The xml provider is for creating pages structured in an xml file. (Given in the filePath attribute above) If you are trying to connect to a database, just configure your EPiServerDB connectionstring in the file connectionstrings.config

Set up the Data Source to your db server name and your initial catalog to match your database name.

If you are actually trying to store your data in an xml file with the xml page provider, you can read more about the provider here:

Hey,

Thanks for the reply.I am storing my data in an xml file with the xml Page provider.I am following the same thing but my page is not displaying the xml content . In which location I have to add provider code in my web.config.I have placed it in between the </episerver.baseLibrary> tag. 

</classFactories><pageProvider><providers>add name="XmlPageProvider" type="CodeSamples.XmlPageProvider, XmlPageProvider" entryPoint="75" capabilities="Create,Edit,Delete,Move,Copy" filePath="~\externalpages.xml"/></providers></pageProvider></episerver.baseLibrary>

and page provider node in the site's page tree is a page of start type.

You should not have it inside the episerver.baselibrary tag. Take it out of web.config and put it inside the <episerver> tag in your episerver.config file.

Hey,

Thanks for the reply.I just have put the code inside the episerver.config, but its giving reeor message:

Cannot create an instance of type CodeSamples.XmlPageProvider, XmlPageProvider

The type attribute requires a full namespace. Check what namespace you have and replace "CodeSamples.XmlPageProvider, XmlPageProvider" with your namespace

Hey, Following error is thrown away when I try to run my XMLPageProvider.

Are you still using the configuration from your first post? If so, have you downloaded the externalPages.xml file and placed it in your site's root folder? 

The code crashes on a line where it is trying to retrieve the physical path of the xml file.

Hey,

thanks for the reply

I got following error in my page.

!EPiServer.Core.InvalidPropertyValueException was unhandled by user code
  Message="\"05/20/2010 09:04:00\" is not a valid value for \"EPiServer.Core.PropertyDate\"."
  Source="EPiServer"
  InnerException: System.FormatException

Answer before you changed your previous post:

I'm confused, is HttpContext.Current null???

Try this:
- set a breakpoint at line 55 in XmlPageProvider.cs
- go to the Immediate Window, type configParams["filePath"] and press enter. What do you get?
- same, but type HttpContext.Current.ToString()  What do you get?
- if the previous doesn't fail, do you get anything when you type (copy/paste) HttpContext.Current.Server.MapPath("externalpages.xml") ?

Hi,

Thanks for the reply.......!

1) I have added breakPoint in line 55 in XmlPageProvider.

2) configParams["filePath"] is showing "~/externalPages.xml"

3) HttpContext.Current.ToString() displays : object.ToString is a Method which is not valid in given context.

4) After typing HTTPContext.Current.Server.MapPath("externalPages.xml") result is Http Context.Xurrent is null.

I tries this previously  and didnt got any solution so I changes my this line No 55 to following one ie:

_filePath = AppDomain.CurrentDomain.BaseDirectory + @"/externalPages.xml";

and now I am getting filePath.

Ok. Regarding the InvalidPropertyValueException you get now, this might be related to localization. The date format in the XML file is mm/dd/yyyy hh:mm:ss  Not sure about dateformats in India, but try to change the dates in the XML to match your date format.

Hi,

Hey..........Yeh! My page is now displaying the xml content .

Thank you so much for the replies.:)

Now the only thing I want to know is that  in XMLPageProvider I got XmlPageProvider.CS and complete solution that I just added as a reference in my project. Is the customPageproviders is also same .How do I get the databaseProvider.CS,Or I have to create it on my own.

Thanks

Bharti

Do you mean a custom database provider? When you install EPiServer, the default storage option is database. 

Hey,

Yes my mean is Custom DatabaseProvider.like in the following link:

http://world.episerver.com/Templates/Forum/Pages/Thread.aspx?id=43613&epslanguage=en&pageIndex=2

but the NorthwindProductProvider.CS and the Northwind.dbml.Is this a class or what .

The link is to this page :-)
