I'm trying to figure out how to simply pass data from pageload codebehind into an html page


what I was originally thinking was function, but that can't be in the pageload

but something like this

<MediaSource><%= GetMedia() %></MediaSource>

codebehind

Function GetMedia() as string

End function

But I think there's probably a better way of doing this

input greatly appreciated

I Noticed I could do this:

<%=Variable %>

then before pageload I can do

Public Variable as string = "test data"

but can't do that in the page load


hrmmm, literal might work

You can actually use <MediaSource><%= GetMedia() %></MediaSource>

just add this code in pageload

page.DataBind()

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.
