i have installed ajaxtoolkit 3.5 but when i debug i am getting this error Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' even i have changed my tags to

So, I've been programming for a number of years. Finding some intricately asinine issues w/ ASP.NET and VB.NET as I learn them. How about this one:
[Code]....
The issue is not Date1
The issue is Date2.
No kidding. I had to String.Format Date1 for some odd reason, even though I'd already validated it. And, yes, I tried to parse and convert Date1 but I kept gettting the typical "Argument 'Date2' cannot be converted to type 'Date'." error. (Did you catch the copy & paste? I didn't edit it from my existing error, but Date2 should be Date1.) Yeah, that's the error I'm getting now with the above ...
"Argument 'Date2' cannot be converted to type 'Date'."
Date2 is a system defined type. Why can't the system convert and/or simply use it's own pre-defined type?

I have a strange problem. I am adding a LinqDatasource object, and set the context:
[Code]....
Then I get this error:The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
On web.config I already have this:
<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.
is there another way adding a refernce to a web project? or only though teh web.config?

[Code]....
First of all, let me explain the situation, I know this is a bit complicated.
And I apologize for my poor English.I have created a dll library which contains the classes I created.I tested the library with Console Application and web site created with Visual Studio 2005,everything works fine.So I copied the dll to the "Bin" folder of a running ASP.NET 2.0 web site, added reference to the dll file, imported the namespace, then trying to initiate instances of objects in the dll.
I created a small new webservice for AutoCompleteExtender and for some reason I am getting "type System.Web.Script.Services.ScriptService is not defined" error. I Googled this and found a few threads about similar issues but was unable to resolve mine. Here is the example of the code:
[Code]....
When I add Imports System.Web.Script.Services I get "Namespace or type specified in the Imports 'System.Web.Script.Services' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases".
I've tried adding Reference to System.Web.Extensions and it didn't do anything. What could be the problem?
I've set up a strongly-typed View and a controller method to save the object represented in that View. The object in question is from a class that uses named parameters with default values. This is not a database object, but rather is the intermediate object that is used for the display and user input. It gets translated into a database object in the service class. Anyway, when I attempt to save the object, I get the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
This is kind of aggravating. I can add a parameterless constructor to the class, and then everything works just fine. I just don't understand why it is necessary. I'm new to named parameters with default values, but the reading and such that I've done has described that method calls with default values do not have to have a 'no-parameter' implementation. You can just call the method with any or none of the parameters specified and everything works as expected. If there is a 'no-parameter' implementation and no params are passed, then that one is used, since it is more specific than the one with default values. Is the behavior somehow different when this is used in the constructor of a class? Why would I have to include a parameterless constructor when I have all the values accounted for? Is the runtime creating an object on the fly as the save method executes, which requires this? The method is like this:
[Code]....
I'm wondering if the object is instantiated by the runtime in order to populate the method parameter, and then assigned values from the form collection. I suppose that would make sense, but I do not understand why this causes an exception. For what reason would a parameterless constructor be required?

I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.

The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.

I'm getting the error from the subject line when I try to move some code that formerly lived in the App_Code directory to an external library (that would be moved into the /bin directory). What do I need to include or reference to get rid of this error?
I've already included: System.Runtim.Serialization (says it's version 3.0.0, I don't see a version 3.5.0 anywhere).
I am getting an error in a web application "The base class includes the field 'ScriptManager1', but its type (System.Web.UI.ScriptManager) is not compatible with the type of control (System.Web.UI.ScriptManager)." .The application has been converted from VS2003 to VS2005. How this error can be corrected?
View 1 RepliesI put a server side button on the header page. The website is running fine. I use the same source and put it on IIS, it's also working fine but the problem is, i couldn't compile it anymore using my VS studio. It's showing no error so when I go and check the output (after scrolling down a bit and found one line says error). it says

keyword is the textbox on the header page. I also played around with AutoEventWireUp (true/false) and defining onclick event on the server tag but it is still not solving the problem.
