I've been working on this site on VS Studio for Web 2012. Most of it is HTML and ASP, but I've included a DayPilot calendar that I downloaded from SourceForge. I, apparently, must DataBind the calendar to my SQL server, so that users can login and set aside times for themselves on the calendar. I've used just about every recommended code I can find on the Net, but none seem to work on the Calendar page.
Here is the aspx page and the aspx.vb page codes:

If any of that makes sense, or you see where I'm going wrong, please share or correct my coding. Thank you!
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DayPilotCalendar1.DataSource = getData()
DataBind()
End Sub
This need to be
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DayPilotCalendar1.DataSource = getData()
DayPilotCalendar1.DataBind()
End Sub
Can we see the Databind function that is called by PageLoad?
I had an issue similar to this when I was working on a C# asp.net application. I created a method to bind the data from a dataset that contained a table of cards. When loading the table "NullReferenceException was unhandled by user code" was thrown and upon looking at the table I could see that a null value was being held.
When you are debugging and the exception is thrown, what is being shown as the held value of the data table?
If it is null then your table is not referring to an object.

When a video request is handled by the HTTP Module (code below) such as /website/uploads/Video/M2U00001_2.mp4 the _context.User is null.
When I run this in VS2010 on my local machine using the Visual Studio Development server _context.User is set. After I deploy to IIS 7 (.net 4.0) _context.User is Null.
'_context.User' is not Null when the http module processes an aspx page but it is Null when processing javascript, images, videos or CSS.
Can anyone explain why _context.User is null and possible solutions that will ensure _context.User is not null.
public Class VideoSecurityModule
Implements IHttpModule
Private WithEvents _context As HttpApplication
Public Sub Dispose() Implements IHttpModule.Dispose
End Sub
Dim myUserManager As UserManager
Public Sub Init(ByVal context As HttpApplication) Implements IHttpModule.Init
_context = context
myUserManager = New UserManager
End Sub
Public Sub OnAuthorizeRequest(ByVal source As Object, ByVal e As EventArgs) Handles _context.PostAuthenticateRequest
Const networkAuthenticationRequiredStatusCode As Integer = 511
Try
If IsVideoUrl() Then
If _context.User Is Nothing Then
LogManager.WriteMessage("_context.User is nothing:", "")
End If
Dim userId As Integer = myUserManager.GetUserIdByUserName(_context.User.Identity.Name)
If (UserRequiresAuthorization(userId)) Then
If Not UserIsAssignedToCourseContainingVideo(userId) Then
LogAccessDeniedMessage()
_context.Response.StatusCode = networkAuthenticationRequiredStatusCode
_context.Response.ClearContent()
_context.Response.Write("UnAuthorized User")
_context.Response.End()
End If
End If
End If
Catch ex As Exception
LogManager.WriteException(ex, "")
End Try
End Sub
End Class
To ensure that _context.User is set add the runAllManagedModulesForAllRequests="true" to the modules section of the web.config like below.

I have the following problem:
The call from a WebMethod is not being done on a project created in Visual Studio 2013 (ASP.NET WebForms Application). If I create a project, for example, in Visual Studio 2008 and migrate to VS 2013 works correctly. The problem only occurs when I create a new project in Visual Studio 2013. There is no error message in the console. The WebMethod is just not being called. Nothing happens. I searched a lot but found nothing about it.

Has anyone tried this or know of a solution? I have no idea what to do ...
EDIT:
Guys, I discovered one more information now:
Working only in VS2013:
-New project.
-Web - ASP.NET Web Application.
-Select the template "Empty".
-Insert a page "Default.aspx", the WebMethod works normally ...
Now, if you create a new project and select the template "WebForms", does not work ...
Can be cross-referenced? or some different setting?
I found the solution to my problem: What prevented the WebMethod was called was the reference to "System.Web.Optimization". Not sure how he does it, but as I will not use it at the time, decided to remove:
"System.Web.Optimization" and "Microsoft.AspNet.Web.Optimization.WebForms"
It is also necessary to remove the web.config as follows:
<namespaces>
<add namespace="System.Web.Optimization" />
</namespaces>
<add assembly="Microsoft.AspNet.Web.Optimization.WebForms"
namespace="Microsoft.AspNet.Web.Optimization.WebForms" tagPrefix="webopt" />

<bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234" />

All ok now! Thanks to everyone who helped me with the problem! :)
Add this section in web.config after httpModules.

You have to bind btnSend_Click handler to the button:
<asp:Button ID="btnSend" runat="server" Text="Send Mail" OnClick="btnSend_Click" />
Having trouble figuring out how to impersonate another user while using aspnet_personalization with Windows authentication.
I am using asp.net's personalization framework on my page:
<asp:WebPartManager ID="WebPartManager1" runat="server" >
<Personalization Enabled="True" />
</asp:WebPartManager>
My page is in an existing web app that uses AuthenticationMode="Windows" (which I cannot change, and IIS is also set to Windows Authentication). This web app has a page that allows super-users to impersonate any other user. This is accomplished by manipulating a connection string that is built dynamically every time we hit the database.
My problem is that aspnet_personalization still uses windows authentication. When I try to edit the connection string used by aspnet_personalization dynamically, aspnet does not seem to use it - it still uses the username of the current NT account.
I have the following in my web.config's configuration tag:
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="AnotherConnectionString" connectionString="Data Source=serverName;Initial Catalog=dbName;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<membership>
<providers>
<remove name="AspNetSqlMembershipProvider"/>
<add name="AspNetSqlMembershipProvider"
type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a"
applicationName="/"
connectionStringName="AnotherConnectionString" />
</providers>
</membership>
<profile enabled="true" defaultProvider="TableProfileProvider">
<providers>
<clear />
<add name="TableProfileProvider" type="Microsoft.Samples.SqlTableProfileProvider" connectionStringName="AnotherConnectionString" table="aspnet_Profile" applicationName="/" />
</providers>
<!--<properties></properties>-->
</profile>
I tried editing the connection string by adding code as follows whenever we impersonate a user, hoping asp.net would use it, but it does not:
Dim settings = ConfigurationManager.ConnectionStrings("AnotherConnectionString")
Dim fi = GetType(ConfigurationElement).GetField("_bReadOnly", BindingFlags.Instance Or BindingFlags.NonPublic)
fi.SetValue(settings, False)
settings.ConnectionString = "data source=serverName;database=dbName;user id=" & login & "; password=" & password
I did confirm on page_load of the page containing the webPartManager that "AnotherConnectionString" does contain the desired username, but asp.net_personalization still calls its stored procs using the NT username.
ANSWER:
Stackoverflow won't let me post an answer. That's ridiculous, so after I post the answer inside the question, I'm deleting my account and will encourage others to do the same.
I solved the problem by extending SqlPersonalizationProvider:
Imports System.Web.UI.WebControls.WebParts
Public Class MySqlPersonalizationProvider
Inherits SqlPersonalizationProvider
Protected Overrides Sub LoadPersonalizationBlobs(ByVal webPartManager As System.Web.UI.WebControls.WebParts.WebPartManager, ByVal path As String, ByVal userName As String, ByRef sharedDataBlob() As Byte, ByRef userDataBlob() As Byte)
Dim impersonatedName As String = MySession.UserLoginName()
path = path & "|" & impersonatedName
userName = impersonatedName
MyBase.LoadPersonalizationBlobs(webPartManager, path, userName, sharedDataBlob, userDataBlob)
End Sub
Protected Overrides Sub SavePersonalizationBlob(ByVal webPartManager As System.Web.UI.WebControls.WebParts.WebPartManager, ByVal path As String, ByVal userName As String, ByVal dataBlob() As Byte)
Dim impersonatedName As String = MySession.UserLoginName()
path = path & "|" & impersonatedName
userName = impersonatedName
MyBase.SavePersonalizationBlob(webPartManager, path, userName, dataBlob)
End Sub
End Class
And then in web.config:
<system.web>

<remove name="LocalSqlServer"/>
<add name="MyConnectionString" connectionString="Data Source=MyServerName;Initial Catalog=MyDatabaseName;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
and on the page:
<asp:WebPartManager ID="WebPartManager1" runat="server" >
<Personalization Enabled="True" />
</asp:WebPartManager>
Looks like I'm allowed to post an answer now. I guess I won't delete my account after all. But geez, SO isn't very friendly to noobs.

path = path & "|" & impersonatedName
userName = impersonatedName

End Sub
Protected Overrides Sub SavePersonalizationBlob(ByVal webPartManager As System.Web.UI.WebControls.WebParts.WebPartManager, ByVal path As String, ByVal userName As String, ByVal dataBlob() As Byte)
Dim impersonatedName As String = MySession.UserLoginName()
path = path & "|" & impersonatedName
userName = impersonatedName
MyBase.SavePersonalizationBlob(webPartManager, path, userName, dataBlob)
End Sub
End Class
And then in web.config:

and they are each within their own folders.
Please help.
Get rid of the namespace attribute, as it's confusing ASP.NET as to whether you're attempting to register a User Control or a Custom Control.
User Control:
<add tagPrefix="SomeTagPrefix" src="~/Controls/SomeControl.ascx" tagName="SomeTagName"/>
Custom Control:
<add tagPrefix="SomeTagPrefix" namespace="SomeNamespace" assembly="SomeAssembly"/>
So, in your example:
<add tagPrefix="IPAMControl" tagName="track" src="~/controls/track.ascx" />
And on the ASPX/ASCX, you use it like this:
<IPAMControl:track id="ipamTrack" runat="server" />
See here for more info.
EDIT
To prove this works - i did the following:
Create new Web Application
Create new folder called "Controls" in the root of the web application
Added a new "Web User Control" called "MyUserControl.ascx"
Modified web.config to add registration of control
Modified Default.aspx to add the control.
And it all works fine.
Here is the User Control:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="MyUserControl.ascx.cs" Inherits="WebApplication1.Controls.MyUserControl" %>
<span>Hi, im a user control, how are you?</span>
Here is the portion of the web.config i edited:
<pages>
<controls>
<add tagPrefix="MyControls" tagName="MyUserControl" src="~/Controls/MyUserControl.ascx"/>
</controls>
</pages>
Here is the Default.aspx change i made:
<MyControls:MyUserControl id="myUserControl" runat="server" />
And the page rendered correctly.
Now, unless what i have done here is different to how you have attempting to do it, you must have other code/errors that is interfering with this.
Don't know how much else help i can be.
