MOSS Questions And Answers

21⟩ Explain Application Pages in SharePoint?

One can create custom application pages to add GUI components in Sharepoint. Unlike site pages, an application page is deployed only once per Webserver. Application pages cannot be customized based on sites, and are based on virtual _layouts directory. Application pages are all compiled together into a single dll and are also used across all sites within a server farm. They are preferred to site pages because of their performance benefits over them and they also support inline code.

27⟩ Which one is Better a UserControl or a WebPart?

Comparison of UserControl and WebPart

Advantages of UserControl:

Developers are already familiar with user controls which reduce the learning curve.

UserControls can be used with other ASP.NET applications. Hence reusable.

Developing user controls using Visual studio is much faster than building it through code as in the case of WebParts.

Disadvantages of UserControl:

There is a performance overhead as usercontrol use a shim as a wrapper to work with Sharepoint.

Deployment is a bit messy.

Advantages of WebPart:

Everything is available and customizable, i.e. toolbar, behavior, content etc.

Better performance as there is no shim wrapper.

Provide a structured deployment mechanism.

Disadvantages of WebPart:

Developers are unfamiliar so learning curve is steeper.

They are strictly for Sharepoint and won’t work with other ASP.NET applications. Thus not reusable.

32⟩ How to return SharePoint List items using SharePoint web services?

Create a reference to the SharePoint Lists.asmx web service by appending “/_vti_bin/Lists.asmx” to the end of a site name. One can use this url to add a service reference in Visual studio there onwards. This will query the WSDL for the Lists.asmx service.

Next step is to configure the security to be able to call the service methods. You can do this by altering the bindingConfiguration to indicate the transport uses NTLM authentication, which is the default.

We can then iterate through all the lists.

e.g:

ServiceReference1.ListsSoapClient proxy = new ServiceReference1.ListsSoapClient();

proxy.ClientCredentials.Windows.ClientCredential = new NetworkCredential();

XmlNode node = proxy.GetListCollection();

XPathNavigator nav = node.CreateNavigator();

XPathNodeIterator iter = nav.SelectDescendants("List", "http://schemas.microsoft.com/sharepoint/soap/", false);

while (iter.MoveNext())

{

string title = iter.Current.GetAttribute("Title", string.Empty);

string id = iter.Current.GetAttribute("ID", string.Empty);

Messagebox.Show ("title:" + title + “ and id:” + id);

}

writer.Flush();

38⟩ Explain page layouts of MOSS?

Page layout defines the look and feel of a Web page. Content for the page is stored in fields on the page. When you view or edit a page, the content is displayed in the field controls.

The types of fields on a page are determined by the content type for the page. Each content type contains columns. When you create a content type, you add column templates to the content type for each field. Column templates determine the default field control that is associated with the columns as well as the kind of content the field can contain, such as a single line of text, a hyperlink, or a picture.

Types of page layout columns:

Scheduling Start Date: displays the date and time when the page is visible on a site.

Scheduling End Date: It contains the date and time in which the page is no longer visible on a site.

Contact: contains the name of the person or group who created the page.

Contact E-mail Address: Page Content: contains the name of the page layout associated with each instance of a page. contains the e-mail address of the person who created the page.

Contact Name: contains the name of the person who created the page.

Contact Picture: contains the picture of the person you can contact about the page.

Page Content: contains the name of the page layout associated with each instance of a page.
