 The SubReport item enables you to display reports within reports and serves as a container, similar to the report sections, growing in size depending on its children.
 
-The following screenshot shows a SubReport item at design time, allowing you to compose complex reports from various report sources. The data for each SubReport can be completely different, for example, you can combine a product listing, a sales summary, and a list of salespeople each in their own sub-report with each sub-report drawing its data from a different source. You can also pass parameters to the SubReport by using the **Edit Parameters** collection editor.

 ## Considerations and Known Limitations
 
 When working with the SubReport item, mind the following:
 
-* Page sections are not related to the report itself, but are relative to the paper or screen. Therefore, page sections of nested or detail reports are ignored and only the page sections of the main report are visible.
+* Page sections are not related to the report itself, but are relative to the paper or screen. Therefore, page sections of nested or detail reports are ignored, and only the page sections of the main report are visible.
+* The `PageSettings` are not related to the report itself, but are relative to the paper or screen. For that reason, they are ignored, and properties as `ColumnCount` won't be respected for the subreport.
 * To render page sections that appear on each page, similar to page sections, consider using an unbound group (no grouping criteria specified) and set the [`PrintOnEveryPage`](/api/Telerik.Reporting.GroupSection#Telerik_Reporting_GroupSection_PrintOnEveryPage) property of its sections to `True`. Note that you cannot use the `PageCount` and `PageNumber` global objects in group sections.
 * The [Table of Contents (TOC) section]({%slug telerikreporting/designing-reports/adding-interactivity-to-reports/table-of-contents/overview%}) is designed to be displayed at the top/bottom of the entire report document. For that reason, the TOC section of the subreport is ignored.
 * To remove blank vertical space in the detail section of a SubReport, set the `Height` of the `SubReport.ReportSource` `DetailSection` to the height of the highest item.
-* Sections can grow to accommodate their children but cannot shrink to hide empty spaces. To make the detail section shrink only at runtime, set the `Height` property of the `DetailSection` in the report constructor. Place the `Height` property assignment code right after the `IntializeComponent()` method call.

 * The default styles used in the subreports may be overridden by inherited styles from their parent reports.
 
-	When Report items and sections use default styles (i.e. their styles are not set explicitly), they will inherit the Styles from their parents. This is valid for the SubReport item and the corresponding subreport specified by its ReportSource. This may lead to inconsistencies when rendering the subreport as a separate report and in a main report. Here is an example for clarity:
