AJAX :: ERROR: The PageRequestManager Cannot Be Initialized More Than Once?
Nov 19, 2010
I'm loading a .aspx page via fancybox (ajax loading mode).I was using fancybox 1.2.6, working fine, then upgraded to fancybox 1.3.4 and IE now triggers the JS error above (in the subject of the post). Then why am I posting on ASP.net forum you might ask?!?... read on...Debugging the JS code, the error happens inside jQuery in the .html(data) function where it does a evalScript .each scripts inside data. jQuery version is 1.4.2.I'm able to resolve the problem by editing fancybox-1.3.4.js at line 265. I just use innerHTML to circuvent the evalScript that occurs inside html()... and it works:
//tmp.html( data ); <-- original code commented out where JS error occured
var tmpDiv = tmp.get(0); <-- new "plaster" kind-of fix
tmpDiv.innerHTML = data; <-- new "plaster" kind-of fix
Why I'm posting on ASP.net and not on jQuery nor fancybox groups is that I consider that the proper fix would be in the .aspx that is loaded via ajax.To summarize the problem. There is a base .aspx page that has a couples of text and buttons. When you click a button, it loads via AJAX a new .aspx page (using fancybox). You end up with two ScriptManager js code and it triggers an error when executing :
//<![CDATA[
Sys.WebForms.PageRequestManager._initialize('ctl00$ScriptManager', document.getElementById('aspnetForm'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);
[code]...

I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.

I have some Class A, which is data-layer in my web-application, and I'm using A's methods to accomplish Db operations. It looks like this.
[code]...
In case when my .aspx page calls 2 methods of class A during the postback, my page throws
"The ConnectionString property has not been initialized" exception for second method call.
I tried to put _sqlcon initialization into constructor, but it still throws exception.

I'm trying to use a DynamicPopulateExtender to add a product to the cart and then report back a success/failure-message to a div. After the request has finished, i'd also like to trigger an update of an UpdatePanel on the page. But there is a problem: To ensure that the div is visible only a short time after the request has finished, and to reload of the UpdatePanel, I need to know when the request has finished - and it seems that the DynamicPopulateControl for some reason doesn't trigger the PageRequestManager EndRequest-event. I've registered for the events with this code, and I've made sure that the code that registers the events run like it should. But neither CartBeginRequest nor CartEndRequest are ever called:
function pageLoad(sender, args){

I am getting above mentioned error when I try to run the following code:
Private strConnString As String = ConfigurationManager.ConnectionStrings("conString").ConnectionString
Private con As New SqlConnection(strConnString)
Private pID As Integer
'FIRST SECTION
Dim query As String = "query"
Dim cmd As New SqlCommand(query)
[Code] .....
The error is coming from the second SQL cmd but if I comment out the first section; the second section runs fine.
I must have made another basic error but I just can't figure out what it is.

How do I run a function associated with my custom control after it is initialized? So for example, after the control has initialized (ie is loaded) I need to finalize some properties. But since it is composed of a number of other controls, I need to know all the controls are present. I've tried add_load but I can't seem to get the context right to see my contol's specific functions. If I place the onLoad metod in the main class (javascript) definition, the contol id dosen't exist yet, same for in the prototype.
Since the control id dosen't exist yet I need to wait for the load event but now i'm in a chicken and egg problem. How do I create a method of my control class and call it "after" initilization? Seems like a simple question but it hasn't been so easy to find an answer.

How to remove all endRequest handlers in PageRequestManager?

When jQuery is applied to elements in an UpdatePanel, when the UpdatePanel refreshes, the jQuery is not applied to the newly injected HTML. This issue is resolved by using
Sys.WebForms.PageRequestManager.getInstance().add_endRequest() to register a function to be called when the AJAX request is complete: I've written a function that registers the function with add_endRequest, and also calls it at the same time:
Async.RegisterAndRun = function(callback) {
//register function to be run when an update panel request is complete
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(callback);
//also run the function right now.
callback();
};
Now all we need to call is Async.RegisterAndRun(AddFancyjQueryToMyHTML); or
Async.RegisterAndRun(function(){
AddFancyjQueryToMyHTML();
AddMoreFancyjQueryToMyHTML('with', 'args');
});
Currently it does what I need it to, and I never need to explicitly call add_endRequest which is nice.

In some posts I have read on other forums, those with database connection problems (I am thinking about Access) sometimes get the error: 'Connection property has not been initialized' which might translate as 'you have not kick-started your connection'. One reason for that, according to a number of replies I have come across, is that 'you have not set the connection property of the command object' ('you have not told command how to connect').
So would something like this:
Code:
Dim conn As New OleDbConnection
Dim OleDbConnection As New OleDbConnection
Dim cmd As New OleDbCommand
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|myDatabase.mdb;"
conn.Open()
cmd = New OleDbCommand("SELECT strName FROM school WHERE strName=@strName", conn)
cmd.Parameters.AddWithValue("@strName", UserName.Text)
cmd.Connection = conn
cmd.ExecuteNonQuery()
conn.Close()
a) initialise the connection property and b) set the connection property of the command object?

I have been looking through the event viewer on our server and can see quite a few people with this error but I can't replicate this myself but it is causing issues for people viewing our website is there anyway I can "initialize" Command Text property?
UPDATE
So I have this query
datelistquery = "SELECT DISTINCT property_id, ' - Sleeps ' + cast(number_slept as varchar) as combsleeps, number_slept FROM openquery ("+Application("hpbDsrc")+",'SELECT property_id, number_slept FROM web_details WHERE part_full_flag = ''F'' AND location = ''"&Session("TenChosenLocCode")&"'' AND property_id = ''"&Session("passedPropId")&"'' AND pets_yn like ''"&Session("TenPets")&"'' AND number_slept >= ''"&Session("TenAdults")&"'' AND year_week = ''"&Session("TenHolStDateHP1")&"'' AND on_hold = ''NO'' AND booked = ''NO'' ') ORDER BY number_slept, property_id"
So should I put at the start sqlCommand.CommandText(datelistquery) = "Select Distinct...."

I'm using jQuery tabs, which are initialized from a static .js file using a selector:
$()
.ready(function () {
$('.jqTabsStandard').tabs();
});
I'm using ASP.NET (not that it makes a difference I think), but when I click a button in one of the tabs, is there a way I can re-select that tab when the page reloads. I was thinking of sticking the tab section in an UpdatePanel. I was hoping there's a way I could trigger the tab to reselect.

Am I right in assuming that only after controls on Master page are merged into the control tree for the Page, can controls ( both those in Master page and in a content Page ) be initialized with their declarative values ( values set during design time)? b) If my above assumption is correct, then these controls cannot be initialized with their design-time values during Page.PreInit, since during Page.PreInit event stage we're still able to dynamically set a Master page?! So if that is the case, when are controls initialized with their declarative values? During Init event orâ€

I have an ASP.net control that contains a grid (protected member variable). Grid is populated from a function in the control. I have derived a new user control from this control without any control in it. I added additional functionality to populate grid and called base class function to do further operation on the grid. When I run my code, I get the null reference exception on grid object in the base control. I missing something in control inheritance? at what point do inner controls get created?
