SharePoint 2003 & SQL Server 2005

The answer is Yes...as long as you're using Service Pack 2. Note that the installation process is a bit different. Instead of going through the complete installs (ie, creating the config & content databases) you stop midstream, install SP2, then carry on.

Where are my Custom Properties?

So you've been doing web part development on SPS2003, you've built web parts with custom properties, which are found when you switch to edit page, edit web part properties. All well and good. Now along comes WSS v3 which use ASP.Net 2.0 web parts as well as SharePoint web parts.

You install the VS.Net 2005 extensions for WSS, you build the sample web part project as described in MSDN, you see that indeed custom properties are supported, cool.

So now you go and copy over some code from your SPS 2003 web parts, you've got the code to add in your custom property:

[Browsable(true), Category("Miscellaneous"), DefaultValue(defaultText), WebPartStorage(Storage.Personal), FriendlyName("Text"), Description("Text Property")]
public string Text
{
get { return text; }
set { text = value; }
}

But when you go to edit your web part properties - this custom property isn't there!!

Here's the catch. From the example in the SDK, the custom property isn't really visible to the ASP.Net web part - instead, the HTMLTextbox control is added to the web part, with an HTMLButton used to call the SaveProperties method.

All well and good, but to me this means my end users can see all of those ugly properties! If the properties are only visible on the Web Part Properties page, using the new security trimming the end user wouldn't be able to see the properties. I'm not so concerned about securing the values of the properties, I just don't want to clutter up my web pages with all these text boxes!

I suppose I could add in code to check the user's security and use CSS to hide the properties, but then that's a performance hit.

The answer: go back to good ol Microsoft.SharePoint.WebPartPages.WebPart instead of System.Web.UI.WebControls.WebParts.WebPart. That is - instead of using the ASP.Net web part base class, you'll need to use the SharePoint web part base class. You can see this yourself if you switch the base class of that SDK sample - now, a Miscellaneous section will appear on the web part properties because the web part is a SharePoint web part, not an ASP.Net web part.

You might also get an error if you try to add a web part that was originally an ASP.Net web part that you re-based the class to become a SharePoint web part...looks like the answer, unfortunately, is to create a brand new project using these instructions:

Creating a SharePoint Web Part


I've only tried this on WSS, but that's sure what seems to be going on...

So you're ready to deploy your webpart....

You've built your web part, deployed it on your VPC, now it's time to deploy it on the production WSS box...here's what I did.

  1. In Visual Studio, switch to Build configuration
  2. Rebuild and deploy once again to your local VPC
  3. Go to the project\bin\release directory, look for Setup.bat, and edit the file, looking in line 22 to change the target URL from your http://myserver VPC server to http://prodserver
  4. Zip up the entire Release directory, then copy it to your prod server
  5. RDC to the prod server - you'll need to use an account that's in the SharePoint admin group. Otherwise when you run the stsadm.exe command you'll get some Object Not Found error messages, or messages about being unable to bind to SQL Server
  6. Unzip your project, then run Setup.exe
  7. Once done, the web part will be activated on the root site of your portal/WSS site. You can open it up, then add in the web part. You could also go to any other site and activate the web part and do the same.
  8. When you add in your web part, if you get the error message: "Unable to add selected web part(s). Incompatible Web Part markup detected. Use *.dwp Web Part XML instead of *.webpart Web Part XML", well, the catch is you're using the wrong project base class. That is - with WSS/MOSS, you can use the ASP.Net 2.0 web part framework, or the good ol SharePoint web part framework. The SDK provides a good explanation of this. If you built your web part from the VS.Net template, then you'll need to make sure you're using the ASP.Net base class: System.Web.UI.WebControls.WebParts.WebPart instead of Microsoft.SharePoint.WebPartPages.WebParts. How to fix this? That's for another post.

Must have's for VS2005 SharePoint coding

You gotta have the following:

Code snippets - you can add snippets to create the code structure for your entire web part or a web part property:

Windows Workflow Foundation. Doing workflow development? You'll need this installed first, otherwise you'll get a goofy error message when you try to instantiate the workflow (forgot to copy it):

Details about Site Enumeration

There are a few different ways to enumerate sites through the SharePoint Object Model. One thing to keep in mind: a 'site' in OM lingo refers to a top level site. Everything else - subsites - are referred to as 'webs'.

When you create a new SharePoint site, unless you're creating a new Site Collection through SharePoint Central Administrator, you're creating a subsite on an existing site collection. This is true from the root WSS site - http://myserver - any sites created through the Site Actions menu are subsites of the root site.

So - here are some properties I use to crawl through the set of site collections & subsites.

SPSite.AllWebs - this property of the SPSite object returns the top level site as well as all of the subsites of the top level site. This is helpful if you need to get a list of all of a WSS web application's sites and subsites, say if you were doing a site specific backup or report. But since the data listed isn't hierarchical, if you want to build a site tree view not all that helpful.

SPSite.RootWeb - this returns the SPWeb object for a site. Most useful when you get a top level site and want to look at the contents of the site, not just site properties.

SPSite.RootWeb.Webs - this returns just the site collections underneath the SPSite object.

SPWeb.Webs - returns the sites immediately underneath the SPWeb site

Now, let's say you want to open up the URL http://server/sites/sc1/subsite1 using the following line of code:

SPSite parentSite = new SPSite("http://myserver/sites/SC1/SubSite1")

If you look at parentSite.Url, you'll see the URL to the site collection: http://myserver/sites/SC1, and not the Subsite you wanted. There's probably a more elegant way to do this, but what I do is use the AllWebs property then get the site relative URL ('SubSite1') as the AllWebs indexer:

String targetUrl = "http://server/sites/sc1/subsite1";
String relativeUrl = targetUrl.Replace(parentSite.Url, ""); // parentSiteUrl = http://myserver/sites/sc1
SPWeb subsiteWeb = parentSite.AllWebs[relativeUrl]; // relativeURL = 'SubSite1'

SharePoint web parts vs ASP.Net 2.0 web parts

When I was setting up my second WSS v3 web part (got HelloWorld to work!) I needed to add in a web part property. I copied in the correct code, but that property just would not appear when I edited the web part settings. The culprit: When developing a web part for WSS v3 or MOSS, make sure to extend Microsoft.SharePoint.WebPartPages.WebPart instead of System.Web.UI.WebControls.WebParts.WebPart. That is:

public class MyWebPart: Microsoft.SharePoint.WebPartPages.WebPart

instead of

public class MyWebPart: System.Web.UI.WebControls.WebParts.WebPart

You might also want to remove the reference to System.Web.UI.WebControls.WebParts from your Using/Imports statements.
