Loading Async User Controls
I have a web page with multiple user controls which causes my page to load slowly. I've been trying to upgrade the page so that the main parts of the page loads then each user control loads seperatly in an async manner similar to what the mighty pageflakes.com does. I've been search for example on how to do this for the past 3 days, and keep coming up with nothing. Can somebody please point me into a direction or give me an example on how I can load my main page, then load each control in an async manner?
Thanks,
Brandon W.
Look at the AJAX frameworkhere. It'll be a lot easier if you're using web services to feed your data directly to the user controls, but you should be able to leverage the AJAX stuff to get the behavior you want.
Loading controls async
I have a control on the frontpage of my site that takes a long time to load, so I want the page to load normally, and then start loading the control asynchronously, so the user will be able to skip to another page if he doesnt want to see the control.
Is there anyway to accomplish this?
Tried with the updatepanel and a timer, and it executes fine, but I'm unable to stop the timer after it does the first Tick event.
The server side timer control has a bug that it cannot be stopped. There are few option like the one suggested in this thread.

Alternatively, you can just trigger the load of control in after Atlas finishes loading.

Loading multiple gridviews async
(probably a begginer issue) Here's my problem, I have 7 gridviews on a page... some of them are very long to load it takes about 30 seconds to load the page. I was wondering how to load them all async with the toolkit so that the users could at least see some of the gridviews before all the page gets loaded.
the Gridviews are all linked with a datasource, some SQL some objects.
Anybody have a clue?
thx.
Here is some code to setup what you need...<%@. Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="MultipleGridViewsAsync._Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"/> <div><asp:UpdatePanel ID="updatePanel1" runat="server" UpdateMode="Conditional"><ContentTemplate><asp:GridView ID="GridView1" runat="server"></asp:GridView></ContentTemplate><Triggers><asp:AsyncPostBackTrigger ControlID="loadGrids" EventName="click" /></Triggers></asp:UpdatePanel><asp:UpdatePanel ID="updatePanel2" runat="server" UpdateMode="Conditional"><ContentTemplate><asp:GridView ID="GridView2" runat="server"></asp:GridView></ContentTemplate><Triggers><asp:AsyncPostBackTrigger ControlID="loadGrids" EventName="click" /></Triggers></asp:UpdatePanel><asp:UpdatePanel ID="updatePanel3" runat="server" UpdateMode="Conditional"><ContentTemplate><asp:GridView ID="GridView3" runat="server"></asp:GridView></ContentTemplate><Triggers><asp:AsyncPostBackTrigger ControlID="loadGrids" EventName="click" /></Triggers></asp:UpdatePanel><asp:UpdatePanel ID="updatePanel4" runat="server" UpdateMode="Conditional"><ContentTemplate><asp:GridView ID="GridView4" runat="server"></asp:GridView></ContentTemplate><Triggers><asp:AsyncPostBackTrigger ControlID="loadGrids" EventName="click" /></Triggers></asp:UpdatePanel> <asp:Button ID="loadGrids" runat="server" Text="Load" /> </div> </form></body></html>
Steps:
1. Put each gridview within its own update panel
2. Create a AsyncPostBackTrigger that goes off a event
3. Create that event using javascript onload to fire the updates... (sorry don't have the code for that)
4. When that even is handled on the code behind bind each datasource to the grid
This way the page loads...
Then asks for the data...
Gets the individual grids...
Renders those grids...
Sorry that I can't help you with step 3, but this should work. Look into using the javascript function :
function __doPostBack(eventTarget, eventArgument)
Hope that works for you
Sorry for the delay of my reply, I was in vacation...
Thanks for the tip but it doesn't solve my issue, what happens is all my gridview loads together after the load of my page... I wanted each gridview to show as soon as they are ready...
any other idea or am I missing somethig obvious?
