Updateprogress on page_load ?

I have a long running process that might take several seconds to populate a control. Id like to show a progress indicator while this is being done. Anyone got an example of showing an updateprogress during page_load ? Maybe I can just use javascript to invoke a button click event on a non-visible button and have it start off the process ?

 here's a quick example:

var $user_updateProgress=Sys.Application.findComponent('ctl00_WorkingArea_Container_User_list1_UserLookupProgress');

 I had an UpdateProgress control named UserLookupProgress which I wanted to display. When the page loads, the control gets loaded into a javascript Sys.UI.Control.
So I needed to access it and it was driving me nuts! so I took a look at the source and figured out how they were doing it. Ultimately you need to use the findComponent method
of the Sys.Application class. The thing I could not figure out is why I had to reference the fully qualified ClientID in order to gain reference to my control.

From there I was able to show/hide the control.

 Hope this helps.

 P.S. if anyone has a better way , PLEASE chime in ;)

I want to show a updateprogress while my page loads. There is a tree that is populated with a large amount of data.

i have encounter same problem b4, that need to load a large data on the page load

but the interface will hang untill all the data was process.

i did a silly job to solve this problem

add a timer that run only once, set it to false by default, then on pageload and Ispostback=false, enable the timer run only once.

in the timer tick event bind the data.

thus, the databind is start after page load, and updateprogress working in this way too.

UpdateProgress Template and the Control Toolkit

I have an

atlas:UpdateProgress Template on the same page as some cascading drop downs. I have put in a large (5 seconds) delay on the webservice populating the dropdowns but still don't see the ProgressTemplate.

Does the UpdateProgress Template work with the control toolkit or is it just for UpdatePanels?

The Toolkit controls do not natively work with Atlas's UpdateProgress control. I looked into this briefly just now and it doesn't seem like the UpdateProgress control can be used in this way. Rather, it seems to tie itself directly to the "in postback" status of the relevant page. Since there are no postbacks in the CascadingDropDown scenario, UpdateProgress doesn't seem relevant. Sorry about that!

Updating one updatepanle data from other updatepanel

I have a september ctp atlas dll. We have one updatepanel with timer which fires every 5 seconds & get application variable data from server.In second updatepanel we have a treeview which we want to update only if value in application variable changes.If we put timer in treeview updatepanel then treeview refreshes with images,nodes which we do not want.Can we add nodes in treeview from another updatepanel.Unfortunately, the treeview is not yet supported (as well as some other databound controls that use templates)...There are some hacks you can try in the meantime...for instance the gridview when template is not supposed to be supported but I have managed to get it to work by using a combinations of controls...another good post to read is this...
