Is There An Event That Occurs After Postback, But Before The Page Is Destroyed/recreated
May 3, 2010
My ASP.NET form contains a collection of dynamically-created radiobuttons that are created and configured in the Page_Load event handler.
Normally, I process postback data in the Page_Load handler, using the condition:
if (IsPostBack)
However, since the controls that I need to access are created IN the Page_Load handler, the postback data from the previous rendering of the page is lost. To better illustrate the problem, here is an outline of the events as they occur:
1-Page_Load is invoked for the first time
2-An unknown number of radiobuttons are created dynamically
3-The radiobuttons are configured, based on information present on the server
4-The radiobuttons are added to the page's content
5-The user selects an option, and clicks the submit button
6-The Page_Load handler is invoked for the second time
7-The radio-buttons are added dynamically, exactly as before
8-The radio-button that the user checked is seemingly non-existant for processing
It seems like I need to be processing different parts of this in different event handlers. Is there an event that occurs after postback, but while the original radiobuttons are still accessible?

I am using the timer inside UpdatePanel to check the time every second and enter it to a label control.
But I must ask, How this is going to effect performance? Bandwidth of the site?

I am new to asp.net, so this might be a basic question. But I am struggling on this for more time... I have loaded a COM object in Server script using code behind (C#) and that COM object will trigger events in some random interval. I need to update the client page whenever I receive an event from the COM object from server side (code behind).My question is, Is there a way to make the client page do postback from the code behind(C#)? ie., The client page needs to be updated whenever an event occurs in the server. Is that possible? The com event does not trigger a postback since it only occurs in the server and not in the client.

I'm trying to change a Label's text property and colour properties depending if an event occurs on the page behind file.
Does anyone have a similar issue?
if (((Label)FindControl("Label1")).Text != null) - //getting Object reference not set to an instance of an object.
{
Label Labelmerchantid = (Label)FindControl("Label1");
Labelmerchantid.Visible = true;
Labelmerchantid.ForeColor = System.Drawing.Color.Red;
}

I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box

I'm using the beta version of Visual Studio 2010. I'm running my ASP.NET 4.0 website through the debugger. Whenever there is a page load (e.g. clicking on a link, a postback) the session is ended and a new session is created. This wipes out all the session variables and makes debugging impossible. How to get session variables to persist across page loads?
Is this problem unique to running ASP.NET in a test environment or unique to the beta 2 version of VS 2010?

I have the following gridview inside an updatepanel that makes the bind from a datatable:
[Code]....
What I intend to do and I'm not getting is the following: When i edit a textbox in a row with a new value, like Desconto textbox, i want that when that textbox looses the focus, to refresh the gridview with new values that result from changes in the value of the textbox. It's a new bind as i know, the problem is how to find the correct way to trigger the textbox textchanged event, at the moment nothing is happening. I created the Desconto_TextChanged event but when compiling, i receive a compilation error:
Description: An error occurred during the compilation of a resource required to service this request. review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30456: 'Desconto_TextChanged' is not a member of 'ASP.index_aspx'.

I'm here again to share a problem that I'm fighting against for days. I'm developing an eCommerce Cart.
Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.
When the customer clicks over the Button, it fires a function that gets the content of the TextBox and do an update on my Database.
It works perfetly when it is done with the mouse click. But I need to fires the update function WHITHOUT the manually click event. When the customer just put the mouse out of the TextBox (onblur event), I want to fires that function.

I have alot of code in the page load event as below.
Is it best practice to use (!NotPostBack) and wrap the code in this block or does it depend on the methods etc. I also have code which populates ajax slideshow as well which gets images from database.

Consider I have 2 controls, C and CompositeC which contains C. Both C and CompositeC have ViewState.
Now consider a third control causes a postback.
The resulting life cycle will be as follow:
CompositeC tries to restore state. To do so it needs to create the child controls, so it creates C.
When C is created it's ViewState is restored.The third control's postback event is triggered. At this time a handler calls CompositeC.RecreatedChildControls() and C is created again.Everything renders.
The problem is that C state is not restored again after step 3. RecreateChildControls method should modify the control's state so that when C is reintroduced to the CompositeC control's collection it's viewstate is automatically restored but it doesn't.

I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)

I have used jQuery to invoke an AJAX webmethod in c#. This webmethod runs a query and stores the resulting information in a session variable. I have a gridview that has an objectdatasource that uses the session variable with the selectmethod to then populate the gridview with data from a query. I need the final piece to get the gridview to databind() again with the new value.
So click map, update gridview. However, maybe I'm going about this all wrong. In essence, take javascript variable, push to ASP.NET in C# and refresh gridview on page with new data from query.

When click on button, nothing happens - page does postback, refresh but event handler method is not executed. Generated HTML is bit strange. Every page control has correctly generated ClientID including parent container ID.

I'm having trouble with an image button I create via c# in an event causing page validation to occur on postback. The CausesValidation attribute is set to false at time of creation in the event. I also wire up the Click event in the page_init with postback so not to loose the event handler if the page posts another way. Here is the code I'm using in the click event of a Button. I've also tried to enable and disable viewstate for the button with no luck. What am I missing here that continues to fire page validation in the Click of this imagebutton?
