For example, add the ChildBand to the DataBand, as the result a data row and an empty row (ChildBand row) is output, visually it looks like a high line.
Add data to the ChildBand, for example Country.
The picture below shows that instead of empty space, the country name will be output.
So as to avoid breaking data, meaning when Company, Address, Phone, Contact remained on one page, and the second part (in our case, Country) was moved to another page, the ChildBand has the KeepChildTogether property.
By default the property is set to true.
