When I create a new sharepoint template for my project use, I want to set the value for webpart’s properties as soon as the site created using this template. Adding a list by default is easy after my reading of the great article from http://aspalliance.com/ . I have developed a webpart for list displaying, and I know how to add this webpart in the rootweb by default, but I don’t know how to set value for the webpart’s properties by default. When I open a Onet.xml from one built-in template I got a example as follows:
1 <AllUsersWebPart WebPartZoneID="Right" WebPartOrder="1">
2 <![CDATA[
3 <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2" xmlns:iwp="http://schemas.microsoft.com/WebPart/v2/Image">
4 <Assembly>Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>
5 <TypeName>Microsoft.SharePoint.WebPartPages.ImageWebPart</TypeName>
6 <FrameType>None</FrameType>
7 <Title>网站图像</Title>
8 <iwp:ImageLink>/_layouts/images/homepage.gif</iwp:ImageLink>
9 </WebPart>
10 ]]>
11 </AllUsersWebPart>
I believe line 8 is the key of my problem. And now the problem is how to set the iwp prefix. After my reflector of Microsoft.SharePoint.WebPartPages.ImageWebPart, I got some interesting code fragment below:
1 [Guid("20743A06-C4E6-4984-A8A0-918C34353148"), XmlRoot(Namespace="http://schemas.microsoft.com/WebPart/v2/Image")]
2 public sealed class ImageWebPart : WebPart, IDesignTimeHtmlProvider, ICellConsumer
3 {
4 //
5 }
Compare xmlns:iwp="http://schemas.microsoft.com/WebPart/v2/Image" to XmlRoot(Namespace="http://schemas.microsoft.com/WebPart/v2/Image"), I know the answer. my webpart xmlroot is "Microsoft.MCS.HPITeam.Portal.WebParts", so I registered my webpart as following:
