For example, adding a child band to a data band will result in a row of data and an empty row (the child band row), visually looking like a tall line.

Add data such as country to the child's band.

The image below shows that the country name is printed instead of empty spaces.

This means that if the company, address, phone and contact remain on one page and the second part (here the country) is moved to another page, childband will use the KeepChildTogether property to avoid data corruption. I have.

By default, this property is set to true.
