ActiveReports supports newspaper column layouts in both the Detail and Group sections. You can render the columns either horizontally or vertically in the section with options to break the column on the Group section (i.e. start a new column on the change of a group).

There is also a Boolean ColumnGroupKeepTogether property on the GroupHeader. When set to True, the ColumnGroupKeepTogether property attempts to prevent a group from splitting across columns. If a group cannot fit in the current column, it tries the next. If the group is too large for a single column, the property is ignored.

Note: The ColumnGroupKeepTogether property only works when the GroupHeader's GroupKeepTogether property is set to All.

This walkthrough illustrates how to create a simple report using columns, and is split up into the following activities:

Connecting the report to a data source
Adding controls to the report to display data
Viewing the report

Note: This walkthrough uses the Northwind database. By default, in ActiveReports, the Northwind.mdb file is located at [User Documents folder]\ComponentOne Samples\ActiveReports 8\Data\NWIND.mdb.

When you complete this walkthrough you get a layout that looks similar to the following at design time and at runtime.
