Custom Server Controls :: TypeConverter Generates Parser Error At Runtime?

Jun 20, 2010

I'm building a custom control that has a ValidationText property of type List<string>. The value of the property is rendered as a comma-delimited string in the XHTML code. Changing the value in the String Collection editor updates the XHTML code and vice versa. So everything seems to work at design time. But... when I run the project I get a parser error:

"Cannot create an object of type 'System.Collections.Generic.List`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' from its string representation 'hh,ss' for the 'ValidationText' property."

Here is the code for the property:

...and the Typeconverter:

DataSource Controls :: Generates Unspecified Error On Opening File On Production Server

Jan 5, 2010

I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).

string connectionString = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";") + "Extended Properties="Excel 8.0""
OleDbConnection connection = null;
connection = new OleDbConnection(connectionString);
connection.Open();

The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.

Intermittent XML Parser Error "XML Parser Error:no Element Found" From Time To Time?

Apr 27, 2010

I have deployed my website to a shared hosting provider and since deployment, it shows the error "XML Parser Error:no element found" from time to time. I have checked my error log and I find issues such as "Object reference not set to an instance of the object" but the weird thing is if I visit the SAME page after a while, it loads!

I have checked with my hosting provider and they told me the below is what they can see on their side:

Exception information:
Exception type: HttpException
Exception message: Could not load type 'Test2.GlobalAsax'.

I have checked my global.asax and the interits are all correct. I have tried:

a) Deleting the webapplication dlls and rebuilding - didn't work

b) Deleting the global.asax and adding a new one and then rebuild. - didn't work

c) Changing the class name of global.asax.vb and updating at inherits at global.asax, and rebuild - didn't work

d) Change the Asp.Net version to an older version and change back to original version - didn't work

e) Debugged my application countless times locally (for the same page) but while connecting to the DB on my hosting provider - no issues found

My webhosting provider is saying there is an error in my code, but if there is a bug, shouldn't it always show the same error?

I also noticed that when the XML parser error is shown, if I were to go back to say Google.com and then to my website's main page, and then to the Page with error, the page loads!!

I am seriously running out of ideas what could have caused this issue. I have also conducted a ping test to my website and I am getting some time outs, will that cause my page to not load from time to time?

Custom Server Controls :: Custom Control Design View Error

Aug 13, 2010

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'

This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.

Property Code Example:

[Code]....

I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it does.

Error On One Server But Not Another (Server Error In '/' Application Runtime Error)

Feb 5, 2010

On one server I have my ASP.NET 3.5 website running just fine. That server is the one we use for testing (IIS6 with ASP.NET 2.0.50727). I went to the live server where ASP.NET is also installed (IIS6 with ASP.NET 2.0.50727). I right-clicked on the folder I wanted my website to go in, and I set it as an application in IIS. But when I go to the website on the live server, I get the Runtime Error. Like the error told me to do, customErrors mode is "Off" in the web.config file. I even changed authentication mode to "None" (it was set to Windows on the test server). Yet I still get this error. Is there something I should change about the web.config file? Is there something I should check in IIS?

For reference, here is the full error message. Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

Custom Server Controls :: Error - Embedded Resources Not Found

C# - EDMX New Column Generates Error On ToList() Call

Jan 27, 2011

We've added a new column to a database table. The column is defined as follows:

Name: DisplayAsSoldOut
Type: Boolean
NOT NULLABLE
Default Value: 0

We've refreshed our EDMX data model and the new column appears just fine. We are on an ASP.NET 4.0 platform using C#.

We have a class defined as PagedList which inherits from List and implenents an interface IPagedList

Within the PagedList we have the following method:

[Code]....

When we reach the following line:

{ AddRange(source.Skip((index) * pageSize).Take(pageSize).ToList()); }

we receive the following Exception ...

Type: System.Data.EntityCommandExecutionException
Inner Exception: "Invalid column name 'DisplayAsSoldOut'."

I've tried searching for this type of exception but to no avail. The column appears in the EDMX dataset just fine. I even created a small throwaway program and imported the EDMX to do a simple read from the database and it worked fine. Has anyone run across something similar?

Custom Server Controls :: Page Cannot Be Null Error, Or Blank Databound Controls

Feb 24, 2011

So I finally managed to create a control which basically shows a bunch of Panels with an extra property. I use it like this:

[Code]....

This renders fine and shows the text in the TabPanel controls. However, when I replace the plain text with something a little more exciting, say an UpdatePanel so it looks like this:

[Code]....

Then I get this weird error:

If I take out the UpdatePanel and replace it with an ASCX control I made that simply puts database data into some DropDownLists, like this...

[Code]....

Then the page loads, but the data is not loaded into CustomerUserList1, and the dropdownlists within it are all blank. CustomerUserList1 has worked fine for years when used directly in a normal Panel/Page UpdatePanel.

Custom Server Controls :: Registering Controls Of Current Assembly Object Reference Not Set Error

Aug 21, 2010

I have created a simple ASP.net Web Application (2.0) and have added a web user control.

Now in my page I have added this control but I have registered like this,

<%@ Register Assembly="WebApplication1" Namespace="WebApplication1" TagPrefix="Custom" %>

Which means I want to access all the controls in my current Web Application project

Then I have added my user control like this,

<Custom:MyUserControl ID="MyUserControl1" runat="server" PublicProperty="Hello" />

Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"

Note that My Control has,

1) Public property PublicProperty as String

2) 1 Label control

In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).I don't want to register my control using Src, TagPrefix etc.
