Overview

In the Report Builder, you can add a Repeater control to a flow document's layout that iterates over a specific header of a given data source. When the report is run, any "child" controls inside the Repeater control will appear once for each iteration.

Currently, the child controls within a Repeater control are automatically arranged in a vertical formation. However, depending on the data being repeated, this can lead to unnecessarily long documents containing lots of pages.

Therefore, we're making it possible to stack repeated content horizontally - by placing the Repeater control within a Horizontal stack control!

Who will be affected?

This will affect new and existing reports containing Repeater controls.

Details

Repeater controls at the root of a flow document will be unchanged.

However, if a Repeater control is placed within a container, the appearance of its child controls will be determined by that container. This means that:

• A Repeater control within a Horizontal stack control will now repeat horizontally.
• A Repeater control within a Vertical stack control will continue to repeat vertically.
• A Repeater control within a Repeater control will behave according to its parent control.
• The Repeater control's Margins and Relative Width won't be applicable.

Initially, repeated content will only appear horizontally when the report is run. The Document Layout Editor will be updated to reflect this new behaviour in the subsequent Alloy release.

Wrap child controls

As flow documents typically use portrait orientation, it's important for Horizontal stack controls to have their Wrap child controls property set to Yes when appropriate. Otherwise, their child controls may go off the page!

Therefore, to ensure that any newly-horizontal content remains visible after the change, we recommend checking your custom reports for any Repeater controls within Horizontal stack controls and configuring them as above.

Expected release

29th June 2023 as part of the Alloy v2.48 release.
