How It Works The data components you dropped on the page, the wizards, and the settings you specified are all reflected in the code-behind page by variable declarations at the class level: Public Class News Inherits FriendsBase ' Web server controls here... Protected WithEvents cnFriends As System.Data.SqlClient.SqlConnection Protected WithEvents adApproved As System.Data.SqlClient.SqlDataAdapter Protected WithEvents cmApproved As System.Data.SqlClient.SqlCommand Protected WithEvents dsApproved As FriendsReunion.ContactsData Each component has its own variable, and the last one the dataset is the most interesting. It s not defined as a generic DataSet, but rather as the custom FriendsReunion.ContactsData class. This is the class that was generated by the adapter when you asked it to do so. The components instances, just like their server controls counterparts, are initialized inside the InitializeComponent() method, which is placed inside the Web Form Designer generated code region. You can take a look inside that method, and you ll realize there s no magic there just raw VB code you could have written yourself. The key point to bear in mind about this demonstration is that the code you wrote to load the list of pending requests in the previous section performs exactly the same task as the code here, and that code took 12 lines to achieve the same results as 3 lines here! That s four times less code certainly not a minor detail. The code has been greatly simplified because all of the variable initialization code is generated automatically. You just need to pass the adapter the value for the current user ID, fill the dataset, and call DataBind() on the grid: ' Fill approved contacts adApproved.SelectCommand.Parameters("@ID").Value = Page.User.Identity.Name adApproved.Fill(dsApproved) grdApproved.DataBind() vb.net code 39 reader VB .

When creating JRXML report templates in different languages, pay special attention to the encoding attribute that can be used in the header of the XML file. By default, if no value is specified for this attribute, the XML parser uses UTF-8 as the encoding for the content of the XML file. This is important because the report design often contains localized static texts, which are introduced when manually editing the JRXML file. For most Western European languages, the ISO-8859-1 encoding, also known as LATIN1, is sufficient. For example, it includes the special French characters , , , and , and can be specified using the encoding attribute shown in the following example: < xml version="1.0" encoding="ISO-8859-1" > <!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD JasperReport //EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd"> <jasperReport name="name_of_the_report" ... > ... </jasperReport> To find out the encoding type to specify when editing XML files in a particular language, check the XML documentation. 10,000 1,112 8.993 400 0.8 * 400 = 320 320 / 8.993 = 35.58 1,112 35.55 = 1,076 Sometimes, you need more flexibility in the rendering of data than is provided by a table with simple row and cell values. ASP .NET supports better customization of output through the use of templates. A template is a piece of ASP .NET/HTML code that can contain binding expressions, and it is used inside a DataGrid column (for example) as a skeleton for each row/cell s representation. The Web Forms Designer offers great integration with this concept, and makes designing with templates a breeze. Scattered rows (20%) Blocks needed for scattered rows Total count of table blocks needed Reported table cost (from 10053) Controls that support templates include DataGrid, DataList, and Repeater.

By default all charts display the legend, but you can suppress this display by setting the isShowLegend flag to false.
