as the
codebehind one.
