Application structure consists of ASP.NET website, using which the report is streamed to the client as HTML or PDF. This sample describes custom exporting without the Pro Edition server controls or RPX handlers as well as running reports on the server.

Project Details
Reports folder
The Reports folder contains two rpx reports - the Invoice report and the NwindLabels report.
Invoice Report
The Invoice report uses three GroupHeader sections, a Detail section and a GroupFooter section as well as a label in the PageFooter section to display data.
|
Note: Except for the Detail section, all sections come in header and footer pairs. Unused sections have their Height properties set to 0 and their Visible properties set to False. |
ghOrderHeader section
This section also contains a Picture control, a number of Label controls, and two bound TextBox controls. The TextBoxes are bound using the DataField property in the Properties window, and the date is formatted using the OutputFormat property.
ghOrderID section
This section contains a number of labels and bound text boxes, as well as two Line controls.
ghTableHeader section
Detail section
GFOrderID section
This section contains several labels and several TextBoxes. Two of the TextBox controls use the following properties to summarize the detail data: SummaryFunc, SummaryGroup, and SummaryType. For more information, Create a Summary Report.
The Total TextBox does not use the DataField property or any of the summary properties, or even any code. To find the functionality of this TextBox, in design view, click the Script tab at the bottom of the report.
PageFooter section
NwindLabels Report
TheNwindLabels report only uses the Detail section to display the report data.
|
Note: Except for the Detail section, all sections come in header and footer pairs. Unused sections have their Height properties set to 0 and their Visible properties set to False. |
Detail section
This section contains bound TextBox controls and Label controls. This section prints 30 labels per 8½ x 11 sheet.
The Detail section uses the CanGrow property set to False to maintain the label size and the ColumnCount, ColumnDirection, and ColumnSpacing properties to accommodate multiple labels in a single page.
