This wizard page allows you to choose the data fields to include into the report.
The selected fields with corresponding captions will be automatically added to the created report and arranged one under another (in the order they are in the data source).
You can stop the wizard at this step by clicking Finish.
To continue report customization, select at least one field and click Next to proceed to the next wizard page: Add Grouping Levels (Single-Query Version).
This wizard page is no longer used in the default Report Wizard implementation. The following master-detail page is used instead: Choose Columns to Display in a Report (Multi-Query Version).
To learn how to switch to the standard Report Wizard version, see the following example online: Report Designer for WPF - How to disable the master-detail functionality in the Report Wizard.
