Hi All

After downloading and installing the EO.Web controls I added a DatePicker to one of my ASP.NET pages, using VS 2005. After doing that I get the following error:

“Element 'DatePicker' is not a known element. This can occur if there is a compilation error in the Web site.”

I also tried other contorls as a test i.e. The Calendar control, but recieved the same error.

Does anyone know the reason I would be receiving this error message?

I’ve double checked the following:
1. The EO.Web.dll file is in the bin folder of my application.
2. The EO.Web controls install added the EO.Web reference and list of OE.Web tools to my VS Enviroment.
3. The following header is at the top of the ASP.Net page I’m adding the DatePicker control to:
<%@ Register Assembly="EO.Web" Namespace="EO.Web" TagPrefix="eo" %>

I did notice though that even though the demo url (http://localhost:1446/EOWebDemo/Default.aspx) opens with no problems the Live Demos that were added during the install don’t work correctly.

Any help on this would be really appreciated.

Thanks
Code: C#

		    Hi,

Make sure your project is a local project. Otherwise Visual Studio may not be able to load EO.Web.dll due to permission issue. In that case you can try to add EO.Web.dll into your GAC. Once added into GAC, you can then reference the control from GAC and that should solve the permission problem for you.

I do not know why the Live Demos does not work. Can you provide more information such as detailed error message? You can also load the sample project directly with Visual Studio by going to Start -> All Programs -> EO.Web Controls 7.0 (2009) -> EO.Web for ASP.NET 2.0 & Above -> Live Demo -> Live Demo Source Code.

Thanks!

		    Hi there, 

Thank you for the fast reply.

The project is on one of our servers, which I'm unable to change. I'm developing the application from my mahcine however which is in the same domain as the server. Would this be causing the problem? If so is there anyway around it? Sorry what is GAC and how would I add the ddl file to it?

Please let me know where I can find a more detailed error message to provide you with and i'll post it right away, thanks.

Thanks for your help with this.

Mel

That explains why. GAC is global assembly cache. If you are interested in knowning what it is, you can search online and you should be able to find plenty of information about it. 

Here is a more information on how to add our DLL to GAC:

http://doc.essentialobjects.com/library/1/installationanddeployment/gac.aspx

Note you may need to download .NET 2.0 SDK in order to have "Microsoft .NET Framework 2.0 Configuration" in your "Administrative Tools".

Once you add your control to GAC, you would delete the existing EO.Web entry from your project -> References, then add it again, but this time choose the DLL from the ".NET". After that your project will try to load the DLL from GAC instead of from your bin folder.

Steps for adding a DLL to GAC or referencing a DLL from GAC are the same for everyone. It's a .NET thing so there is nothing particular as to our product. Thus you can find any article online on this topic (there should be plenty) and follow it if you are still not clear about how to do it.

You mentioned "Live Demos that were added during the install don’t work correctly". We do not know how it does not work for you. So you will need to tell us that first. 

Thanks!

		    Thank you for the information after adding the DLL file to the GAC and carrying out some additional steps i was able to include the DatePicker control with no errors.

Thanks again.

		    I was under the impression that the DatePicker control was one of your free controls. I guess not. A great app and very good/timly support doesn't come for free I guess. It's a shame I won't be able to use it.

		    Sorry about the confusion. Unfortunately no, as you have correctly concluded, great app and support does not come for free. We would not be able to afford it even if we would like to. Sorry about that!
