2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

State Management :: Session Mode State Server - Sending Asynchronous Request
Nov 5, 2010Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.
SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}

State Management :: Custom Control: State Restoring For Controls Created With CreateChildControls
Dec 22, 2010Let me explain, describing the scenario:In a custom server control (in my case, derived from CompositeControl), in the overidden CreateChildControls method I create a complex tree of subcontrols, using information from a db.The db provides both information on which controls I need to create (the user interface's structure) and the data used to fill these controls.Than the user can interact with the control and change the data (that becomes different to what stored on db).
My custom control lives in the same page where there are other controls, obviously.And these controls can cause a postback at any time.What I need is that my custom control keeps the data entered by the user across these postback, without reverting to the original data and loose the user data entry.
Here is the first doubt:
1)I create the subcontrols dinamically in the CreateChildControls at any page refresh (both on first call than on postback).I know that the framework solves the reference between the posted data and the controls I create in the CreateChildControls in order to set properties and raise control events, but can you tell me when and how it actually does this? In which phase of page life cycle? What happens after the CreateChildControls?
A second doubt:2)If the user interface structure must change as a consequence of the data entered, I had to execute CreateChildControls twice (the first time to recreate the original interface to get the events and the second time to create the new interface)
In which phase of page/control lifecycle do I have to make the second call to CreateChildControls? I do it on Prerender now, but is it right or wrong, and why?
State Management :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode
Dec 12, 2010I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I checked the stack trace and its complaining about
[assembly: global::System.Data.Objects.DataClasses.EdmSchemaAttribute()]
[assembly: global::System.Data.Objects.DataClasses.EdmRelationshipAttribute("PoplarGroveModel", "tblMenuRole", "tblMenu", global::System.Data.Metadata.Edm.RelationshipMultiplicity.Many, typeof(PoplarGroveDataModel.Menu), "tblRole",
[Code].....
I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.
