Listing 13-5.

To describe your classes and members therein, you can use two tags: <summary> and <remarks>. The <summary> tag is used to describe a type or its members. The <remarks> tag is used to specify additional information about the type or member other than that specified in <summary>. Listing 11-33 shows the SimpleCalculator class after adding <summary> and <remarks> tags. Listing 11-33. Adding <summary> and <remarks> /// <summary> /// This is a class that represents /// a simple mathematical calculator. /// </summary> /// <remarks> /// This class is developed on .NET 2.0 /// </remarks> public class SimpleCalculator { ...

Expose the Observables for both the KeyUp event of the zip code text box and for the web service callback by adding the following two methods to your code:

Under the Global Settings heading are two fields, Primary Links and Secondary Links, which you can use to create a set of links that can then be displayed on your site. While this isn t the only way to create navigation links, it is a practical and quick way to get the job done. Primary and secondary links can be set only at the global level, not for individual themes. A primary or secondary link consists of three pieces of information that you enter in the three columns of the table provided: Link Text, URL, and Description. The link text is the part of the link that is visible. The URL can be either an absolute URL (beginning with http://) or a Drupal path. Absolute URLs are used to link to other sites or resources on your server outside Drupal, whereas any resource inside Drupal (such as your blogs, forums, pages, or recent posts) are represented by a Drupal path. The description will be used for the title parameter of the resulting <a> tag, or hyperlink, which will be created. Here are some examples of primary and secondary links:

cmdReport.CommandText = "SELECT * FROM TransferHeader ORDER BY TransferID; SELECT * FROM TransferDetail ORDER BY TransferID"; Next, I load the data from the data reader to the data set by calling the load method like this: dsReport.Load(drReport, LoadOption.OverwriteChanges, dsReport.Tables[1], dsReport.Tables[0]); If you notice, I m calling the load method and passing some extra parameters to first set the overwrite condition and then pass each table a reference from the dataset to fill. You might be wondering how the subreport manages to get the data. For that I have to create a handle, which looks like the following: reportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(SubreportProcessingEventHandler); I add this event handler to the SubReportProcessing event of the main report. Then I add another method SubreportProcessingEventHandler, which responds to this event. The code behind my method takes care of getting the data for my subreport. The code inside my method looks like this: e.DataSources.Add(new ReportDataSource("dsTransfer_dtTransferDetail", dsReport.Tables[0])); Excited to see our subreport in action All right then, let s move on to building the report.

Open a New Query window in SSMSE (remember to make Northwind your query context). Enter the following query and click Execute. You should see the results shown in Figure 4-17. select o.orderid OrderID, c.companyname CustomerName, e.lastname Employee from orders o inner join employees e on o.employeeid = e.employeeid inner join customers c on o.customerid = c.customerid
