When you first create and preview a report, the report displays the data rows in the order in which the query returns them. The order can vary, depending on many factors, such as how data was supplied in the data source. In most cases, you will want to change the order in which data appears in the report.
This expression uses the JavaScript toUpperCase( ) function to convert all the customer name values to uppercase before sorting. JavaScript function names are case-sensitive, so you must type toUpperCase( ) exactly as shown. References to column names are also case-sensitive. In this expression, row["CUSTOMERNAME"] is the correct name to use. If you type row["customername"], for example, BIRT Report Designer displays an error when you run the report. You can verify the capitalization of a column name by looking at the name that is displayed in Data Explorer.
