When you are creating ASP.net pages and content is build up from a DB, you'll probably work with usercontrols, placeholders ...
Recently I encountered another challenge. I was adding usercontrols to a placeholder to a page dynamically. The user controls have a save button which saved the data to the database. But then the parent page needed to be refreshed. I could do this by using a redirect to the page and it would be refreshed. But when data grows, a page refresh is less and less attractive. So I googled and came up with this solution: The OnBubbleEvent. If you want to read on what the event actually does, please google some more, I can show you a practical example.
Put this code on the page that calls holds the user control.
protected override bool OnBubbleEvent(object source, EventArgs args)
CommandEventArgs e = (CommandEventArgs)args;
if (e.CommandName == "Rebind")
When you finished the event (After you saved the data) on the user control, you can activate the bubble event!
CommandEventArgs args = new CommandEventArgs("Rebind", String.Empty);
So now, only the part we choose is refreshed. This way the asp stays light weight.
