Hi,

I am working on a website where i am creating Horizontal Menus Dynamically
from database as per rights available to the user. I have several
UserControls. And the Menu control also brings UserControl's URL stored in
Database while Page load.

There is a TabContainer control below the Menu Control.

Now i want to add corresponding UserControl dynamically when user clicks on
any MenuItem. also want to load data while UserControl loaded.

Page PostBack is the enemy of all Web Developers... and so is mine..

I don't want to load already added userControls again, everytime the user
clicks any new MenuItem as when menuitem click start postback. The
Application is very much data driven, loading heavy data again and again
would not be the greatway to deal with.

Only the selected usercontrol should be added and it should not effect any
other things on page like Windows TabControl. Think like Windows TabControl
where we can switch between windows and we receive that previous tab in
status we left.

I know it's not at all a easy thing but it is possible..

The thing is when i am clicking any MenuItem ,corresponding TabControl
is getting added in TabContainer but TabContainer due to page Postback is
losing the last added Tab. Means it is showing only the Latest added Tab on
every menuItem click.

Then i tried keeping Menu Control in Update Panel so that whole page will
not refreshed. In this way it's not even adding any UserControl on
TabContainer. It is going with in the Eventhandler but seems to be like
update panel asynchronous postback is not happening. when i debugged this
then i got that everything is null. even UserControl object is also null
which MenuItem click is bringing from server side...

don't know exactly what's happening here..

Please pls pls help me... anyways thanks for all. Guys, waiting for
replies .

the current ms ajax library is not up to this. it counts on the update panel
(which is really a postback approach) for dynamic controls.

look at jquery, as it has the features you need. also the next ms ajax
library (at least the mvc version) is copying the concepts of jquery.
