Connecting web parts: The easy way

October 9, 2008   17:38

Exactly one year ago (and wow I did not time this!) I posted a blog about “Connecting a web part with a standard SharePoint list”. For my current project I had to develop 2 web parts that could connect with each other.

Since Moss2007 you can implement your own connection interface which enables you to connect customized web parts. It looks like you can basically transfer any serializable information.

The first thing you have to do is to define a very simple interface. The second step is to inherit the interface at the web part class that sends the information. In this class you’ll have to assign the interface as the connection interface. The last step in the provider web part is to include the “get function” described by the interface to pass the value.

In our consumer web part we have to retrieve the connection interface. Once this connection has been setup we can read and use the given value.

In the example code we will use the interface with the name “IMossStringConnection” to pass a string value.

This product requires ASP.NET v2.0 to be set to ‘Allow’ in the list of Internet Information Services (IIS) Web Server Extensions

I’m currently performing a migration process and during the Moss installation the following error message is presented:

“This product requires ASP.NET v2.0 to be set to ‘Allow’ in the list of Internet Information Services (IIS) Web Server Extensions. If it is not available in the list, re-install ASP.NET v2.0.”

But on my machine Visual Studio 2005 and .NET2 are installed, so that’s a bit strange. Checking out the IIS extensions panel is indeed not showing the v2.0 version.

To solve the issue open your command prompt en navigate to:
%drive%\Windows\Microsoft.NET\Framework\v2.0.nnnnn
where nnnnn is the least significant version number of ASP.NET 2.0.

Now run the following command at the command prompt:
“aspnet_regiis.exe -iru -enable”
and the issue should be fixed.
