I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?

View 2 RepliesI have an asp.net page that is using and update panel and am including some javascript via a {script src=abc.js} tag. I have tried loading my javascript using both $(document).ready and $(window).load. Both fire on the initial load but fail to fire on an update panel postback.
Is there anything I can wire up client side that would fire regardless of the update panel? I know I can inject script server side but I ideally want to do this all client side and wire up what ever is needed the first time around.

How do we achieve this ?

ScriptManager.RegisterClientScriptBlock(this.updMainTable, typeof(string), "test1", "showRehabMain('"+val+"')", true);

I have a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..
Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.

View 13 RepliesI basically have an update panel being dynamically populated with a LinkButtons after a postback. This link buttons are being assigned an event. Now when I click the button the event is not firing. As I understand it the event is not firing because I'm not creating the button in the Page_Load event and therefore .Net does not remember this controls were created after postback. I'm not able to create these controls in the Page_Load as they are dependant on user input. So my question is how can I create these controls dynamically and have the page retain them and their events after postback?
